  • Submerged in science 

    Submerged in science 

    By: Alina Ferguson and Emma Wilson

    Diving can take you to magical, strange places that can be beneficial to science, research and our understanding of the oceanic unknown. There are still many mysteries to be discovered in the deep sea. 

    “Humans are not meant to be submerged underwater,” Cal Poly Humboldt diving student Rory Bourdage said. “We are aliens in that world.” 

    At Cal Poly Humboldt, students can enter that alien world through the scientific diving courses offered. This can lead to them getting certified in scientific diving, along with hands-on experience in conducting underwater research and preparing them for a career in marine science. 

    Richard Alvarez, the university’s Diving Safety Officer since 2005, has been diving since 1994. He consults and oversees the diving classes, making sure everyone is staying safe and equipped with diving equipment that is properly maintained. 

    When you go through the scientific diving process, you can get your certificate in American Academy and Underwater Sciences — also known as AAUS — for free through Cal Poly Humboldt. It will take about four semesters, as the classes are not always offered each term. 

    “To get that certification as a scientific diver, you have to do 12 open water dives,” said Alvarez. “What we traditionally do is we learn a scientific protocol, we have people go out and they learn that protocol, they show me that they can do it in the ocean, [that] they can do the extra scientific stuff in addition to being safe scuba divers.”

    Scientific diving is an important skill to have for conducting underwater research, but is also physically and mentally challenging. Common barriers for aspiring divers are the expense, access to training and gear required for getting the AAUS certification. 

    “[There’s] a lot of things that you have to learn so that you can do it safely. Diving in Northern California waters is a couple of notches higher than most other places because our ocean is just a little bit more demanding,” Alvarez said. “We are exposed to a lot of open ocean swells, we see a lot of ocean energy. Our visibility is pretty limited by world standards. You know, we’re pretty happy with five to 10-foot visibility.”

    Marine biology student Rory Bourdage has been in the scientific diving class for almost three years. He is currently a teaching assistant for the scientific diving class. Bourdage is certified as a beginner diver and as a master diver. 

    One of the projects the class conducts is measuring sea creatures, sometimes down to the nearest millimeter, depending on their rarity. For example, a red abalone, an underwater sea snail, will need to be measured as accurately as possible. 

    “In our protocol for the class, we want to measure abalone, for example, since they have been struggling for years, so we want to track not only how many there are in a location, but how big they are getting to get a better idea of their recovery – or decline if that’s the trend that is found,” said Bourdage.

    Bourdage mentioned that it is easier to conduct research in certain areas since the animals are less likely to be afraid of humans. An example of one such place is Catalina Island situated southwest of Los Angeles, a marine protected area.

    This means they heavily restrict what can go in and out of it. Due to these restrictions, the animals are a lot more comfortable with people, compared to other places and sometimes they will come right up to you. 

    “Many of these animals have gone generations without having the fear of humans,”  said Bourdgae. “They can get right up in your face.”

    Rebecca Colyar is a transfer student who started in the scientific program two years ago. She is originally from Fresno, CA, and when she was looking for schools to apply to, Cal Poly Humboldt was the only one to have a scientific diving program, which caught her eye. 

    Colyar’s interest in diving began the summer before her freshman year in high school after her mom took her snorkeling in the Bahamas.

    “That was the one big thing that got me really into ocean life and documentaries,” Colyar said. “I kind of realized if I wanted to do that, if I wanted to tag animals, that I have to scuba dive, like there’s no other way than to start learning how to dive and be comfortable in the water. So, I found out about the scientific diving minor.”

    Colyar is, in a way, a superhero. A large obstacle that may normally scare off some divers, does not deter her. 

    “I have a superpower — I can breathe underwater,” Colyar said. “It’s just that, like, feeling of being in a place where your body knows you’re not supposed to be, and being able to overcome those obstacles that your body and fighting your body to. I feel like there’s a lot of accomplishing hard things.”

    While it may seem like the only people in the diving program are science majors, it is not a requirement. You can have any major or other interest, just as long as you are willing to put in the work for the AAUS certification. 

    “You don’t have to be a STEM major or Marine Science major, you can be anybody,” Bourdage said. “As long as you have the willingness to, you know, take the plunge into the unknown.”

  • New science major is absolutely fire

    New science major is absolutely fire

    By: Griffin Mancuso and Emma Wilson 

    Anti-fire policies and climate change have resulted in wildfires running widespread in Northern California. Forests are in need of experts who can understand the power of fire and its beneficial effects, and channel them into sustainable practices. Cal Poly Humboldt’s polytechnic transformation has resulted in a new addition to the Forestry, Fire and Rangeland Department to meet this need: applied fire science and management, B.S.

    The major explores multiple disciplines and perspectives of fire management, including local Indigenous knowledge and practices. Students will learn about prescribed burnings, how fire exclusion policies have impacted forests and how to use fire to promote biodiversity. 

    This major can lead to careers in fire ecology, fire departments, prescribed burning organizations and more. Students in fire science can also expect a plethora of summer jobs and internships to be available to them.

    However, students who are applied fire science majors do not qualify to take the Registered Professional Forester exam in the state of California. 

    Erin Kelly has been the department chair of Cal Poly Humboldt’s Forestry Fire and Range Land Management since the start of the 2023 fall semester. She emphasized the high demand for foresters and fire ecologists in California.

    “Employers are looking for natural resource managers, people who can apply their scientific knowledge to the ground and also people who can educate others about things like fire management,” Kelly said. “So, we are really in the position of meeting California’s needs in terms of land management, and I think that’s a really cool thing.”

    Fundamentals of Fuel and Fire and Fire Ecology existed prior to the new fire science major, but Fire Behavior and Effects and Fire Weather have been made into their own classes this semester. Additionally, an applied fire internship class will be available.

    Jeffery Kane is a faculty member in the forestry department and has been working as a professor at Cal Poly Humboldt for 12 years. He described the possible careers students can explore with the internship program.

    “Most folks will work for the Forest Service, either fighting fires or doing prescribed burning fuels management stuff, or some will work for CalFire,” Kane said. “Others have worked for nonprofit organizations that are involved with fuels management or prescribed burning…it’s basically, ‘Go out, get experience.’” 

    David Greene, a professor who has researched plant regeneration for several decades, teaches the fire ecology class. Students in fire science classes can expect to go on field trips that allow for hands-on learning and explore the different aspects of the field. Students in Applied Fire Use and Policy will have the opportunity to participate in prescribed burnings.

    “There’s lots of tribes around here that don’t have the capacity to run their own burn. Some like the Karuk and the Yurok can, but others like Bear River – they just don’t have anybody, so they’re often inviting us to go up and do one for them,” Greene said. “Jeff [Kane’s] happy to go do it because he wants the students to get as much training as possible, because California’s embarking on a prescribed burning campaign.”

    Mykie Root, a freshman and forestry major with a concentration in wildland fire management, has enjoyed the practical learning approach and field trips in their fire science courses, compared to reading textbooks in high school.

    “Coming out here and being able to go on these field trips and be able to actually, you know, get into the stuff and be hands on and actually be able to see the trees, you know, take the bark apart, be able to look at all of the rings individually and count them,” Root said. “It’s a lot easier to learn when you’re actually out in it than in a classroom, which is what I prefer. I don’t like being in a classroom. It makes me antsy.”

    Recently, students in Fire Ecology visited the 2022 Six Rivers Forest fire site to document conifer germinates and pine cones in the area that had appeared since the fire. Grayson Voorhees, a freshman majoring in forestry with a minor in fire ecology, took on the task of climbing a steep slope to gather data.

    “Initially we were trying to document the distance from the road to the first green tree to measure the density of the fire, like how far it spread uphill, and that was roughly 150 meters,” Voorhees said. “And that also spread along a transect line, and along the transect we were counting germinate gray pine species.”

    Faculty and students in applied fire science are hoping to destigmatize fire, promote sustainable fire management practices, and combat anti-fire sentiments and policies.

    Root explained how banning prescribed burns entirely allows for leaves to build up and ruin seed beds, resulting in deforestation.

    “When fires come through and actively get rid of all the bad, dead leaves and things that just pile and pile up, leaving for, you know, plants to be able to grow,” Root said. “The fires will come through, burn everything and there’ll be wonderful plant beds for seeds to just be able to pop up and come back. So, fires are really good for us. They’re actually, they’re really good for the forests, and we need them.”

  • Data science makes its debut as one of Cal Poly Humboldt’s new science majors

    Data science makes its debut as one of Cal Poly Humboldt’s new science majors

    by Emma Wilson and Griffin Mancuso

    Data science debuted as one of the eight new science majors that Cal Poly Humboldt is offering this semester.

    Data science is the blend of math, statistics and coding where data scientists examine which questions need to be answered and where to find the related data. Data science is a major with many career opportunities in a variety of fields including mathematics, computer science, coding and research. This major is ideal for students who want to apply their talents in different areas and want to have a practical use for their math skills.

    Currently, one data science class is being offered this semester: Data 111, Intro to Programming and Computational Thinking for DS. In the spring, Data 271, Data Wrangling and Visualization, will be available.

    Kamila Larripa is an associate professor and is currently leading the new data science major. Larripa has been working at Cal Poly Humboldt since 2008 and is currently doing a research project with her students on a type of immune cell in the brain called microglia. She is interested in looking at cells; how they integrate and make decisions in the human body. 

    Larripa previously did some training and started offering her students workshops in data science in 2017, like machine learning and methods or how to clean a data set. 

    “People were really interested, and I just feel like there was kind of this need that students were wanting this,” Larripa said. “And then over time, with a bunch of other people on campus and then the transition to polytech, now we have this new major in the math department.”

    Photo by Griffin Mancuso. Bethany Johnson, an associate professor, describes the first project students are working on in Data 111.

    Bethany Johnson, an associate professor, is teaching the first available data science class this semester. Students taking her class learn the definition of data science, its fundamentals and the skills needed to succeed in their industry of choice.

    “We spent the first part of the class basically learning how to program in Python, so this is kind of like basic programming stuff including how to write a for loop, how to do conditional statements, if-else statements and how to simulate some things,” Johnson said. “And then we start moving into statistics, where we’re trying to figure out, like, how can we use data to make a conclusion about the population. And then toward the end of the class, we’re going to get into a little bit of prediction.”

    Johnson also emphasized data science as a broad spectrum of skills that anyone can benefit from.

    “I think that it’s important for people to view data science as, as not like a strict scientific discipline. You don’t have to be a computer whiz or something like that,” Johnson said. “I think that sometimes when people hear data science, they maybe don’t even know exactly what it entails… I would think about it as just like, sort of a discipline to help you solve problems and make decisions, work with the data and the information that’s out there.”

    Elio Piccagli is pursuing a major in computer science and data science along with two minors in biology and art. Currently, Piccagli is in the Data 111 class doing a project on the world population’s relationship to poverty levels. He explained the commonalities and differences between computer science and data science. 

    “Computer science deals with like a lot of, ‘how do we code this,’” Piccagli said. “And data science is like, ‘we have this data, how do we make a table visualizing that data?’ So it’s just like the application of computer science.”

    Emad Syed is a junior majoring in data science who pursued the major out of an interest in manipulating data rather than creating it. He also emphasized the flexibility of possible career paths students can pursue with a data science major.

    “I’m looking for something that can be applied in all, in all parts of life,” Syed said, “Be it forestry, economics, statistics, computers, anywhere where the skill set can be used. I don’t want to necessarily choose a specialized field.”

    Larripa has hope for the future of the data science program at Cal Poly Humboldt

    “So the overall theme of our program is really data for good. Like how can we, you know, capture, analyze data and make decisions so that we’re making the world a better place?” Larripa said. “And I mean, I think that really is in line with the Cal Poly vision. And we’re really excited about that.”

  • Marine biology joins Cal Poly Humboldt’s available science majors

    Marine biology joins Cal Poly Humboldt’s available science majors

    By Emma Wilson and Griffin Mancuso

    The new marine biology major provides students the opportunity to gain practical, hands-on experience in ocean and marine habitats. They will study different organisms and a diverse selection of marine ecosystems, such as salt marshlands and beaches. 

    First-year, first-time students will also be enrolled in Rising Tides, a year-long program of science and general education courses and activities specializing in the Humboldt and Trinidad bays. 

    Photo by Griffin Mancuso. A collection of microscope slides.

    Sean Craig, a professor at the university for 23 years, explains the need for marine biology professors and lecturers.

    Currently, there are only three professors teaching marine biology classes, according to Craig. 

    “We asked for a new faculty member for our new marine biology major but we didn’t get it,” Craig said. “We only got a chance to replace one of our faculty who retired and left.” 

    “Starting in the spring there will be four because we are able to replace the one who left,” Craig said. 

    According to Craig, the university always had a marine biology program, but after becoming a California polytechnic now with the transition you can now declare in marine biology as a major. 

    “The fact that [marine biology] is now a major it rings more bells and connects with more people, especially people applying to Humboldt,” said Craig.

    “Our marine biology major already borrows heavily from other marine majors, especially oceanography and fisheries,” said Craig. “I think it would be good in the future to have all us marine scientists to pull together and decide on things together to make an impact.”

    “I think there are a lot of misunderstandings of the ‘marine biology major’ because really, at least at the moment, firmly in the biology department there are only 3 faculty at the moment teaching marine biology,” said Craig. “Like saying we got the best restaurant in the world off the highway, but we don’t have a sign.” 

    Craig expresses great discernment and feelings about the lack of professors teaching marine biology. 

    “Our biggest problem, which is a long term problem, we have been clambering for years for faculty,” Craig said. “All students benefit better from support systems, tutors and writing center help. All of that is better with more numbers.” 

    It is not unusual for a professor in marine biology to have 55 students. 55 students that need those professors help to figure out what classes to take, or what to retake, especially during registration. This is frankly a lot of students for one professor. 

    “It’s a problem, we don’t have enough faculty to do a good job of advising and providing opportunities for students,” says Craig. “We are handicapped, we can’t keep up with students increasing and with the faculty decreasing.”

    “We were promised a new faculty member and we haven’t gotten that, yet,” said Craig. “We’re all going to have to work together to get exposure and make connections.”

    A really cool and fun thing that you can do as a marine bio major is go on the Coral Sea, which is a research vessel and is 91 feet long. It’s parked on the docks in Eureka in the Woodley Island Marina, and is a wonderful platform for learning. It is the only vessel of its kind in size in California that is devoted to undergraduate education. 

    “The vessel itself is in pretty good shape, but the engines not up to standards in terms of output of different particulates in the air, so there is a major problem there, and to solve that problem so many of our faculty and Associate Dean are working together to, as part of the poly tech transformation, purchase a new brand new vessel that would be better in multiple ways. Eventually I hope there will be a new version of the Coral Sea,” said Craig.

    “Now we have a major, we have a 91 foot research vessel that students can go on cruises for, we have a marine laboratory where students can learn about live animals like crabs and octopus under a dish in a microscope,” said Craig. “Thanks to Cal poly tech, we got new microscopes for the marine lab. Many before dated back to the 1950s, so the new facilities after the Cal poly transformation makes our marine biology department even better.”

    Kaci Dodd, a junior who changed her major to marine biology this fall, aspires to work in marine conservation or scientific diving instruction. She expressed excitement about marine biology having its own program at CPH.

    “Now that they’ve added it more as a major, there’s definitely been more classes and more opportunities — which is super exciting — instead of just having biology with a marine concentration, “ Dodd said. “But I feel like what really attracts people to the marine biology program at this school is how hands-on it is with the equipment that they use and the professional element.”

    Dodd recalls her experiences learning how to use new technology and gear on the Coral Sea. 

    “One of my favorite things in the biological oceanography cruise… It was an otter trawl, “ Dodd said. “And it pretty much was a huge net that went along the water column and collected all the fish or whatever was in that water column. And so we saw a lot of fish, some squid, that was really cool.”

    Dodd also recommends that any student, marine biology major or not, should try the field techniques class taught by Daniel O’Shea.

    “It was just like, so fun — fun to be on the boat and meeting the crew that works on the boat, how to work on the boat, and be a cruise assistant,” Dodd said. “And after that class, when you pass, you’re able to actually become a cruise assistant and work on the boat with cruises and classes, like that is really cool.”

    Marine biology students, along with other majors, analyze marine organisms at the Telonicher Marine Lab, located in Trinidad and home to various marine species and preserved specimens. The lab is open to the public on weekdays, and students also travel there for class labs and research.

    Kyle Bailey, a junior and zoology major who wants to pursue a career in animal husbandry, described his experience with the marine biology classes at Telonicher Marine Lab.

    “I’m taking invertebrate zoology right now… the class we’re taking is a crossroads for several different majors,” Bailey said. “I’d say the majority are marine bio, but there’s a couple of us who are just general zoology, wildlife, there’s a few others in there.”

    Bailey elaborated on what sets classes at the marine lab apart from other biology classes.

    “The main difference between the lab now and from intro zoo is looking at live specimens,” Bailey said. “It’s super cool to see how these animals would actually look living and we have the sea table to look at stuff. It’s a big difference to see what these animals would look like living as opposed to mush in a jar, which I think is a super fun experience.”

  • Decriminalizing entheogens for mental health

    Decriminalizing entheogens for mental health

    by Maranda Vargas

    It is a sunny afternoon, and Cal Poly Humboldt student Camryn Hanf is standing in front of the Student Activities Center with a stack of petitions for potential supporters to sign and send to the Eureka City Council in support of decriminalizing the use of specific entheogens within city limits.

    Hanf moved to Arcata a little over two years ago to pursue a degree in psychology. Quickly after moving to the area, Hanf expressed she felt an innate curiosity towards psychedelics. One afternoon while at the Arcata Farmers Market, she saw a table for Decriminalize Nature Humboldt. Although she says she felt nervous about approaching due to anxiety she had at the time, she felt compelled to approach the table and quickly joined the cause.

    “I feel entheogens are not the answer for everybody,but they are absolutely life changing for some people,” said Hanf. “I feel strongly that people should have the choice whether to use them or not.”

    Photo by Maranda Vargas | Camryn Hanf sits with a stack of petitions in front of the Gutswurrak.

    A California State bill that will decriminalize the usage and possession of entheogenic substances, plants and fungi was passed by the state assembly and has moved along to Governor Newsom’s desk. Newsom has until Oct. 14, to veto or approve the bill. 

    The bill was sponsored by Senator Scott Weiner and will decriminalize the possession and use of a list of approved psychedelics for adults 21 years of age or older. If Governor Newsom approves the bill, it will go into effect on Jan. 1, 2025, making California the third state to decriminalize entheogens for personal and medical use. Orgeon legalized the use of entheogens in 2020, while in 2023, Colorado legalized the usage of certain psychedelics, including psilocybin containing mushrooms. 

    The usage of naturally occurring psychedelics known as entheogens are being studied for their potential in treating and alleviating anxiety, depression, PTSD, addictions and cluster headaches. Psilocybin containing mushrooms are one of the proposed entheogenic substances on the list that has been gaining the attention of research hospitals and institutions for its treatment of mental and physical health issues. The bill, SB 58, would end the practice of criminalizing access to entheogenic substances despite their potential benefits.

    “Veterans and anyone suffering from PTSD and depression should not face criminal penalties for seeking relief,” said Senator Wiener in a press release. “Plant-based psychedelics are non-addictive and show tremendous promise at treating some of the most intractable drivers of our nation’s mental health crisis.”

    The Department of Veterans affairs has advocated for the need to study the therapeutic usage of entheogens such as psilocybin containing mushrooms for the treatment of PTSD, depression and substance abuse disorders. 

    The usage of naturally occurring psychedelics found in entheogens as a therapeutic treatment for mental and physical health issues is being studied at a rapid pace by research hospitals as well. Johns Hopkins Hospital is a non-profit academic and research medical facility that has a Center for Psychedelic and Consciousness Research that has been conducting studies exploring the medical usage of psilocybin for over twenty years. 

    Those who live in the cities of Arcata, Oakland, San Francisco or Santa Cruz where entheogens have been decriminalized can use the approved psychedelics. Entheogens have been decriminalized in Arcata since the city council approved the measure almost two years ago. 

    “I have only used it a couple times myself. I think it’s really helped me feel more of a connection to all living things,” said Hanf. “I had this one experience that was really helpful for me. I used to struggle with being alone quite a bit and didn’t really feel capable of helping myself out of my rut or like, my bad feelings… and during that experience, I was opened up to, you know, like the voice in your head. That’s kind of just stuck with me. I would call it like an older Cameron, kind of guiding me through.” 

    Cal Poly Alumnus Danielle Daniel of Decriminalize Nature Humboldt presented the Eureka City Council with 105 letters from the community in support of decriminalizing entheogens for personal use at the first council meeting of September. 

    Decriminalization would make the possession and usage of entheogens a low priority for law enforcement. It will allow for those over the age of 21, the ability to grow, gift and gather entheogens. If the measure is approved to decriminalize the usage of entheogens within city limits, the law prohibits entheogens on school grounds, the sale of entheogens, impaired driving  or being a public nuisance. 

    “The decriminalization model is needed so people feel safer to heal with these medicines and have safe access to these medicines,” said Daniel. “The freedom to grow, gift and gather without having a fear that they are stepping over the line to some regulation which is going to turn them into a criminal.”

    The Eureka City Council can decide on the proposed decriminalization measure to allow the usage of the approved entheogenic plants and fungi within city limits. On Thursday, Sept. 28, there will be a community roundtable open to the public from 6 to 8 p.m. at the Labor Temple community center to discuss the decriminalization of entheogens in the city of Eureka.

    “I think in this climate with mental health issues being so prominent and profound, it’s important that we look at all avenues of treatment,” said Bergel.

    Eureka Mayor Kim Bergel said the Eureka City Council sent a letter to the state in support of State Bill 58, which will decriminalize entheogens in California. If the Eureka city council approves the proposal, they will be following in the footsteps of Arcata.

     “On a personal level, I do support this coming forward,” said Bergel. “I know so many people with PTSD and different trauma problems that this has helped.”

  • Water hazards in Humboldt County 

    Water hazards in Humboldt County 

    by Griffin Mancuso

    One of the perks of living in Humboldt County is access to the lush, sprawling redwoods and the coast, both of which are teeming with wildlife and great photo opportunities. With multiple beaches and rivers nearby, it may be tempting to brave the chilly waters with friends. If this is something you are interested in, do so at your own risk.

    BLUE-GREEN ALGAE

    The most prominent risks you will face in Humboldt’s waters are the blue-green algae in lakes and rivers, and rough currents and sneaker waves in the ocean. Blue-green algae, also known as cyanobacteria, is something to watch out for during warmer weather in Humboldt. Its growth is fostered by nitrogen or phosphorus, which can be spread by runoff from cities during rainstorms. It can turn the water into a variety of colors and is more likely to bloom in slow-moving or still water at warmer temperatures, but it can also grow in the ocean with the right conditions. 

    It can also be incredibly toxic to you and your pets if ingested. The Associate Dean of Marine Operations at Cal Poly Humboldt, Rick Zechman, says that even eating clams, oysters or mussels that have ingested toxic blue-green algae can have serious consequences.

    “If you eat something that’s been concentrating Alexandrium or another toxic [genus of algae], your tongue starts to go numb, and your throat can become somewhat paralyzed, and it can cause you to stop breathing,” Zechman said. “ It can make you really sick, like vomiting and diarrhea. It can cause short-term memory loss. That’s where this idea of amnesic shellfish poisoning comes from.” 

    While blue-green algae isn’t always toxic, there is no way to identify when it is or isn’t. Stay away from the water if it has a bad smell, is discolored, has green foam or mats on the surface, or there are many dead fish or animals nearby.

    SNEAKER WAVES

    While Humboldt’s beaches offer plenty to explore, it is critical to keep a close eye on the waves. Sneaker waves, which appear suddenly and move very fast, are only seen in Northern California, Canada and Australia. Bridget Nichols, the Associate Director for Campus Recreation, emphasizes the importance of having awareness of your surroundings at the beach.

    “If people aren’t keeping their eye on the ocean, they don’t really know the power and the impact,” Nichols said. “Trying to run away from a sneaker wave on a really steep beach – such as a place where you might go agate hunting or something like that – it’s going to be very different than at Moonstone Beach, where it’s a flat beach and you’re able to move a lot quicker through the sand.”

    Photo by Griffin Mancuso. A sign warning visitors of the risks they face by standing on the jetty at the Samoa Dunes Recreation Area.

    Tamara Barriquand, an assistant professor in oceanography and physics, explains the science behind sneaker waves and why they are more of a concern at steeper beaches.

    “As a wave is coming into shore, it behaves as what we call a deep water wave. And then as it gets below, half the wave, like the depth… it’s now a transitional wave that’s starting to feel the bottom,” Barriquad said. “And so if that gets really shallow, really fast, all that energy is getting pushed up into the wave. And so you can get this wave that can get generated very, very big very, very quickly.” 

    Sneaker waves are strong enough to knock you over and pull you into the ocean. These can occur no matter how calm the ocean appears.

    COLD WATER AND RIP CURRENTS

    The immediate concerns while swimming are the cold temperatures and rip currents. When the body is suddenly submerged in cold water, it can go into cold shock, which causes temporary muscle paralysis. Nichols strongly recommends wearing a life jacket when going kayaking or rafting in rivers. 

    “When you first fall in the water your immediate reaction is to do a big inhale of breath and if you’re underwater, you can easily choke. So [the life jacket] is buying you time to get over and cough… it’s buying you time to orient yourself to your boat and get back to it. And if you can’t get back inside of the boat, it’s buying you time when your muscles stop working for a second.”

    Grace Oliva, the Assistant Outdoor Program Coordinator and US Sailing Instructor for Center Activities, explains how rip currents are formed. 

    “There will be a small divot in the beach right where the shoreline is, right where the water meets the sandy part. Over time, that can actually cause a deeper section in the beach… So when the water comes up on the beach from a wave, water always likes to go the path of least resistance and if it can go faster [or] farther, it will.”

    Thankfully, it is possible to identify rip currents from the beach. Barriquand describes the visual signs to look out for, including white foamy water that builds up and is pulled out beyond the breaking waves, resulting in a noticeable difference in coloration between sections of water.

    “The other thing you’ll see is right where the rip current is going, there won’t be any waves breaking in that location,” Barriquand said.

    Rip currents are often dangerous not because of their strength, but because swimmers don’t know what to do in a rip current. If you find yourself caught in a rip current, Gracie Oliva strongly discourages students from trying to escape or swim against it.

     “You kind of just ride it like a lazy river,” Oliva said. “And then once you’re out of it, you’ll feel it. You’ll pretty much stop moving as much and then you can swim parallel to shore, and then you can swim into shore.”

    If your friend or pet is caught in a rip current, attempting to rescue them can also put you in danger.

    TSUNAMIS 

    The least common but most dangerous beach hazard is tsunamis. While living in earthquake country puts Humboldt at a higher risk of experiencing tsunamis, they can sometimes be caused by other events, including landslides and storms. While tsunamis can travel from far across the ocean, they are easier to spot as they approach the shore. 

    “If the water got really, really low really, really fast, then you’re seeing the trough of the tsunami,” Barriquand said. “And behind that is going to be a big wall of water.” 

    If you notice these signs at the beach, head to high ground immediately.

    When planning a trip to the beach, take the tide into account to prevent yourself from getting stranded, and read the surf report if you plan on going swimming. Be aware of cliffs and sudden drops while hiking near the beach and never turn your back on the waves once you’re on the shore. 

    If you are traveling somewhere with no reception, tell someone where you will be. In the water, a wetsuit or life jacket is recommended even for experienced swimmers. Most beaches in Humboldt will have blue signs detailing the potential hazards there and how to handle them. In the rare case of a tsunami, learn your local evacuation routes.

  • Research vessel brings students face-to-face with ocean creatures

    Research vessel brings students face-to-face with ocean creatures

    by Brad Butterfield

    Originally printed April 26, 2023

    Two diesel engines churn out over 1000 horsepower into the frigid waters of the Humboldt Bay just after 8am on April 22. On-board, a small team of students, professors and crew members enjoy the calm waters of the Woodley Island Marina before entering the rolling Pacific. Though 49 years old, Cal Poly Humboldt’s science vessel, The Coral Sea, has gone through many rounds of facelifts over the years and is nearly unrecognizable from her original form of 1974. With the 2008 refitting of two new diesel engines letting out a steady hum into the misty Pacific air and a recent paint job displaying ‘Cal Poly Humboldt’ in perfect white text on the forward bow of the ship, the old girl looks and sounds like a much younger yacht.

    Before exiting Humboldt Bay’s enterprising mess of wave-dissipating concrete blocks, Captain Jim Long kills the engines. Oceanography students donning hard hats carefully deploy a long fishnet and heavy metal trawling doors.

     The Coral Sea’s wild years have been long left in her wake. She was bought by the then-named ‘Humboldt State University’ in 1998. Though obediently committed to science now, echoes of her wild years can be found around the boat. Kept behind a metal door on the port side of the deck, a paper copy of a 2017 article in the North Coast Journal titled: Past Lives of the Coral Sea details the vessel’s younger and more wild years. 

    One time owner of the boat, Ronald Markowski, used the boat in the 1980’s as a, “floating headquarters from which he radioed instructions to a team of pilots coming in from the Bahamas,” Sam Armanino writes in The North Coast Journal. Those pilots were pawns in a much larger scheme which smuggled cocaine and marijuana from Colombia into Florida and eventually, the greater United States. Eventually, these unlawful escapades would lead to a 45 year sentence for Markowski and the seizure of the Coral Sea by The DEA. The long arm of the law would later use the Coral Sea in an operation coined: The Albatross Sting, which saw the yacht rigged with audio and video recording equipment. The operation hinged on the cooperation of former Markowski associate, Frank Brady, who would lead to the downfall of the sting when the DEA discovered he had, “continued to smuggle cocaine under their noses,” Armanino writes in the NCJ.

    Decades beyond her drug-days, now associated with Trinidad’s Telonicher Marine Lab, the Coral Sea’s massive a-frame arm, with a capacity for 5,000lbs, guides in the students’ systematically laid out fishnet released ten minutes prior. Today, Oceanography 260 students are out on the last of their cruises for the spring semester, focused on marine biology. 

    Adjacent to  modern flat screen navigation monitors, student Maddy Ho is filling out a worksheet tallying the living organism totals (hand counted by the students) that were caught in the first trawl of the day. Top of the list shows: 138 Dungeness crab, 147 shrimp,  27 ctenophores, or comb jellies.  

    Photo by Alex Anderson | Oceanography student Miriam Cima holds up squid that was caught using one of the R/V Coral Sea sampling nets.

    “We do four cruises per semester,” Ho explains. “Biological, geological, chemical and physical.” 

    Powering three miles out into the open ocean, the Coral Sea was finally home again, riding growing waves. Those not quite at-home made good on Captain Jim Long’s advice given at 8:00 a.m. before leaving the marina. 

    “If you’re going to get sick – it goes over the side. Try to do it on the downwind side,” Long said. 

    As a couple of students stood queasy on the starboard side of the sturdy yacht, Trinity Abercrombie explained the critical role the Coral Sea plays in education. 

    “I don’t think that I would be into this major as much as I am if it weren’t so hands-on. The Coral Sea is definitely a hands-on experience and you get to be in the field working as soon as you join the major.” Abercrobie said before adding, “ It gives you a perspective on your future – like what you’re actually going to be doing in the field later on.”

    In between exercises carried out by students of oceanography 260, a small team of students conducted the first series of measurements as part of their year-long senior project. One member of this team, Simon Kurciski, served six years in the Navy, completing many long submarine missions. His longest stint below the surface, Kurciski said, was 51 days. Now though, Kurciski’s time at sea serves a much different purpose. 

    “We are comparing the effect of different photosynthesizers in the water on the chemistry of the water surrounding them,” said Kurciski. “Specifically we are looking at the effects that eelgrass in Humboldt Bay and kelp up in Trinidad have on perimeters like acidity, dissolved oxygen, total carbons, CO2.”

    Kurciski and his team methodically gather water samples from two meters below the surface, then transfer the water into empty beer bottles. The amber tint of the bottles coupled with mercuric chloride added by Marcos Moreno gives the researchers a time capsule of sorts. The tint blocks light from further affecting the biological material.

    “The reason we are adding these chemicals is to essentially stop the biological processes,” Moreno explains. 

    While the sampling is conducted exclusively off of the California coastline, Kurciski emphasizes that the results will reflect the real world implications of human-caused climate change. One test result that specifically interests Kurciski is the samples’ pH.

    “Since the industrial revolution the ocean has increased in acidity by around 30%. That’s huge. We’re already living in an ecosystem that has been dramatically altered by humans in every way,” says Kurciski. “We’re trying to catch up and understand the effect of the changes that we’ve already brought.”

    “The sad thing about climate change -and broadly, human-caused changes- is that a lot of the change is already locked in… deep ocean water circulates very slowly,” said Kurciski. “The oldest deep ocean water can be up to 1000 years old – in the Pacific. That extra carbon that we’ve put in there – that isn’t going anywhere.”

    The future of the Coral Sea will again be determined in-part by an arm of the US government – though this time it’s not the DEA. Instead, hawk-eyed regulators in California will play a large role in the Coral Sea’s future. 

    “The CA air quality resources board is mandating that we replace all of our engines – we have five engines,” Long explains from the ornate bridge of the ship. He’s been working on the Coral Sea for fifteen years, serving as captain for three. “We’re looking at a half million to a million just for new engines by 2025. And then we still have an old boat. So we are trying to decide what to do to go forward. There’s going to be some big changes coming.” Importantly, Long assured, “The Coral Sea is not going anywhere.”

  • Humboldt home to remarkable conifer collection 

    Humboldt home to remarkable conifer collection 

    by August Linton

    Originally printed April 12, 2023

    Nestled between the science buildings, fronds sway in the breeze, fallen needles line the edges of paths, and cones of all shapes and sizes swell and release pollen or seeds. A deft hand plucks berries from one, and rolls between callused fingers the foot-long leaves of another. Professor emeritus of Botany Dennis Walker strolls slowly from plant to plant, and knows them all by common and scientific name, without a glance to the placards which define them. 

    The Cal Poly Humboldt campus hosts an extensive collection of conifer species in the Science Complex Conifer Collection, ranging from local Coast Redwoods (Sequoia sempervirens) to the Japanese Umbrella Pine (Sciadopitys verticillata.) Over 65 species of conifers grow close to the classrooms where they are studied, a collection that rivals the top universities in the United States. 

    Professor Emeritus of botany Dennis Walker made it his mission to expand the university’s collection, traveling to Australia, China, Chile, and many other places around the globe to bring back trees to use for teaching and research. 

    “In the beginning, I could simply go down to the local retail nursery,” said Walker. 

    After he had exhausted the list of plants available locally, Walker turned to botanical collections, cultivating relationships with other botanists and collections worldwide. 

    “It’s great to be a botanist in the jet age,” said Walker. “I was traveling with a backpack on my back, in my grubby clothes to slop around in some tree fern gully or something of the sort, complete with leeches.”

    The collection is used by botany professors as a teaching resource, supplanting the need for jars of leaves, branches, and cones suspended in preservative. 

    Conifers are diverse in lifestyles, appearance and native habitat. Iconic examples of the group have dark green, skinny needles and small, pointed cones, but others have broad leaves, paired cones, or sweet, edible cones. The Plum Fir (Podocarpus elatus,) planted next to Science B, grows translucent-white, cherry-sized cones when in season. 

    Their diversity makes conifers a valuable resource for botanists who study paleobotany, the science of ancient plant form and evolution. 

    “Just collecting what is available [in Humboldt] is an easy way out, but students get a very narrow and inaccurate view of what the whole taxonomic order Coniferales represents,” Walker said. “They cannot conceive of something with a slightly widened leaf like that…you can tell them that there are such things, but it’s better to show them.”

    The climate in Humboldt is uniquely suited to accommodate an extremely wide variety of plant species, one factor which made the collection possible, according to Walker. Some frost-tender plants are able to be planted outside, an important factor since the greenhouse severely limits their growth.

    “There’s a banana belt that we’ve identified, where the cold air intake for the mechanical room keeps the air moving on the south side of [Science] A,” said Walker. “That was about the balmiest environment we could find.”

    One species that Walker was unable to find for the collection was the parasitic conifer Parasitaxus usta, which grows on another conifer species. He traveled to New Caledonia to seek specimens of the plant, but was unable to find any. The host plants on campus weren’t strong enough to host the parasite either, according to Walker. International regulations on transporting plants across borders made it difficult to bring some specimens back into the country.

    Arborists and student volunteers tasked with caring for the trees once Walker brought them back home have struggled to keep some species alive. Many individuals died from water mold, and some Southern Hemisphere species can only be kept in the greenhouse that bears Walker’s name. 

    Walker laughingly refers to botany professor Mihai Tomescu as his replacement. Tomescu describes the collection as a tool both for teaching and for research. A former masters student of his, Kelly Pfeiler, is now pursuing a PhD at the University of Kansas. She recently returned to the CPH campus to collect cones from specimens in the collection, to use as reference for paleobotanical research. 

     “She’s one of several people who have come through over the years from other campuses to collect here, because it’s a very diverse collection,” said Tomescu. “Dennis left a great legacy here.”

  • Community blooms during Humboldt Orchid Society show

    Community blooms during Humboldt Orchid Society show

    by Harrison Smith

    Originally printed April 26, 2023

    On Saturday, April 22, the Redwood Art Association in Eureka was packed. The gallery usually displays the work of local artists, but on Saturday, almost every free surface was dripping with shining leaves and fragrant petals. The hum of conversation was electric and the sense of shared delight in the flowers was palpable. The Humboldt Orchid Society’s spring flower show and sale was a scientific and sensory delight. 

    Orchids can be found on every continent. An extremely diverse family of organisms like orchids living over far-spread habitats is usually an old one, evolutionarily speaking. Flowering plants, also called angiosperms, first appeared around 150 million years ago during the Jurassic period. Pangea was still in the process of breaking up. The first species of orchids appeared 112 million years ago, early in the history of angiosperms. This early evolution allowed them to fill up a huge variety of ecological niches.

    “Most orchid seed is dustlike, so it spreads by the wind. The seed of vanilla is very heavy, and cannot be dispersed by the wind,” said Mike. “There are species in Eastern Africa that are the same as in Florida, because the seed was carried by the winds coming from Africa.” 

    The dustlike seeds of orchids younger than vanilla have allowed them to spread into diverse, far-flung habitats. Various species of orchids have adapted to bloom at the crests of sand dunes, grow free-floating in icy streams, or thrive in piles of humus on the forest floor.

    “The really unique thing about orchids at that level is that orchids don’t produce a traditional seed,” said Blaine Maynor, owner of Orchids for the People. “A seed by definition is an embryo and a food source. Orchids don’t include that food source. It’s basically what we call a naked zygote, and it’s basically just 13 cells and a veneer on it.” 

    When seeds are dispersed from a plant, they require a source of energy to begin the expensive process of germination. By not including the food source, orchids are able to produce more seeds by an order of magnitude.

    “In some of these bigger flowers over here,” said Maynor, gesturing to the beautiful array of orchids on the table before him, “a seed pod may have 2 million seeds.“

    Orchids are able to adopt this highly successful strategy due to their unusual (though not unique) symbiosis with mycorrhizal fungi.  

    “When they’re germinated they need to have a fungus presence, because what they do is they basically intermesh with each other. The orchid gives the fungus sugar, and the fungus gives the orchid micronutrients,” said Maynor. “A lot of times the fungus actually has an apparatus that will go into the tissue and weave its way through the cells.” 

    Humboldt county is home to 33 native orchid species, more than any other county in California. Mycorrhizal fungi thrive in the coastal rainforest environment, where organic matter accumulates quickly in the wet understory. Readers are advised not to attempt digging up a wild orchid for their garden, however beautiful the plant is. Without its supporting fungus, the orchid will quickly lose its ability to uptake nutrients and die. 

    Readers are advised, however, to bring any ailing orchid they may have to the monthly meetings of the Humboldt Orchid Society, which are open to the public.  Meetings are held every third Wednesday of the month at the Redwood Art Association.

  • Humboldt alumnus brings back beavers to restore California wetlands

    Humboldt alumnus brings back beavers to restore California wetlands

    by Harrison Smith

    Originally printed March 1, 2023

    For millions of years, beavers have been the stewards of North American watersheds. Over a hundred million used to ply the streams of the continent. Hunting and habitat loss since colonization have reduced their numbers to somewhere between 10 and 15 million, and many ecosystems which historically relied on beaver stewardship are now absent of the aquatic rodents. In 1941, there were just 1,300 beavers in California. Symbiotic Restoration, founded in 2018 by CPH alumnus Garrett Costello, is a company which seeks to reverse this loss of habitat.

    “Our mission is to improve stream and meadow conditions to bring back the beaver,” Costello said, who graduated from Humboldt with a BS in environmental protection and management.

    Founded in 2018, Symbiotic Restoration (SR) has carried out all of their restoration projects in Northeastern California. Costello, who recently moved back to the county, hopes to partner with local Humboldt organizations to carry out restoration projects in the future.

    The vast majority of SR’s restoration projects involve the building of beaver dam analogs, or BDAs. BDAs come in many forms depending on the size and condition of the stream, but they’re usually built as a short, unobtrusive lattice of maple limbs which act to trap sediment and slow the stream. Human activities, especially road construction and agriculture, cause interruptions to stream flow and increase bank erosion.

    “Let’s just think about cattle for a moment. They cross the same place every time. They are going to soften that soil and they are also going to punch it down a little bit,” Costello said. “Once the water starts falling into the drop, that fall of the water is what causes the erosion and then will continue to unzip.”

    BDAs are constructed at points in the stream where flow has been interrupted by a head cut, acting to fill the depression and preventing erosion from continuing upstream. 

    “As water hits that pond, it slows down and drops and that will slowly build sediment behind the structure, which then strengthens the structure and then it helps reconnect the floodplain because now we don’t have this incision,” Costello said.  

    Once the stream has been reconnected to the floodplain, the stream is able to meander more widely around. This turns a stream flowing quickly through a deeply cut channel into one which supports a wide, dense belt of riparian vegetation with its lazy flow. 

    Most of SR’s project sites are in places too remote for construction vehicles, where their use would undermine restoration efforts. Costello and his crew carry out their work the old fashioned way— with sweat, shovels, and axes. 

    “We’re not out there with heavy equipment, huge amounts of diesel, coming down into the meadow and potentially causing soil compaction, some disturbance to the vegetation,” Costello said. “We’re on foot and I have sleds. I don’t use wheelbarrows because the tires can cause little ruts, so we’re pulling everything on these duck hunting sleds.” 

    SR has worked closely with the Natural Resource Conservation Service, a subagency of the Department of Agriculture, which provides funding to ranchers and farmers on the condition that they meet certain restoration requirements. 

    “The program is to incentivize private landowners to do conservation efforts on their land,” Costello said. 

    One goal of SR is to involve the communities in which they work as stewards of the land, fostering a bottom up approach to conservation. 

    “Last year, we partnered with Point Blue Conservation Science… we had 50 kids a day come from local elementary through high school to build beaver dams and plant willows with us,” said Costello. For the children, it was fun to build beaver dams in their community creeks.

    “And all these kids were so stoked,” Costello said. “‘Oh yeah, go in the woods around here.’ Or,  ‘Yeah, my parents work for the timber company in the town. We go hunting out here’. They have that sense of place,” 

    Even though much of SR’s work is still focused in Northeastern California, Costello hopes to make connections with local Humboldt community organizations in the future. He recently spoke to students in a capstone restoration course, and hopes to form a dedicated Humboldt crew to work on restoration projects in the county. 

    “Volunteers come from all over too, so not only local communities, which we want to target to get that sense of place and stewardship.” Costello said. “Folks are coming from all over California that are interested in this because it’s really fun. We’re like kids playing in a creek.”

  • CCAT begins reconstruction project

    CCAT begins reconstruction project

    by Emma Sjostrom

    The Campus Center for Appropriate Technology began construction of a tire retaining wall in their on-campus garden at Buck House. Constructed by CCAT directors, instructors and volunteers, the retaining wall is part of CCAT’s project to rebuild the existing Reclamation Station structure located in their garden. The structure has served as storage for students to donate and access reclaimed building materials. 

    Made from used tires, the retaining wall is needed to support the sloped landscape where the structure is located. Following the wall’s completion, project managers and volunteers are working towards utilizing natural building materials to complete the project. 

    The goals of the rebuild are to increase usage of reclaimed materials through safer and easier access. With a budget of $1,000, the project is proposed to be completed by May 5th of this year. 

    Spearheaded by project organizer Maddy Hunt, the project is aimed at promoting sustainable practices and techniques as well as serving as an example of utilizing appropriate technology in construction projects. 

    “The shed uses natural building methods which are focused on using reclaimed materials, minimizing ecological impact, and inviting community participation,” Hunt said.

    Plans for the rebuild include construction of a wall made of hempcrete, a natural alternative to concrete. CCAT intends to collect data on usage of the material within Humboldt County in an effort to understand and demonstrate the feasibility of hempcrete to address housing needs within the community.

    External Co-director James Lara added that CCAT’s overall goal is to encourage sustainable resource and energy use.

    “We are in a live-in demonstration home for sustainability and to live lightly on the Earth,” Lara said. “It’s about engaging students to have more experience with sustainable living.”

    Construction of the retaining wall is nearly complete, and project organizers expect to continue the groundwork for the structure in the next coming weeks with the help of students and volunteers. Hunt aims for the project to be a practical example of the organization’s goals.

    “It can be a demonstration for Cal Poly Humboldt,” Hunt said. “Especially for us to demonstrate [sustainability building] here at CCAT. It’s going to be a really cool way for us to connect with that and to be a part of that process.” 

    Hunt added that the project has potential for showing the university and surrounding community the viability of natural building, noting the relatively quick project timeline.

    A soon-to-be graduate from the Environmental Studies program, Hunt mentioned that the reclamation project is the culmination of what she has learned in her degree. 

    “It’s equally stressful as it is gratifying to be putting theories into action, and seeing it come together as not only a completed project in the end, but also as a network of people working towards a sustainable future,” Hunt said.More information on the project and techniques being used can be found at www.appropedia.org/CCAT_reclamation_station_2023. Those interested in aiding in the project’s completion are encouraged to participate in CCAT’s Volunteer Friday events, which occur weekly from 10am-12pm and 1-4pm. More information can be found on the organization’s website at ccat.humboldt.edu/ and Instagram @ccat.humboldt.

  • Geology students dig deep during 20th annual geology expedition

    Geology students dig deep during 20th annual geology expedition

    by Harrison Smith

    Since 2003, the CPH Geology department has been bringing students to various geologically significant sites across the western US during a marathon spring break field trip. This year marked the twentieth anniversary of Geology 110: Field Geology of the Western United States, uninterrupted by even the pandemic, and the retirement of veteran geology professor Mark Hemphill-Haley.

    At 8am on March 11, all twenty members of the 2023 Geology 110 expedition met at Van Matre Hall weighed down with our camping gear to load into the four vehicles that would be our homes for the next two solid days as we drove to Death Valley.

    The Bonanza King Formation is a massive bed of carbonate rock that constitutes much of the boundary between Nevada and California. It is visible in many places across both states, but at Point of Rocks, it dominates the landscape. There, tilted beds of Bonanza King carbonate cut through the terrain like the ribs of a dead giant, draped in loose alluvium that slants down to the desert flats. 

    The footing on the ridge was treacherous. Skree slid under my feet as I moved up the slope, conscious only of the $500 Brunton Compass in the case at my belt and the possibility that I might drop it in front of everyone. I looked down, and, deciding that the bed at my feet was good enough, knelt to remove the Brunton from my belt case. In the protection of my big straw hat, I carefully lay the edge of the compass flush on the top of the carbonate bed, tilting it this way and that in a futile attempt to find the striking angle of the bed. It was exhilarating to finally be practicing a geology skill in the field. We were learning to measure the striking angle of a rock bed, which is the compass heading at which it cuts the ground, and I was determined to find it myself. In conjunction with the dip, which is the angle at which the bed descends into the ground, strike-dip measurements of rock beds and faults provide a picture of what’s going on under the surface. Finally, I set aside my pride and looked around to find Michelle Robinson, geology alum extraordinaire, who was down the ridge helping another student. 

    “Michelle, can you help me with this strike?” She smiled. Of course– this trip was all about learning. Each one of the students I spoke to about our experiences on the 2023 Death Valley trip said something similar. 

    “It was a little difficult to ask questions, but as soon as you understand that no one is judging you, it’s a perfect open environment,” third year geoscience student Jane Martinez said. 

    My experience was the same– at first, I felt in awe of the older students. They seemed to know exactly which questions to ask at each of the stops we made along the way, but I never felt too intimidated to ask my own questions. Every interaction was a reminder that science is not a competition, but a collaboration. 

    “At first, I was pretty shy too, but I just liked the fact that some of my upperclassmen helped me out with terms that I didn’t know and they were always giving me information on the simplest questions, and I really appreciated that,” said Daniel Abel, a third year geology major. “If I’m with someone new, I’m going to help them out as much as I can with the information that I have, so that they can get better and smarter with geology.”

    This trip was an extremely valuable experience in that it allowed geology students to form bonds with their peers.

    “I feel like I made a lot of really good friends over the trip and it’s kind of hard to do that sometimes,” Abel said. “I really appreciate that.” 

    Mark Hemphill-Haley has been associated with Humboldt’s geology department for decades, first as a student and then as a professor. 

    “The thing that excited me about geology when I first came to Humboldt was the enthusiasm that the department and the students shared about learning geology, and the depth of knowledge of the faculty and their excitement,” Hemphill-Haley said. “I think at Humboldt students in general are a little different than some other universities. You know, it’s a little harder to live here in some ways. So I feel like people that are here really want to get their life’s worth out of the programs. And so I just think that the students are special.”

    Trips like Geology 110 and the connections made during those trips are what make Humboldt special. “The thing that I’ve noticed from when I was an undergrad to students now is, we’re still the same,” Hemphill-Haley said.

  • Indigenous activism brings down Klamath dams

    Indigenous activism brings down Klamath dams

    Harrison Smith

    The Klamath salmon have been granted a reprieve. After decades of activism by Indigenous people, four of the six dams on the Klamath are finally coming down. Pacificorp, corporate owner of the dams slated for removal, was denied a renewal of their operating license by the Federal Energy Regulatory Commission in November of last year.

    The Klamath Basin is one of the largest watersheds in the continental United States. Melting snow in Oregon’s Cascade Range mixes with runoff from Crater Lake, frigid waters flowing south and west to fill Klamath Lake. In past years, Klamath Lake’s cold, high-nutrient water tumbled to the coast, providing habitat for dozens of salmonid species.  

    Until the dams were built. 

    “They haven’t had any salmon in over 100 years,” said Regina Chichizola, director of Save California Salmon. “The Karuk Tribe no longer has spring salmon even for their spring salmon ceremonies.” 

    Salmonid populations in the Klamath Basin have seen a staggering 95% decline since Copco 1 was built in 1918 and those numbers only continued to fall as the basin was strangled by the next three dams. 400 miles of river habitat have been either partially or completely blocked to fish passage, and Klamath salmonids were on the path to extinction. 

    “Having that acknowledgement is a really big deal, because it’s not just acknowledging that this is a bad deal the river’s been given, but also us as well,” said Brook Thompson, restoration engineer for the Yurok tribe. “And that our voice does matter. Sometimes when you protest, in activism work, it feels like nothing’s gonna change and no one is hearing you, and that’s the case; it feels like we were finally heard.”

     Thompson is a descendent of both Yurok and Karuk tribes, and a Ph.D. student. 

    There are currently four dams on the Klamath river. Copco 2 (1925) is slated for removal this year, followed by Copco 1 (1918), J.C. Boyle (1958), and Iron Gate (1964).

    Negative impacts

    The negative effects of the Klamath dams are numerous and interconnected. By slowing down the river, the dams allow the water to heat up in the sun. 

    “With that warm water, you get less dissolved oxygen, which the fish need to breathe,” said Thompson. “You get increased blue green algae blooms, which when they die, they take up dissolved oxygen, which, again, means less dissolved oxygen for the fish.” 

    The dams also cause the river to cut into the riverbed, by locking its flow into a narrow channel and preventing it from connecting to the wider floodplain.

    On September 19th, 2002, dead Chinook salmon began washing up on the banks of the Klamath. During the next week, over 60,000 adult Chinook would wash up on the banks of the river like a rotting carpet.

    “It was the day after one of the ceremonies,” said Thompson, who was present at the catastrophe as a child. “I was the same size as the salmon I saw the bodies of on the shore.” 

    This can be directly linked to the dams’ effects on the Klamath. The closely-packed conditions of the migrating Chinook and high water temperatures were a perfect environment for parasite Ichthyopthirius multifilis and bacteria Flavobacter columnare, which together ravaged the salmon population. Low flow from Iron Gate dam, due to irrigation runoff, was found to be a primary cause in the Fish Kill. 

    Indigenous sovereignty 

    The Yurok, Karuk, Hoopa, and Klamath tribes have been fighting for their rights to river governance and access for over a century. 

    “We’re fighting for our cultural sovereignty, making sure that we’re upholding our responsibility as human beings to make sure that we’re making this world a livable space for not just humans,” said Charley Reed, education director for Save California Salmon and descendent of the Yurok, Karuk, and Hoopa tribes. 

    Before colonization, Indigenous people depended on the Klamath as a primary source of food, with an average salmon intake of 450 pounds of fish per person per year. Today, that number has dropped to under a pound. 

    Activism

    In 1973, Yurok community leader ‘Aawokw Raymond Mattz took the issue of Yurok fishing rights to the U.S. Supreme Court and won. However, state and federal agencies continued to crack down on Indigenous fishing well into the 1970s. This sparked a period of protest now called the Fish Wars. Anti-dam protests continued sporadically for decades, but gained renewed purpose after the 2002 Fish Kill, according to Reed.

    “To get the U.S. to do things you have to sue them,” Thompson said. “That’s actually how we got the fishing rights back from my neighbor when I was a kid.”

    In the 2000s, dam protesters spent one week of every month traveling to protest. Reed’s father was deeply involved with the movement for decades. Protest efforts in the wake of the Fish Kill led to the founding of Save California Salmon, a nonprofit organization founded, operated, and led by Indigenous people. SCS along with other groups focused the energies of the Klamath Tribal communities onto the dams. In 2004, dam owner Pacificorp filed to relicense the four dams on the Klamath. This provided an initial objective for the activists—stop the relicensing. 

    The activists took a multi-pronged approach to the campaign for the dams’ removal. They applied public pressure on lawmakers and dam owners, as well as working with state and federal officials. 

    Activists traveled to Scotland in 2004 to demonstrate against the parent company of Pacificorp, Scottish Power, during a shareholders meeting. In 2005, Scottish Power sold Pacificorp to Berkshire Hathaway and activists continued the pressure.

    “2006 or 2007 was the first year we went to the Berkshire Hathaway shareholders meetings,” Chichizola said. “And even before that, we went to Pacificorp headquarters in Portland…. A big part of it was the community pressure for sure. Every step of the way, the community was there.”

    In response to the continued activism, the Berkshire Hathaway board changed the rules of their Q&A sessions in 2008 to forbid questions about the Klamath dams. 

    Activists succeeded in lobbying the California and Oregon governments to require extensive renovations of the dams before they could be relicensed — a major victory. The Klamath Basin Restoration Agreement (KBRA) between the states would have demolished the dams years ago and reallocated water for irrigation. It was killed in the house by republican congressmen Doug Lamalfa and Greg Walden. 

    In 2016, parts of the KBRA were salvaged to create the Klamath Hydroelectric Settlement Agreement. The KHSA was passed without congressional approval, but its passage was followed by another period of bureaucratic snarls that were only resolved last year. After relentless pressure from all sides, it proved far more expensive for Pacificorp to relicense the dams than to remove them. 

    In November of 2022, the Federal Energy Regulatory Commission denied Pacificorp’s license to operate its Klamath River dams, and the dams came under the jurisdiction of the Klamath River Renewal Corporation (KRRC). FERC credited Tribal activism for the government’s decision to decline Pacificorp’s license renewal.

    Demolition and restoration

    Copco 2 is scheduled to be demolished this year, but much restoration work remains to be done before the basin is whole again.

    Extensive preparation must be completed on more than 400 miles of river that have been cut off from the greater watershed for the better part of a century, mostly on the lower river. The KRRC was created to carry out the restoration work. 

    “We’ve been collecting seeds for the last few years and then we’re growing plants,” Thompson said. “These native plant species will have a chance to take hold before invasives come in.” 

    Work must also be done to reconnect the river to the system of ponds and tributaries which fed it historically. All this will eventually restore habitat and favorable conditions for salmonids, according to Thompson.

    “All that habitat needs to be restored and that’s going to be creating more woodfill, creating different types of flow, so [salmon] can chill out in slower ponds or move up faster streams and try to get different types of food,” said Thompson.

    The Elwha Dam removal in Washington could give some insight into the Klamath’s future. 

    “As soon as a year after the Elwha dam removal, which happened just over 10 years ago, you saw salmon that were returning above the dam to breed, which is kind of crazy, because they haven’t been going there for generations,” Thompson said.

    For Reed, the victory felt bittersweet. It comes after many long decades of teeth-pulling effort, marked by the passage of loved ones and community members — stymied by corporate and governmental roadblocks.

     “There’s so many people who weren’t there that day that had passed on, but were very much a part of that effort in those early years,” Reed said. “If it wasn’t for them, it’d be really hard to imagine how we would have kept that momentum going, how we would have kept up the fight. It’s very much intergenerational.” 

    Reed plans to teach his daughter to fish when she’s old enough. By then, restoration efforts will be well underway.

  • Aftershock: the nuance of Humboldt geology

    Aftershock: the nuance of Humboldt geology

    by Harrison Smith

    Hey – did you feel it? That little jolt? The coffee on your desk is even rippling! I think we just felt an aftershock! 

    For some, aftershocks are a fun little jolt that give you something to talk about in line at Los Bagels. For others, they are terrifying reminders of Humboldt’s earthquake vulnerability. 

    For almost a month following the Dec. 20 earthquake that devastated parts of the county, over 80 aftershocks of magnitude 2.5 or greater have gently shaken Humboldt- most too small to be felt. Large earthquakes in fault-prone areas like Humboldt may change the stresses on adjacent faults. 

    “The kind of earthquake that fault produced, with that kind of slip, can produce a pattern of stresses which, in some instances can promote a nearby fault to be closer to failing,” said Dr Mark Hemphill-Haley, a geology professor at Cal Poly Humboldt.

    Some shifts release stress to delay an earthquake, while some increase stress. This can trigger new movement as the fault system searches for a new equilibrium. The pattern of aftershocks can provide important clues into the state of the fault system. 

    “From just the 2.5s, you can kind of get an idea of how they ruptured along the subduction zone,” said John Bellini, geophysicist at the USGS National Earthquake Information Center. 

    However, accurate triangulation of the Ferndale quake’s epicenter and those of its aftershocks is complicated by the fact that the fault system lies largely offshore. 

    “Because all of the stations are onshore and the main shock was just offshore, you don’t get as meaningful distribution,” said Bellini.

    Judging from the distribution of the aftershocks, one might think that they followed East-Northeast running faults. However, data is often deceptive. 

    “If you look at the trends of the faults, they are Southeast to Northwest,” said Bellini. “This misleading artifact of the map is due to imprecision in triangulation- in order to locate the epicenter of an earthquake, it must be recorded from three different seismic stations.” 

    The more surrounded the earthquake is by seismic stations, the greater one’s ability to measure it precisely. Because the closest ‘western’ seismic stations are in Hawaii, precise observation of seismic activity off the Humboldt coast is difficult.

    “Most of the stations for most of those quakes are going to be to the east, with nothing to the west for most of them… when that happens, the error ellipsoid for them is going to be stretched in an east-west direction,” said Bellini.

    Humboldt County sits at the very south tip of the Cascadia subduction zone, where the Gorda/Juan de Fuca, Pacific and North American tectonic plates come together in a geologically complex region called a triple junction. 

    The difficulty of studying the complex tectonic interactions at this triple junction is compounded by the fact that it lies half offshore, however new developments in geology have lifted the veil on offshore tectonics. 

    Last summer, researchers from Cal Poly Humboldt’s geology department along with researchers from the US Geological Survey, UC Berkeley, and University of Washington installed over 40 seismometers along an optical fiber cable that runs from Aracata to Eureka. Instruments connected to the optical fiber along with the seismometers provided high resolution about the local seismicity. The instruments were removed after their testing period was complete, but they were reinstalled immediately in the aftermath of the Dec 20, 2022 Ferndale earthquake. 

    The use of fiber optic cables for monitoring earthquakes is very recent, but a huge development for geology in areas like Humboldt.

     “We’ve already recorded more than a hundred aftershocks associated with that recent quake,” said Dr. Hemphill-Haley.

  • Comet visible from Humboldt County

    by Alina Ferguson

    A comet is a ball of ice which burns up when it passes the sun. That burn-off is what is seen by the human eye. On February 1, the green comet known as ​​C/2022 E3 (ZTF) was at its closest and able to be seen by the naked eye, though it was 26 million miles from Earth. 


    Though it was visible in the Northern Hemisphere, the conditions in Humboldt were not optimal for viewing. Many may have had a hard time seeing this comet, referred to as C/2022, due to fog and pollution in the sky. For those who missed it on Feb. 1, it was still visible by telescope or binoculars Feb. 2. 

    Comets have an elliptical orbit. They spin close to the sun and then away from it, interacting with the gravity of other objects along the way. When they pass by the sun, they sometimes become visible from Earth. What we see is the comet releasing gasses.

    Comets are from the outer solar system and they spend most of their lives very far from the sun. Tyler Mitchell, a physics professor at Cal Poly Humboldt, refers to them as, “little time capsules of frozen ices and a variety of different types of dust, like carbon and silicates.” 

    C/2022 is a green comet. “The color comes from two carbon atoms stuck together,” said Mitchell. “The tails of most comets are yellow.”

    To Tanner B. Hooven, a student and member of the Cal Poly Humboldt Astronomy Club, C/2022 is a reminder of Earth’s past. We are the first people since the recording of time to see this comet.

    “This comet is special because of its orbital period, or the time it takes to make one full journey around the sun, is approximately 50,000 years according to Nasa’s Jet Propulsion Laboratory,” Hooven said. “The last time this comet approached its perigee was at a time in which Neanderthals were still roaming the earth.” 

    Comets are sometimes called “dirty ice balls”, though they should be referred to as an icy dirt ball, given their respective ratios. Comets can become asteroids, which are referred to as “dormant comets.” 

    When identifying comets, or asteroids, astronomers look for what is essentially a “photobomb” and streak that was not previously there, or a bright shining star that was not before visible, according to Mitchell. 

    This comet is currently on its way out of the inner solar system. It will take months for it to fade from our view. 

    “It is likely this comet will continue to orbit the sun for millions of years until the off-gassing process subsides due to a lack of ice left in the comet,” Hooven said.

  • NASA Engineer Jessica Bowles-Martinez speaks to students on Humboldt campus

    NASA Engineer Jessica Bowles-Martinez speaks to students on Humboldt campus

    by August Linton

    Jessica Bowles-Martinez, an ex-NASA engineer and “systems engineer, aka science wrangler,” spoke to Cal Poly Humboldt students on Monday. About 20 attendees gathered in Science A 475, sipping coffee and hot chocolate as late-afternoon gray rainy light filtered through the windows.

    The seminar, “Wrangling Scientists and Engineers to Make Something Awesome – Systems Engineering” was put on by the CPH Physics Department. It focused on Bowles-Martinez’s role in various NASA projects, defining what a systems engineer’s role is in these exacting and large-scale endeavors. 

    After graduating high school in Fresno, California, Bowles-Martinez attended MIT where she majored in electrical engineering, computer science, and media studies.

    In her 13 years working at NASA’s Pasadena-based Jet Propulsion Laboratory (JPL) Bowles-Martinez was on the team for many high-profile projects. She worked on New Horizons, which was the first probe sent to explore Pluto up close, as well as the OPALS (Optical Payload for Lasercomm Science) laser data transfer project on the ISS. Her other projects include the Perseverance Mars rover and the Europa Clipper, which will fly by Jupiter’s fourth-largest satellite and assess it for markers of life. 

    As a systems engineer, Bowles-Martinez’s role on projects is to facilitate communication and collaboration between the science team, engineering team, and the team that actually builds the finished design. 

    “It’s not just checking the boxes, it’s about ‘does it all work together?’” she said. 

    There were many problems which the OPALS team had to contend with to ensure a successful outcome, according to Bowles-Martinez. The entire project, which was attached to the outside of the ISS, was a test of an experimental method of data transfer, which would add the capability to send high-res video from the station. The laser used on the module was potentially dangerous to the astronauts on board the ISS, so there needed to be extensive safety measures around its deployment. 

    “Because this laser is class 4, if an astronaut looked at it they would go blind. So we had to figure out how you make a system that will be safe enough to have it be on the space station and shoot this laser down to Earth; all the safety controls are there,” Bowles-Martinez said. “My job is to be in the middle of everyone on that type of stuff.”

    As a systems engineer on the Perseverance rover, Bowles-Martinez worked on the systems which brought the rover safely down from orbit onto the planet’s surface, as well as the systems which launched the Ingenuity Mars helicopter from the main body of the rover. 

    To physics and engineering students hoping for a career in NASA, Bowles-Martinez stressed the importance of internships and especially programming experience. 

    Systems engineering is a little-known field, but absolutely essential to every NASA endeavor. 

    “It’s a really intricate science dance, almost,” Bowles-Martinez said.

  • Sea level rise threatens Humboldt, local government stalls

    Sea level rise threatens Humboldt, local government stalls

    by August Linton

    The edges of Humboldt Bay are on the verge of being overrun by the sea. It laps at the boundaries of Highway 101, surrounds the Arcata Marsh, and sneaks around the corners of low-lying industrial areas in Eureka. 

    SINKING SHORELINE

    Humboldt’s location at the end of the Cascadia Subduction Zone makes the area more vulnerable to sea level rise than any other location on the California coast. Due to its position in a very active tectonic area and the specific activity of the surrounding plates, the Humboldt County region is steadily sinking, or subsiding. 

    The Humboldt Bay Vertical Reference System Working Group is a research group focused on identifying geology’s role in Humboldt Bay sea level rise. In a 2017 report, they found that land subsidence contributes to sea level rise 2 to 3 times more in Humboldt County than anywhere else in California. Of the 18 inch rise in sea levels that has occurred locally in the past century, an estimated 50% is due to tectonic subsidence.

    “The ocean isn’t rising any faster off of our coast than it is down in San Francisco, but we have subsidence that the rest of California doesn’t have,” said environmental planning consultant Aldaron Laird. 

    Laird has been an essential part of local sea level rise risk assessment and adaptation planning over the last decade, consulting with Humboldt County and various local districts. 

    ADAPTATION PLANNING

    Humboldt County has commissioned many reports which assess the risk that sea level rise poses to infrastructure and communities. These contextualize what different levels of sea level rise will mean, and suggest possible adaptation measures. However, the reports do not implement the adaptation measures.

    The most recent grant-funded project to tackle this issue concluded in 2019, yet none of the recommendations from that, or any other report, have been implemented. 

    An area that the reports do not touch on is the potential for industrial contamination in the bay as sea level rise reaches new areas.

    In her career as an environmental advocate, Jennifer Kalt has observed the local government’s lackluster reaction to the threat of sea level rise for years. 

    “What I have seen as a repeating theme is a lot of local jurisdictions getting grant money to develop plans and then there isn’t a plan,” said Kalt. “It’s a little depressing to see so much planning lead to nothing.”

    Michael Richardson is a supervising planner of long range planning in the Humboldt County Planning and Building Department, which is responsible for sea level rise adaptation planning. He said that the county would like to decide on terms of collaboration with other local jurisdictions before they plan to implement any sea level rise adaptation measures. Simply put, they don’t have immediate plans to do anything specific.

    “There would be a different process to go forward with getting the cities and the county on the same page and whatever agreements need to be made,” said Richardson. “What that plan looks like is what we’re still figuring out.”

    Kalt doesn’t think that the pace at which the government is moving on this issue will make a difference in time. In addition to protecting residential areas, she said that their focus should be on relocating key infrastructure. 

    “I’m concerned that a lot of the agencies that need to address these problems, there’s not a lot of political will to do what needs to be done,” said Kalt.

    There are many organizations with an interest in adapting Humboldt Bay to meet the challenge of sea level rise. The Coastal Commission, CalTrans, Humboldt County, local city governments, and even the state government of California all hold potential responsibility for the threatened areas. Kalt doesn’t see any of them doing anything to prepare.

    “It’s a Humboldt County pastime to finger-point,” said Kalt.

    A recent report released as part of the county’s Humboldt Bay Sea Level Rise Regional Planning Feasibility Study extensively details what theoretical responsibility a variety of local, state, and federal jurisdictions would have to combat sea level rise, but does not lay out a plan for collaboration. A further report is expected to be published before the end of 2022, recommending a strategy for collaboration.

    If nothing is done to adapt to the changing coastline, life around Humboldt Bay will look very different in 50 years. Infrastructure-rich areas will be reclaimed by the tide, and local government and utilities companies alike will have to find ways to work with the new bay. It is also worth considering that any adaptation measures will likely take significant time and resources to complete given their cost and scale.

    KING SALMON

    One of the first areas in Humboldt to be substantially impacted by sea level rise is the unincorporated community of King Salmon. This oceanside community is located across from the mouth of Humboldt Bay just south of Eureka, exposing it to the full brunt of tidal forces. Sunbleached houses, mobile homes, and a few small businesses line canals. It is located only 3 feet above sea level. 

    In early January 2022, there was a flooding event in King Salmon caused by king tides coinciding with the rain and high winds from a storm. Photos depict residents kayaking down the street or wading shin-deep in water. Little structural damage was done, but it was obvious that King Salmon is at extreme risk as sea levels continue to rise. 

    Parts of the community are only accessible via a single bridge on King Salmon avenue. Any tide which overtook this could leave residents with no method of escape. In a 2022 Humboldt County Civil Grand Jury report, this is predicted to occur within 3 feet of sea level rise, possible as soon as 2070.

    INFRASTRUCTURE

    Other significant infrastructure endangered by the amount of sea level rise listed in the report include PG&E’s Humboldt Bay Power Plant (HBPP) complex, Highway 101 as it traverses the bay, and water and electrical transmission lines. Several sites contaminated with industrial waste will also be reached by tides at this level.. 

    According to a report authored by Laird, 1.6 feet of sea level rise, possible by 2040, will put King Salmon underwater during king tides. Sea level rise of 3.3 feet, predicted to occur by 2065, will cause the tides to overtake most of the area daily. 

    According to Laird, the most pressing threat to King Salmon is whether utilities will continue to be available to its residents. “It only takes one utility to stop providing service and you wouldn’t be able to live there anymore,” he said. 

    PG&E’s Humboldt Bay Generating Station, located in King Salmon, supplies power to around 67,000 people. It is predicted to be threatened by king tides by 2065. The plant will have to be relocated or otherwise protected from the tides in the near future if it is to continue supplying power to Humboldt County.

    The Humboldt Bay Independent Spent Fuel Storage Installation, a nuclear waste storage facility, is located on the HBPP campus. It houses the spent fuel from the Bay Generating Station’s nuclear predecessor. There are currently no plans to relocate the spent nuclear fuel stored there.

    HERE AND NOW

    Participants in the Humboldt Baykeeper’s King Tides Photo Initiative have found evidence of high water levels affecting Humboldt County here and now. Founded in 2004, Humboldt Baykeeper is an advocacy organization which focuses on preserving coastal resources around the bay. They monitor levels of contaminants present in the bay, assess new industrial developments, and catalog the effects of sea level rise. 

    The King Tides Photo Initiative encourages members of the community to document areas inundated by high tide levels. In many of  these photos, residential areas around the bay are actively being overrun by the sea. Some of the images aggregated on Baykeeper’s Facebook page show the Highway 255 bridge over Mad River Slough nearly overtopped, Jackson Ranch Road in the Arcata Bottoms covered with water, and waves crashing over a parking lot at the Arcata Marsh.

    The Highway 101 corridor is one of the areas where tidal inundation is starkly visible. Despite the bay’s encroachment, there are ongoing plans to extend the Humboldt Bay Trail along that same strip to reach Eureka. 

    DIKED SHORELINE

    Humboldt County and the Eel River Delta are uniquely vulnerable to sea level rise. The historical legacy of diking the shoreline in order to create more usable land has led to a large concentration of critical infrastructure in former salt marsh lands, according to Laird.

    A large portion of Humboldt County’s critical infrastructure is concentrated in former salt marsh lands. This land is made accessible and flood-proofed by a system of dikes which will not stand up to sea level rise.

    “Highway 101, Highway 255, municipal water lines, wastewater treatment lines, natural gas lines, optical fiber lines; all of this infrastructure is built on that former tideland which is prevented from saltwater inundation only by the diked shoreline,” said Laird. 

    The location of this infrastructure in former tidelands means that a breach in any one dike could result in the entire area being flooded. “We don’t have to wait for sea level rise to see the impacts of reclaiming the diked former tidelands,” said Laird. 

    Even if every dike around the bay holds against today’s water levels, they will be overtopped by 2 to 3 feet of sea level rise by 2040 at the earliest, and 2060 at the latest. Additionally, there is no bay-wide district in charge of maintaining the dikes. Instead, over 100 shoreline parcels are individually managed by local jurisdictions. 

    It costs millions of dollars to rebuild even one mile of diked shoreline, and the raw materials to rebuild are not readily available in the quantities that would be needed.

    “If we can’t address these and do anything about it, I think the first thing that’s going to happen is the dikes…they’re going to fail,” said Laird. “They’re going to breach and the bay is going to reclaim the 7 to 9 thousand acres of tide lands that used to be part of it. It’s the areas that we gobbled up from the bay over a century ago, those are the ones that are most vulnerable.”

  • The Campus Collector 

    The Campus Collector 

    by Alana Hackman

    Sunday mornings, you’ll find most college students tucked away in their beds catching up on sleep, or maybe packing away their notes for a long day at the library.  Nearly every Sunday morning you can find Heather Davis perusing campus bushes and trees; wielding red Felco pruners, or “snips” as she likes to call them, in one hand and a clump of wrinkly brown paper grocery bags in the other. 

    Davis isn’t going on a big grocery trip or planning to do any landscaping, rather she is harvesting plant specimens around campus for botany majors and BOT 350 (Plant Taxonomy) students. Davis is the plant collector for Dr. Oscar Vargas’s Plant Taxonomy class this year. 

    “The labs are Monday, Tuesday, Wednesday, and Thursday,” said Davis. “So I usually collect Sunday for Monday and Tuesday labs and then I collect Tuesday for Wednesday and Thursday labs. 

    With over 120 students enrolled in plant taxonomy this semester, Davis has her hands full nearly every week. On top of being a botany student herself, the Tulsa, Oklahoma native is balancing her two children with the 16 units she’s taking this semester. She made her way to Humboldt county nearly a decade ago in the pursuit of organic farming and decided to start studying for her degree in botany in 2019.

    “I was really interested in organic farming and more natural practices, everything in the Midwest is super mono-cropped and sprayed and really gnarly,” said Davis. “A friend was here in Willow Creek working for a farmer and they were like you should come check it out and like, be a part of the community here so we came out here and worked for that farmer for two seasons.”  

    Davis’s passion for plant collecting shows. She comes to Science D nearly every Sunday around 9:30 a.m, bringing along her infectious smile and a bright blue stainless steel mug decorated with an artistic owl sticker. There are dried leaves carefully placed in the back of her iPhone case, and she sports a black long sleeve shirt printed with various weeds and flowers as her uniform of choice. 

    Davis usually begins her collection process by making her way into the Plant Taxonomy storage room located in room 153 in Science D, to prepare large clear bins with moist paper towels for collection storage. The room has rows of labeled jars filled with dried leaves, stems, and clippings. Some are simple masking tape categories, but there are also some printed skulls and crossbones, warning handlers of the plant’s poisonous properties. 

    Davis was inspired by her previous botany professors to pursue this job, Dr. Oscar Vargas and Stefani Brandt. She was especially interested after taking the plant taxonomy lab for herself.

    “Both of them are amazing instructors, they were super inspiring, Stephanie especially,” said Davis. “I was like ‘aw I wanna be a part of this but I didn’t realize there was a plant collector until they offered the job up to the students in the class”

    Davis isn’t afraid to dive headfirst into her collecting job, she haphazardly snips away different flowers and shrubs surrounding the Natural Resources building and College Creek Marketplace. She climbs trees to collect specific branches and tastes the tart huckleberries around campus before collecting them for storage. Most of her collecting is done on campus, but she sometimes can make her way up to Trinidad for specific specimens.

    “I collect all over the place,” said Davis. “Campus mostly cause there’s a lot of really awesome plants already growing here but there’s a few like invasive or cultivars that they need for the lab, so I’ll end up going to the marsh or sometimes random people’s yards around town, a little reconnaissance.”

    Davis appreciates this position for allowing her to explore the nooks and crannies on campus and doesn’t seem to mind the business it brings into her already hectic schedule of being a mom and student in STEM.

    “I think it’s really cool to walk around campus and see how many plants are here. Before I started the position I was like ‘it’s going to be so hard to find all these plants, like campus is all Rhododendrons,’ said Davis. “Then I started walking around and these plants are everywhere, it’s so cool to be like ‘Oh Hey I didn’t see you before.’” 

    Davis also mentioned sharing her love of plants with her children as well.

    “My kids get involved, if you come in here you’ll definitely see them walking around with giant plants, said Davis. “They really love it, they’re inspired by science so it’s really fun to bring them in, they can look at the microscopes and see all the jarred plant specimens in the prep room and stuff.”

    Davis is the embodiment of finding joy in your career. Her bubbly personality and vast knowledge of native plants, grasses, and even weeds is hard to ignore in any conversation with her. She’s become an expert at balancing work and play in her jam packed schedule.

    “It’s definitely a ton of work being a botany major or a stem major in general but it’s so worth it,” said Davis. “I think it’s really cool to see that there’s plant collecting happening, and that there are these really fun jobs that you can do on campus and I’m inspired and love it.”

  • Free Radicals chemistry club has fun with science

    Free Radicals chemistry club has fun with science

    by Dezmond Remington

    On Sep. 20 in room 564 of the science A building, approximately 20 people ingested a toxic chemical known as propylthiouracil. It was not a mass suicide attempt. It was not a Jonestown re-enactment, nor were they getting high. It was a meeting of the Humboldt chemistry club.

    Propylthiouracil is a chemical used to test if an individual is especially sensitive to taste, someone known as a “supertaster.” If the paper containing the substance was especially bitter, then chances are good that person is a supertaster. The members of the Free Radicals, the chemistry club on campus, were testing if they were supertasters. 

    “I just put poison on my tongue, so I guess I’m ok with anything,” laughed member Angela Takahara. 

    If the energy of the Free Radicals could be put into one quote, that would probably be it. 

    “People. That’s the best part,” club president Jack McLaughlin said. “It’s probably the best place for chemistry majors and a lot of other majors to socialize. It’s just a great community to have and to talk to, because not a lot of other people really understand chemistry…it’s nice to have people who understand you, where you don’t have to explain every other concept.”

    McLaughlin joined the club his freshman year, and hasn’t regretted it once. He said it’s an excellent way to get connected with important resources and more experienced students, as well as guest speakers who are in the industry or are teaching currently. 

    “It really helps guide newer students and even sophomores, juniors, and such towards figuring out what to do with their chemistry degree,” McLaughlin said, “And also how to make the most out of college.”

    The Free Radicals aren’t only open to those working on chemistry degrees, however. Shay Konradsdottir, the club’s Social Director and Events Coordinator, is a molecular biology and computer science double major, with only a minor in chemistry. Her favorite part of being in the club is putting events on, such as a tie-dye event the club held last semester to showcase the science of colors. 

    “As social coordinator here, I really enjoy planning the events and making fun things,” Konradsdottir said. “Making this stuff, and sharing this interest in the sciences and interest in chemistry in a way that’s not just ‘here’s what the reactions are called.’”

    And it is that interest in chemistry that binds all of the members together. McLaughlin said the nature of chemistry being everywhere was the appeal, and how it oftentimes was the key to understanding so much of life. 

    “[Chemistry] is like the building blocks of the universe,” McLaughlin said. “…I feel like I can pursue all of my passions for environmentalism and such through chemistry.”

    Senior Sam Emerson, attending his first meeting at the Chemistry Club, holds a similar viewpoint. 

    “I like figuring out what makes the universe run the way it does,” Emerson said. “It feels like getting to know the game engine behind everything…I’ve always thought life was really fascinating and that although the universe prefers disorder, there are certain, random spins of chemicals that happen to make order out of nothing.”

    Konradsdottir, who Emerson credits with convincing him to join the Free Radicals, has a much more personal background with science and how it interacts with their lives. She was diagnosed with Type 1 diabetes when she was young, and was a subject in medical studies. It was a defining moment in her life, she said, and it inspired her to become a doctor and help people. Eventually, she became interested in coding, and that led her to where she is today; gunning for an MD-PhD and potentially opening her own free clinic or making more effective medical diagnostic tools. 

    “I felt really awful about when I’ve heard stories from my friends or even some family members that were prevented from doing the things they loved doing because they got an injury or they got sick,” Konradsdottir said. “I myself, being a diabetic, there are lots of things I missed out on because I’m a diabetic, so being able to catch those things and prevent them from happening–that’s interesting to me.”

    Being the club events coordinator, Konradsdottir hopes to share that fascination with the rest of campus. Last semester, she went on a field trip where she got to make a pleasant-smelling chemical, but wasn’t allowed to take any home. If the club had unlimited money, she would hold an event where anyone could show up, get a free lab coat and goggles, and concoct something similar to what she got to make–with the difference being they would get to keep it. 

    “It’s fun! We just do fun stuff here,” McLaughlin said. “It’s not like actual work…you don’t have to understand anything about chemistry, so long as you show up with a good attitude.”

  • Mycologists club: Fun-gis in the forest

    Mycologists club: Fun-gis in the forest

    by Alina Ferguson

    Mycology is a very young science, a baby in fact. Up until 1969, Fungi did not even have their own kingdom, as they do now, but were technically considered to be plants. Mushrooms are not plants, contrary to what many may believe.

    Some of the most prominent and common mushrooms in Humboldt are actually the edible ones such as the King Bolete and the Pacific Golden Chanterelle. According to Cal Poly Humboldt Mycology Club President Jack Mccann both of these mushrooms are very delicious. 

    Mccann said what brought him to the Mycology club was cooking. 

    “As a mushroom person I really love to cook,” said Mccann. “I think I like to cook first, that’s part of what got me into mushrooms, it’s just cause it opens a whole new world of food,” said Mccann.

    The club holds weekly mushroom hikes on Fridays, which are open to everybody regardless of club membership. This is a chance for the hikers to go out and experience the forest through a mycologist’s perspective.  Every alternating Friday, they host workshops and guest lecturers. These meetings are more targeted towards people who already know about fungi. 

    The Mycology club is having a two day DNA barcoding workshop on September 30th-October 1, 2022. The club members will learn about the process used to genetically test the species of a mushroom. This process can often lead to the discovery of new species. During the workshop, club members will see if there is a difference between different mushrooms on a genetic level. 

    “We’re gonna borrow a lab and, basically in a pretty sterile environment you separate the mushroom using some primers, seek out the genes you’re looking for and then amplify those genes so you could actually read them,” said Mccan.  

    Essentially, what Mccan said is that the club will be collecting mushrooms and then using their DNA to see if there are any genetic differences between species of mushrooms. 

    “The machine, known as a thermal cycler, gives you a visual representation of what it looks like, you compare it to what it’s supposed to look like, what you’re expecting.”
    All of the prep work will be done at the two day workshop. This includes the collection, the DNA sequencing and the comparison of the DNA. 

    Then, their guest speaker Damon Tighe will get back to them with the results. Tighe is a mycologist working out of Oakland and is working with the Company Bio-Rad. He is driving into Humboldt with all the equipment.

    The logging industry has a negative impact on mushroom culture. Unlike foragers, who simply take the ‘extension’ so to speak, of the fungi, what is known as the fruiting bodies, loggers do damage with their machines that dig into the ground. 

    Logging practices harm the mycelium, the other part of the fungus’ body.  Mycelium is a root-like network that grows under the soil, it is what produces the fruiting bodies we know as mushrooms. According to Tighe, mycelium is just the vegetative state of a fungus. 

    Treasurer Sam Parker said he was drawn to the foraging aspect of Mycology. 

    “I first learned to do that when I was around eight with morels, and I just love being out in the woods,” said Parker “Mushrooms are a very diverse lifeform and I feel like they just kinda tie everything together, and I just think they are just interesting to learn about,” said Parker.

  • Green Campus Team shares resources on fun sustainability

    by Oden Taylor

    For Amber Chung, sustainability is everything. As an environmental science management major and the student leader of Cal Poly Humboldt’s Green Campus Team, Chung says she has been in love with the environment since she was a kid. 

    She said watching and reading “The Lorax” by Dr. Seuss opened her eyes as a child to the need for sustainability.  

    “I really saw for the first time like wow, like what we do literally does matter. It can change the whole environment like it did there,” Chung said. “Now that I’ve gotten older, I’ve realized that sustainability is such a wide concept, it has to be in everything for everything else to work. If you don’t center sustainability, you’re not really going to get anywhere with anything else, because it’s not going to last long term.”

    As a branch of the Office of Sustainability, the Green Campus Team is an organization that consists of five student employees and one staff advisor. Their goal is to encourage everyone on campus to center sustainability in everything they do.

    The team provides educational materials and advice for groups on campus on how to be as sustainable as possible while still having fun. In the coming months the team will hold a “Trashion” show where students can create outfits out of trash or other items that were about to be thrown away and a “Weigh the Waste” event to educate the campus community about the effects of food waste.

    This semester the Green Campus Team will also relaunch the Green Workplace Assessment Program, including a new sub-program called the Peer To Peer Education Program. Advocates will talk to campus departments and educate them on sustainable practices so they can properly educate their peers. 

    They will also launch a student version of this program called Equal Reps, recruiting students that live on campus to educate others about living green. 

    “It would be great if students, before doing any sort of action, just considered the question and the idea of ‘how can what I’m doing be more sustainable?’” Chung said. “How can I do this in a different way?”

    Chung said this could mean many different things and will look different for everyone.  

    “It could mean completely changing what you’re doing. It could be evaluating if you have the capacity to do more sustainable actions because sometimes there just simply isn’t a possibility with other things you have going on,” Chung said.

    The Waste Reduction and Resource Awareness Program has brought back the paper towel composting project this semester. WRRAP also gives out composting buckets for on-campus residents, as well as finished compost to anyone who wants it. 

    “Students should keep an eye out for signs in the restrooms marking which bin is for paper towels and which is for other waste,” WRRAP said in an email to the Lumberjack. “This is a great help when we go to do our final sorting before placing the paper towels in the on-campus industrial composter.”

    Chung explained that when planning events the campus should account for sustainability rather than making adjustments later. Chung suggested that the administration should foster an open dialogue with the Office of Sustainability to ensure that they are making the best decisions for the school long-term.  

    “I think continuing to make sure that [the administration is] keeping sustainability at a forefront rather than an afterthought would be really important for the school,” Chung said. “Especially as we’re making so many big decisions with the new Cal Poly change.” 

    The Green Campus Team has compiled the Zero Waste Event Certification Checklist of different things to keep in mind when planning an event on campus. The checklist includes helpful sustainability tips, like serving food buffet style in reusable containers and ensuring promotional or advertising materials and decorations are reusable, recyclable or compostable. 

    The Green Campus Team is currently looking for another student employee as well as experiential interns and volunteers. To learn more follow the Green Campus Team on Instagram @greencampus_humboldt.

  • How wildfire can cause flooding

    How wildfire can cause flooding

    by August Linton

    After the consuming heat and flame of a wildfire, flooding seems an unlikely problem to have to worry about. But catastrophic floods after a section of land is burned often threaten both human settlements and ecosystems. 

    Post-wildfire flooding can be caused by several processes. According to Cal Poly Humboldt professor of forestry, fire and rangeland management Dr. Jeff Kane, the forest floor normally acts as a sponge, soaking up and slowly releasing rainfall. When a wildfire burns that layer, there’s nothing left behind to stop rainfall from rushing directly downstream.

    Wildfire also can release and vaporize waxy compounds from conifer needles, which then accumulate on the burned ground and form an even more water-resistant layer. 

    “Instead of percolating, [water] may flow overland,” Kane said. “If you don’t have the vegetation to absorb the precipitation, then it’s going to be more impactful.”

    Hydrology and watershed management professor Dr. Andrew Stubblefield says that the impacts of this flooding extend to the whole ecosystem. When the forest floor loses its ability to absorb water, the topsoil can become saturated and eventually sloughs downstream, taking with it the nutrients it stores.

    “Now you have a forest that’s less able to hold water to grow trees and provide nutrients to grow trees,” said Stubblefield. “It’s impoverished, or it’s depleted; and it can take a while to hundreds of years even to rebuild the nutrients.”

    This can impact what plants regrow while the land recovers from the fire and flood. Weedy, often-invasive plants may have an easier time reestablishing themselves in this less-nurturing environment than native species, according to Kane. 

    Soil and nutrients washed into rivers and streams also negatively affect their ecosystems. Sediment and debris carried by flooding associated with the McKinney fire caused fish kill in the Klamath River earlier this August, as clays in the soil interrupted oxygen flow and nutrients nourished a deadly algal bloom. 

    Post-wildfire flooding can also be dangerous to human settlements and to the ecosystem around it because it picks up debris and soil and carries it downstream. Debris flows caused by heavy rain after the Thomas fire in Montecito, California killed 23, injured at least 167, and damaged 408 homes, according to a 2019 research article by J.W. Kean et al. 

    It’s the charge of the National Forest Service’s BAER (Burned Area Emergency Response) teams to analyze the risks for flooding after each fire and implement measures to mitigate damage and environmental impacts. According to the McKinney Post-Fire BAER incident overview, these multidisciplinary teams of scientists decide what, if anything, needs to be done to protect natural resources or human settlements in the area. 

    Examples of possible interventions include seeding the hillside from the air, setting up log breaks along hills or in creek beds, or stabilizing at-risk areas with hydro-mulch (a material similar to paper mâché which also contains seeds,) said Stubblefield. Sometimes the best treatment is to warn people away from at-risk areas with weather alerts when a big storm is coming in.

    But with modern fires often burning millions of acres at once, what scientists can do to mitigate flooding becomes a problem of scale. 

    “The August Complex [fire] last summer was a million acres, what would it cost to try and stabilize that landscape, you know, it’s too big,” said Stubblefield. “It would be the gross domestic product of a small country.”

    Flooding is not an inevitable follow-up to wildfire. It takes both intense fire and intense rain to create the right conditions. If ground cover vegetation like grasses have time to return before the next intense rain, it stabilizes the soil and can even begin to break down the waxy hydrophobic layer.

    However, due to the effects of anthropogenic climate change and poor forest management, the perfect storm happens more often. 

    When this land was stewarded by Native Americans, regular fires were part of that management. In the post-colonial absence of that management, white settlers saw wildfires as something that needed to be suppressed immediately, rather than allowed to run their course as a physiological process of the forest. When the dense, thick, choked forests that this policy produces catch fire, they burn hotter, longer, and over a wider area. The environmental legacy of clear-cut logging and fire-prevention has left the forests in a vulnerable and volatile state.

    “We are moving into an era of active fire management,” said Stubblefield.

    This means more prescribed burns, and an attitude towards fire that acknowledges its essential role in forest health. Post-fire flooding, too, is a physiological component of the ecosystem. According to Stubblefield, if sediments weren’t carried into the river, salmon might not have gravel to spawn on at all.

  • Cal Poly Humboldt’s vertebrate museum opens to the public for the first time

    Cal Poly Humboldt’s vertebrate museum opens to the public for the first time

    by Alina Ferguson

    Cal Poly Humboldt’s campus has a vertebrate museum, dedicated to skulls, skeletons, skins, and tissue from various mammals and vertebrates, such as rats, mice, and sea mammals native to Humboldt county. This student-run museum has about 15,000 specimens, 9,000 of which are available for viewing. 

    The museum is now allowing all students a peek into their collections, which include rodents, otters, seals, and taxidermied elk. Students are also able to view the anatomical study processes such as dissection and labeling.

    Previously, the collection was only accessible to students within the wildlife major. The students would look through the collection and study the specimens, testing their ability to identify them. Now, for the first time since the museum was established in 1969, the museum is open to all students during their open hours on Monday from 11am to 4pm, and Tuesdays through Fridays 12pm to 5pm.

    Shea Daly, a senior who works in the lab and does most of the preparations, extended an open invitation to all students.

    “On the last Friday of the month, we are going to have open labs and live dissections, so come in and ask questions,” Daly said. “We are also trying to start up scientific drawing classes.” 

    Daly added that students from all majors are welcome to come in and watch the process of dissecting and skinning the animals.  

    “The students are very hands-on. They can do preps, they can do skeletonizing, which is the process of dipping the bones into an ammonia bath to make them whiter,” Daly said.

    In the past, the staff would forage and scrounge for their own specimens. According to Collections Intern Ezra Alberts, now they get most of their specimens from donations, people finding roadkill on the highway, and the marine mammal training program. 

    Silvia Pavan, the faculty advisor and grant funding organizer to the museum, explained that they typically only need to work with the skull of the animal, as it provides the most information. The rest of the bones are disposed of in a biohazard bin if there is no room for them in the lab or the museum. 

    Opening a freezer full of numbered vials of tissue samples, Pavan explained the process of tagging each animal and the importance of it. Once an animal has been skinned and deboned, each corresponding part must be labeled and numbered. This tracking lets them trace where the tissue samples came from, the food samples of the animal, and the genealogy of the species.

    The museum has a second room, the bug room, where they process the bones that have any remaining flesh or tissue still attached. The bones are placed into a container, where dermestid beetles eat away at everything but bone. Depending on the animal, the carcass may be there for a few days or a few weeks. 

    A large portion of the work the museum does is tissue sampling, genetics, and CT scanning. This work helps the scientists determine what it ate, where it came from, and ultimately, what killed it.
