Zoe is a junior at Bowdoin, a liberal arts college in Maine.  She recently graduated from Sehome in 2017 and is now majoring in Biochemistry and Earth and Oceanographic Science. Her primary interests are molecular-scale biological and chemical interactions behind the planet's changing ocean systems, specifically the single-celled organisms that facilitate nutrient and chemical transformations in the ocean. 

Zoe will be discussing the specific role of the ocean in the absorption of carbon dioxide emissions, as well as how density and biological processes play a huge role in circulation and processing of carbon!

Zoe's topic:

climate change below the surface

Zoe answers your questions!

What the sehome community has to say about Zoe's seminar:

"I thought that this seminar was super interesting, and I learned some pretty cool new things. In ocean science we had learned about the convection cycle that drives the entire world’s currents, so that was just review, but the biological pump was new information. I never really thought about how the ocean stores the carbon that phytoplankton absorbs, and I definitely didn’t know about the phytoplankton eating bacteria. I also didn’t know that there were actually potential positives to climate change—that increased ocean temperatures could lead to more phytoplankton, and therefore more carbon dioxide removal from the atmosphere."

"I personally have not put that much thought into the idea of ocean science but I found Zoe’s talk really interesting. Obviously climate change is a major dilemma, but we rarely hear about the positive aspects, like the increase in phytoplankton. I also like that she touched on how interconnected everything is, and that environmental problems need to be battled with all different kinds of perspectives and scientific backgrounds."

"I really enjoyed Zoe’s presentation because it was a lot of simple concepts, but she explained how they make a really big impact and are very important in terms of climate change and what is happening with our oceans. I also really loved how she talked about how she likes ocean science because it is a blend of chemistry, physics, and biology. That really resonated with me because I also really enjoy all these subjects and it would be hard to choose just one! I also thought it was cool how most of the concepts were things that we have already learned, but she connected them in a new way to convey the bigger picture and how they all relate to each other."

What the Sehome Community has to say about Sasha's Seminar

"I really enjoyed all of the MAYhem seminars, especially because they all focused on different aspects of climate change such as ocean acidification, the loss of sea ice, waste, and a more political and regulatory point of view. I think my favorite seminar was Sasha’s seminar on waste and the carbon emissions that are produced from the agricultural and fashion sectors because that is part of the issue is really easy to relate to your own life and habits."

Carter's Seminar

carter johnson


Carter Johnson is a recent graduate of the University of Washington where he majored in Aquatic and Fishery Sciences. As a student at Sehome in 2010-14, he was a member of the cross country team, played in band, and participated in Science Olympiad. Now, Carter spends much of his free time diving and taking photos around Puget Sound. He currently lives in Seattle where he works as a lab technician in an environmental chemistry lab. Carter will be presenting on the chemistry of ocean acidification and the effects that it has on a variety of marine organisms.

What the sehome community has to say about Carter's Seminar: 

"I liked that this talk was more in-depth. I have frequently looked at ocean acidification as a one sided system, when in reality it is connected to many different events such as algae or kelp bloom. There are side effects that could be positive or negative, and all we can do is maintain our hope."

"I found the talk overall very interesting. I liked that I could see the things that I’ve learned in a textbook and in theory and see their effects in real life situations. For example learning about pH and chemical equations seemed way more important and interesting after seeing how they are effecting and interacting with an ecosystem on a day to day basis. I also found the adaptability of sea creature very interesting as well. Nature never gives up and never ceases to amaze."

"That is why it is important that everyone does what one can to fight this crisis, because no one is too insignificant to make a positive change in the world."

"I thought that Carter’s talk was interesting. I liked how he explained all the inter-connectedness that went along with what he was talking about. I think it was good that he talked about the logarithmic structure of the pH scale, because I think that many people don’t know or think about it like that, and therefore, they aren’t really thinking about it correctly. Carter explained that well, and it made me see some of his charts about Δ pH differently I especially liked how he included the graph recording CO2 levels in their concordance to ice ages over past millennia, because I know many people see climate change as just another instance of the phenomena present in those charts, instead of realizing how large the current climate change is proportionally. I would ask Carter a question similar to what Dr. Smith was asked: “How would you explain the importance of your work/the subject to someone who doesn’t think climate change is real?” I would also ask about how the “change in community” Carter is seeing on his dives. Since he said that the community changes and fluctuates on a month to month basis, how could we use that has evidence for large trends that may be related to climate change. Finally, I would ask about how salmon would be affected, because they live a portion of their lives in fresh, and then salt water. My favorite part was definitely when he did the demo in the middle of his video, very unique and cool!"

Mr. Greve is a strategic policy advisor for King County’s Department of Natural Resources working on a range of programs and policies for land conservation and acquisition. Prior to this current role he developed King County’s Transfer of Development Rights and Aquatic Mitigation Programs from 2007 - 2015 and brings a valuable national perspective on market-based solutions for land conservation, restoration, and environmental protection to address climate change.

Darren expanded the market in development right trading to achieve over $24 million in trades and 55,000 acres of permanent forest and farm land protection in the Pacific Northwest. Darren also oversaw work on over $9 million worth of mitigation credit sales to the private and public sectors.

Prior to his work at King County, Darren worked for Solimar Research Group in an advisory role to local governments across the country looking to adopt growth management, land protection, and market-based conservation policies.

Darren holds an M.A. in Environmental Economics & Policy (2005) from the Bren School at UC Santa Barbara and a B.S. in Chemistry from the Colorado College (1997). He is a 2007 Kinship Conservation Fellow where he focused on market-based solutions to the Puget Sound Region’s environmental challenges.

What the sehome community has to say about Darren's Seminar: 

"I found that listening to Daren Greve was somewhat of a reality check and also made me more hopeful. By listening to him talk about climate change from a governmental perspective I was able to start thinking about our actions in a different way. When I hear people talking about actions to take when it comes to climate change I often focus on the things that I can do personally in my day to day life and it was interesting to shift my thinking towards the larger actions that are being taken by our governments. One other thing that I found interesting was the goals that king county has set in terms of transitioning to clean energy. It made me hopeful because they seemed to be more optimistic than I would have expected."

"Listening to Greve’s talk I learned a lot about the relations between government on the city level and how it expands upwards to the county level. It was interesting to develop a deeper understanding of what aspects of climate legislation the county has power over, how they convey it to city governments, and how it is implemented over a larger region. I liked learning about how policies are developed and implemented."

"The Seminar given by Darren Greve was in some ways refreshing because it was about something positive in connection to the efforts made to combat climate change. It was nice to learn about how at the political level how a highly populated county is trying to try to limit their environmental impacts. I was very surprised by their goals for emission reduction. For example, by 2030 they want to reduce their emissions by 50%. Which sounds crazy and I never really thought would be possible in a very highly populated place. It gave me some hope for the longevity of the planet. Probably one of the most surprising this for me out of the whole seminar was how King County was able to have 2 of the most energy intensive lines of business (waste water treatment/ solid waste disposal) agree to work towards being carbon neutral by 2025. It one thing for having one small business make changes in the type of light bulbs to use but it is a whole other thing to have energy intensive lines of businesses to make a change. I found it interesting how those types of businesses are working towards being carbon neutral. They are capturing the methane/ biogas released and then burning it to create electricity to use to operate."
