Crabby and Stressed Out: Ocean Acidification and the Dungeness Crab

One of the many consequences associated with climate change is ocean acidification. This process occurs when high atmospheric carbon dioxide dissolves into the ocean lowering ocean pH. Concern about ocean acidification has increased recently with the majority of scientific publications about ocean acidification being released in the last 5 years. Despite this uptick in attention, much is still unknown about the effects of ocean acidification on marine organisms.

Our guest this week, Hannah Gossner, a second year Master’s student in the Marine Resource Management Program, is investigating the physiological effects of ocean acidification on Dungeness crab (Metacarcinus magister) with the help of advisor Francis Chan. Most folks in Oregon recognize the Dungeness crab as a critter than ends up on their plate. Dungeness crab harvest is a multimillion dollar industry because of its culinary use, but Dungeness crab also play an important role in the ocean ecosystem. Due to their prevalence and life cycle, they are important both as scavengers and as a food source to other animals.

To study the effect of ocean acidification on Dungeness crab, Hannah simulates a variety of ocean conditions in sealed chamber where she can control oxygen and carbon dioxide levels. Then by measuring the respiration of an individual crab she can better understand the organism’s stress response to a range of oxygen and carbon dioxide ratios. Hannah hopes that her work will provide a template for measuring the tolerance of other animals to changes in ocean chemistry. She is also interested in the interplay between science, management, and policy, and plans to share her results with local managers and decision makers.

Growing up in Connecticut, Hannah spent a lot of time on the water in her dad’s boat, and developed an interest in marine science. Hannah majored in Marine Science at Boston University where she participated in a research project which used stable isotope analysis to monitor changes in food webs involving ctenophores and forage fish. Hannah also did a SEA Semester (not to be confused with a Semester at Sea) where she worked on a boat and studied sustainability in Polynesian island cultures and ecosystems.  Hannah knew early on that she wanted to go to graduate school, and after a brief adventure monitoring coral reefs off the coast of Africa, she secured her current position at Oregon State.

A Space for Me

Minerva presenting at the Radical Imaginations Conference on the panel ” Feminist Radical Imaginations: Marches and Revolutions” with Andrea Haverkamp, Carolina Melchor, Maria Lenzi Miori, Minerva Zayas, and Nasim Basiri

Everyone handles their personal growth differently, and for many finding an identity category can lead to feelings of comfort and an opportunity to find community. However, for folks who identify with more than one category or find identity in LGBTQ+ categories may find difficulty navigating their identity in spaces that have been shaped by the heteronormative majority. Moreover, for people of color, retaining identity in their culture might add another layer of complexity to navigating the path to their goals. Our guest this week, Minerva Zayas a Master’s student in Women, Gender, and Sexuality Studies, is interested in how folks who identify as LatinX and LGBTQ+ navigate the intersection of these identities, especially in university spaces. In particular, Minerva is asking how LatinX, LGBTQ+ individuals engage in a system that has historically catered to white heteronormative college students. Minerva, speaking from personal experience, expects that University life offers little tailored support systems for folks of color who identify as ‘other,’ but that a university campus might offer opportunities to build a support systems that other institutions might lack: the opportunity to participate in a campus cultural/lifestyle community and engage in activism.

For her Master’s, Minerva will conduct interviews with LatinX, LGBTQ+ students and ask questions than run the gamut of identity in sexuality, culture, community, and activism. She hopes to highlight their experiences and examine themes that arise. In addition to her research, Minerva, a poet herself, plans to extend her project in a creative way, ideally through a podcast. After completing her Master’s, Minerva hopes to complete a PhD and has considered becoming a counselor for Spanish-speaking folks. This aim coincides with her mission to bring voice to folks who share identity with her in LatinX culture. Minerva ultimately wants institutions, academia and beyond, to be more inclusive and cognizant of minority identities, but she realizes that change comes from within. By pursuing her aspirations for a PhD and engaging in academia, she hopes that others who share her identity will be drawn to academia so that a system that has been shaped by the majority identity can grow to support all.

Tune in to KBVR Corvallis 88.7 FM this Sunday May, 20 at 7 pm to hear more about Minerva’s research and personal journey to graduate school. Listeners, local and otherwise, can stream the live interview at kbvr.com/listen or find the podcast of Minerva’s episode next week on Apple Podcasts.
