How can deep-sea coral skeletons tell stories of surface ocean change? | Rising Sea Voices

February 25, 2022

A discussion with marine biogeochemist Carina Fish.

In this episode, Felicia talks with Carina Fish, a marine biogeochemist and PhD Candidate at UC Davis, and a current NOAA Sea Grant John A. Knauss Fellow. Learn more on the role of deep-sea coral skeletons in our understanding of ocean change past and present. Carina also explains how she found ways to use her knowledge of biogeochemistry to help local communities and advance environmental justice, which she is passionate about. We hope you will enjoy this episode and join us monthly to discover new guests and their work! In the meantime, look below for Carina’s bio and contact information.
Carina Fish is a marine biogeochemist and PhD Candidate at UC Davis in the Department of Earth and Planetary Sciences and a Dr. Nancy Foster Scholar. While she is typically based out at the Coastal and Marine Sciences Institute's Bodega Marine Laboratory, she is a current NOAA Sea Grant John A. Knauss Fellow working on the hill in the US senate for 2022. Carina endeavors to address societal needs through her work, as such the research objectives for her doctoral projects were co-generated with NOAA national marine sanctuary staff. One project illuminates the regional manifestation of marine heatwaves and ocean acidification and their impact on important food web species. In addition, she uses chemistry to unlock deep sea coral stories of past oceanographic changes from both the organic and inorganic parts of their skeletons. As a former Ford Foundation fellow, Carina continues to be passionate about democratizing knowledge through science communication and applying an environmental justice framework to marine and coastal issues. When not at sea or in the lab, she can be gardening or hiking with her husky, Cleo.

Felicia Olmeta-Schult is the 2021 Oregon Sea Grant Resilience Fellow and works to increase the resilience of Oregon communities to the impacts of climate change and coastal natural hazards. She is also ASPN University Project Lead. Felicia has a B.S. in Oceanography from Hawaii Pacific University, a M.A. in Marine Affairs from the University of Rhode Island, and a Ph.D. in Environmental and Natural Resource Sciences from Washington State University. Her dissertation investigated the North Coast of California Marine Life Protection Act Initiative by studying how stakeholders interacted and were involved during the marine protected area (MPA) planning process and how they perceived socio-economic and ecological effects of MPAs. She was a 2018-19 Washington Sea Grant Hershman Fellow at the Washington Department of Ecology Shorelands & Environmental Assistance Program where she participated in the Washington Coastal Resilience Project. She lives in the Pacific Northwest where she enjoys the outdoors hiking and playing in rivers and the ocean. She loves traveling, especially back home to Corsica, a French Mediterranean island, so she can spend time with her family and swim in the warm sea (and not in the frigid waters of the North Pacific Ocean). You can contact her at and follow her on Twitter @FolmetaSchult and on LinkedIn.
