Phytoplankton and nutrition: Evaluating effects of phytoplankton assemblage composition on food quality for consumers 





Jeanette Gann is an oceanographer with the Ecosystem Monitoring and Assessment (EMA) program at NOAA in Juneau, Alaska. She participates in at-sea surveys throughout Alaska, where she focuses on phytoplankton community changes in the Bering Sea and Gulf of Alaska, including harmful algal blooms (HABs). The focus of her PhD involves investigating nutritional qualities of varying phytoplankton communities through fatty acids. A large piece of her work is looking at how phytoplankton taxa relate to zooplankton and young fish in general, and age-0 walleye pollock in particular. Another piece involves working on a genomics protocol to assess diatom species composition in Alaskan waters with more efficiency than current microscopy techniques are able to accomplish. Additionally, Jeanette is a member of PICES (North Pacific Marine Science Organization) where she serves as chair of the Technical Committee on Data Exchange (TCODE), and serves on the Science Board.
