NWFSC Monster Seminar Jam: Gwenn Hennon

Gwenn Hennon (University of Alaska Fairbanks) is presenting a talk, "Towards predicting climate change impacts on phytoplankton communities from the Subtropics to the Arctic."

Abstract

Phytoplankton are responsible for about half of global primary production and form the base of marine food webs- supporting the world’s fisheries. Anthropogenic carbon dioxide has already altered the marine environment through ocean acidification and warming and these trends are predicted to continue at a rapid pace. Forecasting phytoplankton productivity and community composition in a changing climate will be essential for global food security. Our ongoing projects in the Subtropics, the Gulf of Alaska and the Arctic will provide data for these forecasting efforts. Our methods include characterization of marine microbial communities along natural gradients and in situ incubation experiments to disentangle the impact of climate drivers on community composition. We also use experiments with phytoplankton isolates to uncover how climate change will impact phytoplankton physiology and transcriptomics to understand the capacity for phytoplankton to acclimate to these changes.

Bio

Dr. Gwenn Hennon is an Assistant Professor at the University of Alaska Fairbanks in the College of Fisheries and Ocean Sciences. She earned her doctorate from the University of Washington in 2015 and was a postdoctoral researcher at Lamont-Doherty Earth Observatory and a visiting scholar at Scripps Institution of Oceanography before her most recent appointment. Dr. Hennon's lab is focused on questions about how climate change will influence phytoplankton ecology.
