Jen Walsh

Research Biologist

Jen Walsh is a Research Biologist with the Antarctic Ecosystem Research Division at the Southwest Fisheries Science Center. Her research focuses on the trophic ecology of Antarctic krill. Prior to piloting gliders, she analyzed krill samples obtained from research surveys to study the body condition and trophic position of krill in relation to annual environmental conditions. These days, she analyzes glider data to study the distribution and abundance of krill around the northern Antarctic Peninsula in relation to chlorophyll concentration.  When she’s not virtually chasing gliders around the Southern Ocean, she enjoys kayaking and cooking.
