Sea Ice, Organisms, and Ecosystems Along the Western Antarctic Peninsula

Professor Jeff Bowman

The Palmer Long Term Ecological Research (LTER) Project has been documenting ecological changes along the western Antarctic Peninsula (WAP) since 1993. Located at the dynamic boundary between Antarctic and sub-Antarctic environments, the ecosystems of the WAP are particularly sensitive to variations in sea ice cover, storm patterns and intensity, and oceanographic conditions in the Southern Ocean resulting from changing climate. This lecture will present an overview of the WAP marine ecosystem and will describe ongoing work to understand the complex interplay between sea ice, nutrients, and the microbes at the base of the marine food web.

Instructor: Jeff Bowman is an Assistant Professor in the Integrative Oceanography Division at Scripps Institution of Oceanography. He studies marine microbial processes in a variety of environments, including the Arctic and Antarctic, coastal Ecuador, and here in California. He earned his PhD in Oceanography and Astrobiology at the University of Washington, where he studied the ecology and evolution of bacterial communities inhabiting sea ice.
