Bering Sea Ice Expedition
Research Activities

The Bering Sea Ice Expedition conducted data collection and observations of annual sea ice and the ice-edge ecosystem of the eastern Bering Sea.  In order to examine as many components of the ecosystem as possible, many scientists with many different specialties were involved.  The pages that follow describe some of the many different research activities that took place during our expedition:


Physical Oceanography

Nutrient Chemistry



Fish and Acoustics


Marine Mammals
