Beth Caissie in front of water

Beth Caissie | Researcher Fellow
The United States Geological Survey (USGS) | Menlo Park, CA

Beth is a paleoceanographer interested in the geologic history of sea ice and how it changes when the Earth warms. She uses single-celled algae–diatoms–to reconstruct sea ice in the subarctic North Pacific Ocean, specifically the Bering Sea. In summer of 2023, Beth will participate in a research cruise that aims to collect sediment cores from above the Bering Land Bridge in order to determine what the ecosystem of the Bering Land Bridge was like during the Last Ice Age and how sea ice changed offshore as climate warmed during the deglaciation.
