Beth E. Caissie, PhD

Beth is a Physical Scientist at the Geology, Minerals, Energy, and Geophysics Science Center. She received a PhD in Geosciences from the University of Massachusetts Amherst in 2012. Since joining the USGS in 2020, she has been working to understand how past climate warming impacted our oceans. She specializes in sea ice extent in the subarctic North Pacific.

Beth Caissie is the lab manager for the Pacific Ocean Patterns, Processes, and Productivity project. In this role, she helps to develop records of ancient sea surface conditions such as sea surface temperature and primary productivity in the North Pacific. Her own research focuses on single-celled algae called diatoms as proxies for sea ice in the Bering and Chukchi seas, Gulf of Alaska, and coastal North Pacific over glacial-interglacial transitions. She is skilled as a micropaleontologist and sedimentologist and also uses organic geochemistry, light microscopy, scanning electron microscopy, and grain size analysis in her work.
