Chukchi Sea Environmental Studies Program: Benthic Ecology

Project Description

The Chukchi Sea Environmental Studies Program (CSESP) is a multi-disciplinary investigation of the northeastern Chukchi Sea. I manage the benthic ecology to understand spatial and temporal variability of the benthic fauna in this arctic community. My team has investigated meio-, macro- and megafaunal distributions, environmental drivers, food webs, caloric contents, deep-dwelling communities, and much more!
