RUSALCA Arctic Food Web Structure and Epibenthic Communities in a Climate Change Context

Project Description

The goal of the RUSALCA program is to gather climate quality long-term physical, chemical and biological observations of the northern Bering and Chukchi Seas ecosystems to document the status quo and potential change in this region. We analyze benthic food web structure and epibenthic community as meaningful key variables for long-term climate observations, because they reflect water mass properties and the extent of pelagic-benthic coupling on the Arctic shelf, as well as habitat characteristics (community measure).
