Session OS019 – Physical and Biogeochemical Processes on the Warm Antarctic Continental Shelves

The “warm” continental shelves of West Antarctica, which include the Amundsen and Bellingshausen seas and the West Antarctic Peninsula, are characterized by enhanced on-shelf transport of Circumpolar Deep Water that helps determine on-shelf hydrographic and biogeochemical properties. This warm water also interacts with ice shelves, influencing vertical mixing, overturning rates and ice shelf mass loss, and potentially triggering marine ice sheet instabilities. Warm shelf regions are undergoing rapid, climate-sensitive changes, which have important implications for ocean circulation, biological production and biogeochemical exchange over spatial scales that may extend downstream to the Ross Sea and offshore waters of the Antarctic Circumpolar Current. For this interdisciplinary session, we invite contributions that focus on both observational and modeling studies of ocean circulation, sea ice-ocean and ice shelf-ocean interactions, biogeochemical processes and biological production in Antarctic warm-shelf settings. We are especially interested in studies that explore links among these thematic topics.

Conveners:

Madeline Mamer (Georgia Institute of Technology, Student Convener)
Kiya Riverman (University of Portland)
Peter Sedwick (Old Dominion University)
Robert Sherrell (Rutgers University)
Andrew Thompson (Caltech)
