C53E:
Glacier-Ocean Interactions, Mechanisms, and Synthesis II

Submit an Abstract to this Session Please know the abstract submission deadline has passed. There are no exceptions to this deadline and no new abstracts can be submitted.

Session ID#: 17556

Session Description:
Ice mass loss from marine-terminating glaciers, with or without floating ice shelves, is a major contributor to global sea level rise. Our understanding of the physical processes controlling glacier-ocean interactions, however, is limited. This session invites contributions from ice-ocean focused modeling, observation (in situ and remotely sensed), and synthesis projects. Example topics include: ocean circulation at the ice sheet/ocean margins; combined study of in-situ oceanic observations, bathymetry, and glacier observations; ice melt beneath ice shelves or at tidewater glacier margins; the climate sensitivity of physical processes controlling ice-ocean interactions throughout the Arctic, Antarctic, and other glaciated regions; and the development of coupled ice-ocean numerical models.
