Session ID#: 12870

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.
