C13G:
Advances in Land Ice-Ocean Interactions: Mechanisms, Impacts, and Synthesis I

Submit an Abstract to this Session



Session ID#: 34166

Session Description:
Ice mass loss from marine-terminating glaciers and terrestrial ice sheets, 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. We welcome submissions from across glaciological and oceanographic disciplines that exploit observational, modelling or theoretical methods to study land ice-ocean interactions. Particularly encouraged are submissions that exploit advances in our satellite remote sensing capabilities (e.g., Sentinel’s, Landsat-8, CryoSat-2 & ICESat). Example topics include: ocean circulation at ice sheet margins; ice velocity and elevation changes in response to oceanic forcing; ice melt beneath ice shelves and at tidewater glacier margins; icebergs and ice mlange; bathymetry, and glacier observations; climate sensitivity of physical processes controlling ice-ocean interactions; development of coupled ice-ocean numerical models.
