Advances in Ice Sheet–Ocean Interactions: From Measurements to Climate Impacts Posters


Submit an Abstract to this Session


Session ID#: 46665

Session Description:
The mechanisms driving oceanic melt and regulating freshwater discharge at the margins of the Greenland and Antarctic ice sheets have emerged as critical research areas for understanding and projecting the ice sheets’ contribution to sea level rise and their impact on ocean circulation. However, the complex processes involved, wide range of time/spatial scales, and harsh climate make these uniquely difficult systems to observe and model. We welcome submissions across glaciological and oceanographic disciplines exploiting observational, modelling, or theoretical methods to study ice sheet-ocean interactions. Particularly welcomed are submissions exploiting advances in our satellite remote sensing capabilities (e.g., Sentinel’s, Landsat-8, CryoSat-2 & ICESat). Example topics include: ocean circulation/tranformation at ice sheet margins; ice velocity/elevation changes in response to oceanic forcing; ice melt beneath ice shelves and at tidewater glacier margins; bathymetry and glacier observations; climate sensitivity of physical processes controlling ice-ocean interactions; development of coupled ice-ocean numerical models and melt parameterizations.
