OS13F:
High-Resolution Ocean Modeling for Ocean–Ice Interaction Around the Greenland and Antarctic Ice Sheets Posters


Submit an Abstract to this Session


Session ID#: 49860

Session Description:
Understanding the impact of hydrographic variability on the melting of the Greenland and Antarctic Ice Sheets requires high-resolution numerical ocean modelling that spans from basin- (1000s km) to regional-scale (1-100s km) and smaller, emphasizing the importance of exchanges between these scales.  Although progress has been made by studying ocean-ice sheet interaction using numerical models with idealized and realistic geometries and forcings, many unanswered questions remain.  It is hoped that the work shared in this session will help shed light on outstanding questions relating to the importance of decadal to seasonal hydrographic variability in the (1) North Atlantic subpolar gyre, Greenland-Iceland-Norwegian Seas, and Baffin Bay on anomalous melting of the Greenland Ice Sheet and in the (2) Southern Ocean on anomalous melting of the West Antarctic Ice Sheet and potential 'hot spots' around East Antarctica.
