OM005:
High-Resolution Ocean Modelling for Ocean-Ice Sheet Interaction Studies around the Greenland and Antarctic Ice Sheets


Session ID#: 22287

Session Description:
Investigating how hydrographic variability modulates the melting of the Greenland and Antarctic Ice Sheets with numerical ocean models requires simulations of ocean circulation and exchange processes that span from the basin scale (1000 of km) to the ice shelf cavity or fjord scale (10 km to 100 m). Although valuable progress has recently been made by studying ocean-ice sheet interaction using numerical models with both idealized and realistic geometries and forcings, many unanswered questions remain. This timely session will bring together researchers working in this field with the goal of accelerating progress by facilitating the exchange of scientific findings and technical ideas. Specifically, it is hoped that this session will help shed light on outstanding questions relating to the importance of decadal to seasonal scale hydrographic variability in the (1) North Atlantic Subpolar Gyre, Greenland-Iceland-Norwegian Seas, and the 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. Finally, the research shared in this session will help to advance the design of ocean observation systems that will be required to monitor future ocean-ice sheet interactions.
