DESCRIPTION: The project will examine the role of warm deep water intrusion onto the West Antarctic continental shelf on the dynamics of the WAIS. This will be done by adding more automatic weather stations; mapping perennial sea ice thickness; and swath mapping of the sea floor. This will be done to model the ocean properties and circulation, atmospheric forcing and sea ice cover and their impacts on the WAIS.
OUTCOMES: Found correlations between ocean mixed layer depth and water temperature maximum. Forcings included: warmer atmosphere and stronger onshore winds; and melt driver upwelling of warm deep water. Faster-moving currents have contributed to melting and reducing traction.
