      This NSF-funded project aims to:
           (1) Examine the historical evolution of the arctic ice-ocean system to understand the large-scale changes that have occurred in sea ice and the upper Arctic Ocean.
           (2) Project a diminished arctic sea-ice cover under multiple warming scenarios to understand key linkages among atmospheric forcing, sea-ice processes, and oceanic processes in an ice-diminished Arctic Ocean and the adjacent seas.
