HE53A:
Response of the Southern Ocean, Sea Ice, and Ice Shelves to the Changing Climate II


Session ID#: 37034

Session Description:
The Southern Ocean plays an important role in the exchange of heat, carbon and nutrients between the atmosphere, surface and deep oceans, and changes in the Antarctic cryosphere. Thus, understanding how the southern ocean responds to external forcing is critical to our understanding of the climate system and climate change. We invite presentations from observational and modeling studies that increase our understanding of the physical, chemical, and biological processes of the Southern Ocean, linkages between these processes, ocean-atmosphere and ocean-ice interactions, and the responses of these processes and interactions to changes in climate.
