Variability and Trends in Antarctic Sea Ice

This project will investigate, through modeling and data assimilation, the historical evolution of the Antarctic sea ice–ocean system from 1979 to the present to enhance our understanding of the large-scale changes that have occurred in the sea ice and the upper ocean in response to changes in atmospheric circulation. Project investigators aim to identify key mechanisms, interactions, and linkages between the sea ice, the upper ocean, and the atmosphere that may explain the observed regional changes in Antarctic sea ice and the observed overall increase in Antarctic sea ice extent since 1979.
