We compare the observations of arctic sea ice thickness estimates from satellites with in situ observations – collected by submarine cruises and moorings under the sea ice, by direct measurement during field camps, by electromagnetic instruments flown over the sea ice, and by buoys drifting with the sea ice – to provide a careful assessment of our capabilities to monitor the thickness of sea ice.

Project investigators aim to improve upon the existing seasonal ensemble forecasting system and use the system to predict sea ice conditions in the arctic and subarctic seas with lead times ranging from two weeks to three seasons.

A new modeling study conducted by Dr. Jinlun Zhang to be published in the Journal of Climate shows that stronger polar winds lead to an increase in Antarctic sea ice, even in a warming climate.

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.
