Session ID#: 17518

Session Description:
The marine cryosphere is a complex system that has experienced some of the most extreme environmental changes on Earth, such as declining sea ice extent, warming surface ocean and air temperatures and ecosystem shifts. These influence the global surface energy and moisture budgets, atmospheric and oceanic circulation, and feedbacks. To predict future changes in sea ice it is necessary to understand the complex and coupled interactions between ice, ocean, atmosphere, and land. Improved representation of coupled processes and feedbacks is expected to advance predictive skill of polar weather and climate models, and linkages with lower latitudes. Conveners solicit papers on observational, theoretical and numerical investigations that advance a system level understanding of processes that affect sea ice extent and thickness in the Arctic and Southern Oceans by studying the interaction between ice and at least one other component of the polar system (ocean, ecosystems, atmosphere, land).
