Sea Ice Patterns

On July 20, the U.S. Coast Guard Cutter Healy steamed south in the Arctic Ocean toward the edge of the sea ice.


The ICESCAPE mission, or "Impacts of Climate on Ecosystems and Chemistry of the Arctic Pacific Environment," is NASA's two-year shipborne investigation to study how changing conditions in the Arctic affect the ocean's chemistry and ecosystems. The bulk of the research takes place in the Beaufort and Chukchi seas in summer 2010 and 2011.
