Summer in the Arctic National Wildlife Refuge
September 25, 2003
This colorful image of the Arctic National Wildlife Refuge and the Beaufort Sea was acquired by the Multi-angle Imaging SpectroRadiometer's nadir (vertical-viewing) camera on August 16, 2000, during Terra orbit 3532. The swirling patterns apparent on the Beaufort Sea are small ice floes driven by turbulent water patterns, or eddies, caused by the interactions of water masses of differing salinity and temperature. By this time of year, all of the seasonal ice which surrounds the north coast of Alaska in winter has broken up, although the perennial pack ice remains further north.
