The coastal waters of Alaska, as well as mountainous coastal areas elsewhere in the U.S. and Canada, are subject to wind extremes, both in velocity and spatial variability. Coastal areas of the Gulf of Alaska and Bering Sea can experience winds that vary from almost calm to over 25 m/s in only a few kilometers along the shore. This high spatial variability results from winds blowing and accelerating through mountain gaps, downslope winds from glaciers and mountains, as well as wind sheltering by islands and coastal topographic features.
Many relationships with ASF provide unique data products for a great variety of users. One in particular has an especially longstanding and cooperative connection, providing ice breaking vessels with updated navigational information, researchers with products related to polar change, and the public with comprehensive sea-ice atlases and weekly ice data updates.

The finely-detailed imagery of the ocean’s surface from SAR is assuredly the most complex and least understood data set that is provided by a remote sensing instrument.
