Rapid Spring Melt in the Chukchi Sea

This image shows a large body of open water (shown in blue) in the Chukchi Sea between Alaska & Russia. Bright white areas are sea ice concentrations greater than 50%. Current sea ice extent in the Chukchi Sea is the lowest in the satellite record from 1979 to present for this time of year.

Near Real-Time Sea Ice Concentration Product

The daily, near real-time sea ice concentration product is created from data collected by the Special Sensor Microwave Imager/Sounder (SSMIS) sensor aboard the U.S. Defense Meteorological Satellite Program (DMSP) F-18 satellite & available through NASA’s National Snow and Ice Data Center (NSIDC) DAAC.
