Title: 
Sea Ice Minimum Concentration 3-year moving averages for 1979-1981 to 2004-2006
Instrument: 
DMSP/SSMI
Description: 
Sea ice concentration 3-year average from 2002-2004
Abstract: 
Sea ice is frozen seawater floating on the surface of the ocean. Some sea ice is semi-permanent, persisting from year to year, and some is seasonal, melting and refreezing from season to season. The sea ice cover reaches its minimum extent at the end of each summer and the remaining ice is called the perennial ice cover. This animation shows a 3-year moving average of the perennial ice cover, or minimum sea ice concentration, for from 1979-1981 through 2004-2006. The area of the perennial ice has been steadily decreasing since the satellite record began in 1979, at a rate of about 10% per decade. This decrease is evident in the animation shown here. This is an update of animation ID #3267.
