AMSR-E Arctic Sea Ice: September 2009 to March 2010

  • Released Monday, March 29, 2010

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.

In this animation, the Arctic sea ice and seasonal land cover change progress through time, from September 1, 2009 when sea ice in the Arctic was near its minimum extent, through March 30, 2010. The animation plays at a rate of six frames per day or ten days per second. Over the water, Arctic sea ice changes from day to day showing a running 3-day maximum sea ice concentration in the region where the concentration is greater than 15%. The blueish white color of the sea ice is derived from a 3-day running maximum of the AMSR-E 89 GHz brightness temperature. Over the terrain, monthly data from the seasonal Blue Marble Next Generation fades slowly from month to month.
