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 4, 2009 through January 30, 2011. Over the water, Arctic sea ice changes from day to day showing a running 3-day average 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 miniimum 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.

This composite animation shows the sea ice over the star background.

This shows the sea ice with transparency without the background star field.
