The 40Mb animation at the left shows the 2007 dramatic loss of multiyear sea ice throughout the year. Multiyear sea ice is older and generally thicker ice - sea ice that has survived at least one melt season (shown in brighter white).

Timeseries of annual and seasonal sea ice extent from 1901-2010.

Compare side-by-side images of Northern Hemisphere sea ice extent for any two dates in the satellite record (1979-present).

View the updated high resolution animation of the 2007 sea ice retreat (01/01/2007 - 09/23/2007). WARNING - This quicktime animation is very large at 200Mb, but it illustrates nicely the temporal evolution of the 2007 sea ice. Animation: 2007 sea ice minimum animation
Additional years: 2002, 2003, 2004, 2005, 2006
