AMSR-E Arctic Sea Ice Yearly Maximum from 2003 through 2009
Sea ice is frozen seawater floating on the surface of the ocean, typically averaging a few meters in thickness. 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 maximum extent at the end of each winter, generally in February or March. This series of images of the yearly sea ice maximum extent depicts data from the AMSR-E instrument on the Aqua satellite. The false color in these images of sea ice is derived from the daily AMSR-E 6.25 km 89 GHz brightness temperature while the sea ice extent is derived from the daily AMSR-E 12.5 km sea ice concentration.
