2005 Sea Ice over the Arctic derived from AMSR-E
This animation shows the Spring retreat and subsequent Autumn advance of sea ice over the Arctic from 1/1/2005 through 12/31/2005. The false color of the sea ice, derived from the AMSR-E 6.25 km brightness temperature, was designed to highlight the fissures in the sea ice. Moving 3-day minimum brightness temperatures provide a background for smooth ice movement over which the actual daily brightness temperatures were mapped for definition of the ice structures. The sea ice extent was defined by a 3-day moving average of the AMSR-E 12.5 km sea ice concentration, showing as ice all areas having a sea ice concentration greater than 15%.
This image shows sea ice over the Arctic on March 11,2005.
