Title: 
Comparison of Minimum Sea Ice Between 2005 and 2007 - Split Screen
Instrument: 
DMSP/SSMI
Description: 
This is the background frame of the above animation without any text, state line or California overlay.
Abstract: 
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. The 2007 Arctic summer sea ice has reached the lowest extent of perennial ice cover on record - nearly 25% less than the previous low set in 2005. The area of the perennial ice has been steadily decreasing since the satellite record began in 1979, at a rate of about 10% per decade. But the 2007 minimum, reached on September 14, is far below the previous record made in 2005 and is about 38% lower than the climatological average. Such a dramatic loss has implications for ecology, climate and industry. This animation compares the difference between the perennial sea ice minimum extent on September 21, 2005 and September 14, 2007. With a split screen, the area of the melted region is compared with the size of the state of California.
