            "description": "Using five years of data from NASA's Ice, Cloud and land Elevation Satellite (ICESat), a team of NASA and university scientists made the first basin-wide estimate of the thickness and volume of the Arctic Ocean ice cover between 2003 and 2008. The scientists found that younger, thinner ice has replaced older, thicker ice as the dominant type over the past five years. Until recently, the majority of Arctic ice survived at least one summer and often several. That balance has now flipped. Seasonal ice, or ice that melts and re-freezes every year, now comprises about 70 percent of the Arctic sea ice in wintertime, up from 40 to 50 percent in the 1980s and 1990s. Thicker ice - surviving two or more years - now comprises just 10 percent of ice cover, down from 30 to 40 percent in years past.Sea ice thickness has been hard to measure directly so scientists have typically used estimates of ice age to approximate thickness. With ICESat, NASA scientists were for the first time able to monitor the ice thickness and volume changes over the entire Arctic Ocean. The Arctic ice cap grows each winter as the sun sets for several months and intense cold sets in. The total volume of winter Arctic ice is equal to the volume of fresh water in Lake Superior and Lake Michigan combined. Some of that ice is naturally pushed out of the Arctic by winds, while much of it melts in place. But not all of the ice in the Arctic melts each summer, and the thicker, older ice that survives one or more summers is more likely to persist through the next summer. This older, thicker ice is declining thinner ice that is more vulnerable to summer melt. Seasonal sea ice usually reaches about 2 meters (6 feet) in thickness, while ice that has lasted through more than one summer averages 3 meters (9 feet), though it can grow much thicker in some locations near the coast. From 2003 to 2008, multi-year ice has thinned by an average of 60 centimeters (2 feet). The total ice volume in winter has decreased by 6,300 cubic kilometers, or 40 percent. The maximum extent of multi-year ice is now one-third of what it was in the 1990s. || ",

            "description": "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.  This animation shows a 3-year moving average of the perennial ice cover, or minimum sea ice concentration,  for from 1979-1981 through 2004-2006. 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. This decrease is evident in the animation shown here.This is an update of animation ID #3267. || ",
