    "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 visualization shows Artic sea ice from July 1, 2008 through Septemeber 14, 2008 based on the DMSP/SSMI instrument. The minimum Arctic sea ice extent occurred the week of September 12, 2008, when the extent was 4.52 million sq km (1.74 million sq miles). || ",

The annual cycle starts with the maximum extent reached on March 15, 2012. Every summer the Arctic ice cap melts down to its minimum extent before colder weather builds the ice cover back up. This new ice generated on an annual basis is called \"first-year\" ice and is thinner than the older sea ice. The perennial ice is the portion of the ice cap that spans multiple years and represents its thickest component. On September 13, 2012, the sea ice minimum covered 3.439 million square kilometers, that is down by more than 3.571 million square kilometers from the high of 7.011 million square kilometers measured in 1980. The annual maximum extent for 2013 reached on February 28 reached an extent of 15.09 million square kilometers. || ",
