            "description": "These images show the Arctic sea ice in September 2012 when it reached the smallest extent ever recorded in more than three decades of satellite measurements, according to scientists from NASA and the National Snow and Ice Data Center(NSIDC). Scientists at the NSIDC who calculate the sea ice minimum based on a 5-day trailing average identified September 16 as the lowest day. NASA scientists who calculate area on each individual day identified September 13th, although there is little difference between the two days. The data is from the U.S. Defense Meteorological Satellite Program's Special Sensor Microwave/Imager. The line on the image shows the average minimum extent from the period covering 1979-2010, as measured by satellites. Every summer the Arctic ice cap melts down to what scientists call its \"minimum\" before colder weather builds the ice cover back up. This year, according to NASA scientists, the area covered 3.439 million square kilometers, down by more than 3.571 million square kilometers from the high of 7.011 million square kilometers measured in 1980. The size of this minimum remains in a long-term decline.The sea ice has a slightly different coloration in the last three groups of images below.  In the first four groups, the color of the sea ice has a pale blue tint.  In the final three groups, the sea ice is shown in white. || ",

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 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.A full global version of this animation was initially developed for a Science On a Sphere exhibit.  A smaller subset is shown here focusing on the Arctic region.   The animation is shown on a plane with a geographic (lat/lon) projection, but has been rotated 90 degrees so that the Arctic is in the center of the image.  The animation compares the difference between the perennial sea ice minimum extent on September 21, 2005 and September 14, 2007.

Because the extent of the sea ice is important both for the Arctic marine ecology and for the role it plays in the Earth's climate, understanding the variation of this extent during the year and from year-to-year is vital. Each year, the minimum sea ice extent in the northern hemisphere occurs at the end of summer, in September.
