Arctic Sea Ice Extent Ties for Second Lowest Summer Minimum Extent

September 27, 2016
By Jessica Rohde

Arctic sea ice extent for September 10, 2016 was 4.14 million square kilometers (1.60 million square miles). The orange line shows the 1981 to 2010 median extent for that day. The black cross indicates the geographic North Pole. Image derivation is from the NSIDC Sea Ice Index data product, which relies on NASA-developed methods using passive microwave data from the Defense Meteorological Satellite Program (DMSP) F-18 Special Sensor Microwave Imager/Sounder (SSMIS).


The National Snow and Ice Data Center (NSIDC) noted this year's minimum Arctic sea ice extent on September 10, at 4.14 million square kilometers. This tied with 2007 for the second lowest minimum extent in the satellite record  (1979-present). September’s low extent followed a summer characterized by conditions generally unfavorable for sea ice loss. Read more at

NSIDC will post an analysis of the 2016 melt season, including a discussion of the Antarctic sea ice growth season, during the first week of October at
