Description: Sea ice extent in March 2013 (left) and September 2013 (right), illustrating the respective monthly averages during the winter maximum and summer minimum extents. The magenta lines indicate the median ice extents in March and September, respectively, during the period 1981-2010. Note that the median ice extents are computed over a different time interval than the one (1979-2000) used in previous Arctic Report Cards.
