Small Multiples of NSIDC North Pole Sea Ice Extent
This is a still image generated from National Snow and Ice Data Center (NSIDC) north pole sea ice extent images. These images are arranged in a grid pattern with the years across the top from 1979 to 2014 and the months running down the image from January to December.
By glancing at the image, the viewer can quickly see the periods during the year when north pole sea ice extent is at minimum and maximum. It is also easy to see how the sea ice has changed over the years. There is no data for December 1987 and January 1988; these dates are left black.
