Arctic Sea Ice Minimum for 2010: Third-lowest extent

The 2010 sea ice melt season ended in the Arctic, with the ice extent reaching its low for the year at 4.60 million km² (1.78 million sq. miles) on September 19, the National Snow and Ice Data Center (NSIDC) reported, adding that 2010 Arctic sea ice extent was the third-lowest on the satellite record. (The record low of 4.13 million km² was set in 2007). Both the Northwest Passage and the Northern Sea Route were open for a period during September.


Arctic sea ice extent for September 2010 was 4.90 million square kilometers (1.89 million square miles), the third-lowest in the satellite record. The magenta line shows the median ice extent for September from 1979 to 2000. Sea Ice Index data. Click images to enlarge.

The updated time series plot puts this summer’s sea ice extent in context with other years. The solid light blue line indicates 2010; dark blue shows 2009, purple shows 2008; dashed green shows 2007; light green shows 2005; and solid gray indicates average extent from 1979 to 2000. —Credit: National Snow and Ice Data Center
