Sea Ice Update

The cap of floating sea ice that covers the Arctic Ocean melted in the summer of 2012 to its smallest size in nearly 35 years of satellite observations. But as frigid fall and winter temperatures swept over the region, the Arctic seas refroze and the dynamic mass of ice grew again toward its annual peak, reaching it on February 28, 2013. These two seasonal milestones—the Arctic sea ice minimum and maximum—are closely watched by NASA scientists and used as benchmarks of climate change. While the drastic shrinking of the minimum has gained attention in recent years, the maximum has also declined in size but at a slower rate. Still, nine of the 10 smallest maximums in the satellite era occurred in the past decade, with the 2013 maximum ranking as the fifth smallest since 1978. Watch the visualization to see satellite observations of Arctic sea ice from March 2012 through February 2013.
