See sea ice cover in the Arctic will have reached its maximum extent, for the year and according to the scientists with the national snow and ice data center, this scope ties 2006 for the lowest on record.
Watch a time lapse movie of sea ice, as it waxes and wanes in the course of a year is a bit like just a lung inhalation and exhalation. In the months of autumn and winter, it expanded steadily until it reached its greatest extent - usually somewhere in the March - and then it moves to lowest area where rule reached in September.
Arctic ice is younger, thinner and disappear
As Arctic temperatures warm, especially in the summer the minimum sea ice extent declined steeply. It is currently declining of 11.5 percent per decade relative to the 1979-2000 average. This decline affected sea ice recovery again in the winter, as the ice, the reforms is now younger and thinner and so less likely to stop. Since the Arctic is an extremely cold environment during the winter months, winter sea ice decline is however less than in the summer: approx. 3 to 4 percent per decade since 1979, when satellite measurements began.
Since the launch of the satellite record is the maximum Arctic sea ice extent 18 February and in March 31, with an average date of March of 6. This year, it seems to have reached its maximum on 7 March. At 14.64 million km2 (5.65 million square miles), the size was 1.2 million square kilometres (471,000 square miles) below the 1979 to 2000 of 15.86 million km2 (6.12 million square miles) average, and maximum equal to 2006 for the lowest amount in the satellite record.
