Arctic Daily Sea Ice Concentration from Arctic Minimum 2016 to Arctic Maximum 2017
This animation shows the seasonal change in the extent of the Arctic sea ice between the Arctic minimum, September 10, 2016, and Arctic maximum on March 7, 2017.
Arctic sea ice appears to have reached a record low wintertime maximum extent, according to scientists at NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) in Boulder, Colo. This winter, a combination of warmer-than-average temperatures, winds unfavorable to ice expansion, and a series of storms halted sea ice growth in the Arctic. This year’s maximum extent, reached on March 7 at 5.57 million square miles (14.42 million square kilometers), is only about 40,000 square miles below the previous record low, which occurred in 2016,
The images shown here portray the sea ice as it was observed by the AMSR2 instrument onboard the Japanese Shizuku satellite. The opacity of the sea ice is derived from the AMSR2 sea ice concentration. The blueish white color of the sea ice is derived from the AMSR2 89 GHz brightness temperature. The annual cycle starts with the minimum extent reached on August 31, 2016 and runs through the daily sea ice concentration until the maximum occurs on March 3, 2017. The Arctic’s sea ice maximum extent has dropped by an average of 2.8 percent per decade since 1979, the year satellites started measuring sea ice. The summertime minimum extent losses are nearly five times larger: 13.5 percent per decade. Besides shrinking in extent, the sea ice cap is also thinning and becoming more vulnerable to the action of ocean waters, winds and warmer temperatures.
