The Latest on Snow and Ice

7 January 2020

The year 2019 saw an early melt onset and high sea surface temperatures during summer in the Beaufort and Chukchi Seas. The September minimum extent ended up tied with 2007 and 2016 for second... read more

5 December 2019

Arctic sea ice extent for November 2019 ended up at second lowest in the 41-year satellite record. Regionally, extent remains well below average in the Chukchi Sea, Hudson Bay, and Davis Strait.... read more

11 November 2019

Daily melt extent mapping is suspended for the winter. Calibration of yearly melt detection requires analysis of the springtime snow conditions by a separate program. See our ... read more

8 November 2019

Low winter snow cover, springtime heat waves, and a sunny summer led to a large runoff of meltwater from the Greenland ice sheet in 2019, primarily from its western side.
