Polar Sea Ice Levels

The sea ice in the Chukchi Sea to the north of Alaska and far eastern Siberia was at the lowest extent on record for early May, covering an area more typical of early June, according to data from the U.S. National Snow and Ice Data Center.

Sea ice over the Arctic region as a whole on May 14 was at the second-lowest extent since satellite records began in 1979, and slightly above the 2016 record low.

The extent of the sea ice around Antarctica remained at the lowest on record.
