2018 Arctic Sea Ice Ties for Sixth Lowest Minimum Extent on NASA Record
Arctic sea ice reached its annual minimum extent Sept. 19, and then again on Sept. 23, 2018.
NASA works with the National Snow and Ice Data Center to track sea ice in the Arctic as it grows to a maximum extent through the winter and shrinks back to to its minimum extent in September. This year’s minimum sea ice extent reached 1.77 million square miles -- tied as the sixth lowest sea ice minimum since consistent satellite records began.
This year is tied with 2008 and 2010 for the sixth lowest sea ice extent on the satellite record.
