Animation shows daily Arctic sea ice extents for 2007, 2012, 2019, and 2020. The decadal averages are also included for the 1980s, 1990s, and 2000s. Plot updated through 2/3/2020.

Current year’s sea ice extent (NSIDC, DMSP SSM/I-SSMIS F-18) in addition to climatology (yellow, 1981-2010) and 2 standard deviations from the mean (updated 2/3/2020)

Annual sea ice extent over the Arctic Ocean Basin (Beaufort, Chukchi, East Siberia, Laptev, and Central Arctic Seas) for 2020 (red line) and throughout the satellite era (purple [1979] to white [2019] lines). Plot updated 2/3/2020 using NSIDC Sea Ice Index v3 (DMSP SSM/I-SSMIS F-18).

Current regional Arctic sea ice extents (NSIDC Sea Ice Index v3 : DMSP SSM/I-SSMIS F-18) in addition to 2 standard deviations from the 1981-2010 mean (updated 2/3/2020).

A look at the cumulative change in Arctic sea ice extent for February 2020 (JAXA AMSR2). Updated through 2/3/2020.

Latest daily Arctic sea ice extent (JAXA AMSR2) for 2019. Mean sea ice extents from the 1980s, 1990s, 2000s, and 2010-2018 are also shown by the dashed lines. Yearly minimum extents (2002-2019) are shown by the scatter points with color in reference to the magnitude. Updated 11/1/2019.

Latest daily Arctic sea ice extent (JAXA AMSR2) for 2018. Mean sea ice extents from the 1980s, 1990s, 2000s, and 2010-2018 are also shown by the dashed lines. Yearly maximum extents (2003-2018) are shown by the scatter points with color in reference to the magnitude. Updated 4/18/2019.

Current Arctic sea ice extents (JAXA AMSR2) from 2003-present. Color bars are blue when 2020 has dropped below the prior year. Updated through 2/3/2020.
