Animation shows daily Arctic sea ice extents for 2007, 2012, 2017, and 2018. The decadal averages are also included for the 1980s, 1990s, and 2000s. Plot updated through 1/26/2018.
Latest Arctic sea ice extent (JAXA AMSR2) updated through 1/26/2018.
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 1/26/2018)
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 1/26/2018).
A look at the cumulative change in Arctic sea ice extent for January 2018 (JAXA AMSR2). Updated through 1/26/2018.
Latest daily Arctic sea ice extent (JAXA AMSR2) for 2017. Mean sea ice extents from the 1980s, 1990s, and 2000s are also shown by the dashed lines. Annual absolute minimum extents (2002-2016) are shown by the scatter points with color in reference to the magnitude. Updated 11/3/2017.
Latest daily Arctic sea ice extent (JAXA AMSR2) for 2017. Mean sea ice extents from the 1980s, 1990s, and 2000s are also shown by the dashed lines. Yearly maximum extents (2003-2016) are shown by the scatter points with color in reference to the magnitude. Updated 6/19/2017.
Current Arctic sea ice extents (JAXA AMSR2) from 2003-present. Color bars are blue when 2018 has dropped below the prior year. Updated through 1/26/2018.
