Aug 28, 2024 · Shown below are up-to-date satellite observations of the sea ice covers of both the Arctic and the Antarctic, along with comparisons with the historical satellite record of more than 4 decades.
Mar 25, 2024 · In the waters around Antarctica, ice coverage shrank to near-historic lows for the third year in a row. The recurring loss hints at a long-term shift in conditions in the Southern Ocean, likely resulting from global climate change, according to scientists at NASA and the National Snow and Ice Data Center.
In the Arctic, the annual minimum sea ice extent occurs in September and the annual sea ice maximum extent occurs in March. In the Antarctic, the minimum extent occurs in February and the maximum occurs in September.
Sep 13, 2023 · Following the summer minimum, circumpolar Antarctic sea ice coverage remained exceptionally low during the autumn and winter advance, leading to the largest negative areal extent anomalies...
3 days ago · For the second winter in a row, the extent of Antarctic sea ice has been exceptionally below average—and it has just set a new record low for this time of year. Throughout 2024, scientists in ...
Mar 14, 2023 · Antarctic sea ice extent each February from 1979 through 2023. Based on satellite data, extent is the total area where the ice concentration is 15 percent or higher. In the past decade, the February summer minimum has been extremely variable, hitting both near-record highs and record lows.
The monthly Sea Ice Index provides a quick look at Antarctic-wide changes in sea ice. It is a source for consistently processed ice extent and concentration images and data values since 1979. Monthly images show sea ice extent with an outline of the 30-year (1981-2010) median extent for that month (magenta line).
