The Antarctic ice sheet is a continental glacier covering 98% of the Antarctic continent, with an area of 14 million square kilometres (5.4 million square miles) and an average thickness of over 2 kilometres (1.2 mi).
Jun 10, 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.
Aug 23, 2023 · The Antarctic ice sheet's mass has changed over the last decades. Research based on satellite data indicates that between 2002 and 2023, Antarctica shed an average of 150 billion metric tons of ice per year, adding to global sea level rise.
Feb 18, 2020 · Antarctic sea ice peaks in September (the end of Southern Hemisphere winter) and usually retreats to a minimum in February. These image pairs show the average concentration of Antarctic sea ice for the month of September (left) and the following February (right) from September 1990 to February 2021.
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.
Sep 13, 2023 · Record-low sea ice coverage around Antarctica in 2022 and 2023 co-occurred with substantial subsurface ocean warming, which could be indicative of a change in the mechanisms that govern...
The daily Sea Ice Index provides a quick look at Antarctic-wide changes in sea ice. It provides consistently processed daily ice extent and concentration images and data since 1979.
