Antarctic ice sheet[1] Interannual fluctuations in the Antarctic sea ice extent (SIE) affect the global albedo and heat balance, and they may affect global CO2 levels. We found that the annual trend of sodium ion fluxes in the snowpack in the Dome Fuji region of East Antarctica can serve ...
Sea ice is ice made of frozen sea water, not all ice in the sea is sea ice, icebergs and the debris when they break up is freshwater from glaciers. In the winter months the surface area of Antarctica doubles as the sea freezes, when spring and summer arrive again it begins to melt ...
The spring season of 2022 saw record low sea ice extent in Antarctica that persisted throughout the year. At the beginning of December, the Antarctic sea ice extent was tracking with the all-time low set in 2021. The greatest regional negative anomaly of this low extent was in the central...
Antarctic sea-ice extent has been slowly increasing in the satellite record that began in 19791,2. Since the late 1990s, the increase has accelerated, but the average of all climate models shows a decline3. Meanwhile, the Interdecadal Pacific Oscillation, an internally generated mode of climate ...
The map above showssea ice extentaround Antarctica on September 26, 2012, when ice covered more of the Southern Ocean than at any other time in the satellite record. The map is based on an NSIDC analysis of data from the Special Sensor Microwave/Imagers flown in the DefenseMeteorological Sate...
This Charctic graph of sea ice extent for Antarctica shows the yearly patterns of ice melt and growth since 1979. This graph also highlights the Feb. 21 record low summer minimum and the Sep. 10 record low winter maximum. Credit: NSIDC/Scott Sut...

Despite global warming and Arctic sea-ice loss, on average the Antarctic sea-ice extent has not declined since 1979 when satellite data became available. In contrast, climate model simulations tend to exhibit strong negative sea-ice trends for the same p
