Record low 2022 Antarctic sea ice led to catastrophic breeding failure of emperor penguins
Communications Earth & Environment, 2023 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

Antarctic Landfast Sea Ice: A Review of Its Physics, Biogeochemistry and Ecology
Reviews of Geophysics, 2023 Antarctic landfast sea ice (fast ice) is stationary sea ice that is attached to the coast, grounded icebergs, ice shelves, or other protrusions on the continental shelf.

Environmental Research Letters, 2021 Recent observations indicate that two cryospheric components, namely the Antarctic sea ice and ice shelf over the Southern Ocean, have been changing over the decades. Here we analyze results from an ocean–sea ice–ice shelf model to examine variability in

Mid-Holocene Antarctic sea-ice increase driven by marine ice sheet retreat [PDF]
Climate of the Past, 2021 Over recent decades Antarctic sea-ice extent has increased, alongside widespread ice shelf thinning and freshening of waters along the Antarctic margin. In contrast, Earth system models generally simulate a decrease in sea ice.

Antarctic shelf ocean warming and sea ice melt affected by projected El Niño changes
Nature Climate Change, 2023 How the shelf ocean around Antarctica changes with warming is not well known. Here, the authors show that a projected increase in El Niño–Southern Oscillation variability accelerates warming of the Antarctic shelf ocean but slows warming around the sea ...

The Role of Atmospheric Rivers in Antarctic Sea Ice Variations
Geophysical Research Letters, 2023 Antarctic sea ice variations are affected by moisture and heat from low‐ and mid‐latitudes, more than 90% of which are transported by atmospheric rivers (ARs).

Record Low Antarctic Sea Ice Cover in February 2022
Geophysical Research Letters, 2022 On 25 February 2022 Antarctic sea ice extent dropped to a satellite‐era record low level of 1.92 × 106 km2, 0.92 × 106 km2 below the long‐term mean. The area of sea ice was also at a record low level of 1.24 × 106 km2.

First results of Antarctic sea ice type retrieval from active and passive microwave remote sensing data [PDF]
The Cryosphere, 2023 Polar sea ice is one of the Earth's climate components that has been significantly affected by the recent trend of global warming. While the sea ice area in the Arctic has been decreasing at a rate of about 4 % per decade, the multi-year ice (MYI), also ...

A regime shift in seasonal total Antarctic sea ice extent in the twentieth century
Nature Climate Change, 2022 In stark contrast to the Arctic, there have been statistically significant positive trends in total Antarctic sea ice extent since 1979. However, the short and highly variable nature of observed Antarctic sea ice extent limits the ability to fully ...
