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.

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).

The Monterey Event and the Paleocene‐Eocene Thermal Maximum
Geophysical Monograph Series, Page 401-416., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

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 ...

Impacts of Observed Extreme Antarctic Sea Ice Conditions on the Southern Hemisphere Atmosphere
Atmosphere, 2022 The Antarctic sea ice has undergone dramatic changes in recent years, with the highest recorded sea ice extent in 2014 and the lowest in 2017. We investigated the impacts of the observed changes in these two extremes of Antarctic sea ice conditions on ...

Communications Earth & Environment, 2022 The low Antarctic sea ice extent following its dramatic decline in late 2016 has persisted over a multiyear period. However, it remains unclear to what extent this low sea ice extent can be attributed to changing ocean conditions.

Sensitivity of the Antarctic ice sheets to the warming of marine isotope substage 11c [PDF]
The Cryosphere, 2021 Studying the response of the Antarctic ice sheets during periods when climate conditions were similar to the present can provide important insights into current observed changes and help identify natural drivers of ice sheet retreat. In this context, the

Antarctic Sea Ice--a Habitat for Extremophiles [PDF]
Science, 2002 The pack ice of Earth's polar oceans appears to be frozen white desert, devoid of life. However, beneath the snow lies a unique habitat for a group of bacteria and microscopic plants and animals that are encased in an ice matrix at low temperatures and light levels, with the only liquid being pockets of concentrated brines. Survival in these conditions
