Reconstructing Antarctic winter sea-ice extent during Marine Isotope Stage 5e [PDF]
Climate of the Past, 2022 Environmental conditions during Marine Isotope Stage (MIS) 5e (130–116 ka) represent an important “process analogue” for understanding the climatic responses to present and future anthropogenic warming. The response of Antarctic sea ice to global warming

Antarctic bedrock topography uncertainty and ice sheet stability [PDF]
, 2015 All Rights Reserved. Antarctic bedrock elevation estimates have uncertainties exceeding 1km in certain regions. Bedrock elevation, particularly where the bedrock is below sea level and bordering the ocean, can have a large impact on ice sheet stability ...

Synoptic mode of Antarctic summer sea ice superimposed on interannual and decadal variability
Advances in Climate Change Research, 2021 In contrast to decreased Arctic sea ice extent, Antarctic sea ice extent shows a somewhat increased trend. There is a large interannual variability of Antarctic sea ice, especially in the Pacific sector of the Southern Ocean.

Observational evidence for a regime shift in summer Antarctic sea ice
Journal of ClimateIn recent years, the Southern Ocean has experienced extremely low sea ice cover in multiple summers. These low events were preceded by a multidecadal positive trend that culminated in record high ice coverage in 2014. This abrupt transition has led some

Brief communication: Increasing shortwave absorption over the Arctic Ocean is not balanced by trends in the Antarctic [PDF]
, 2017 On the basis of a new, consistent, long-term observational satellite dataset we show that, despite the observed increase of sea ice extent in the Antarctic, absorption of solar shortwave radiation in the Southern Ocean poleward of 60° latitude is not ...

2023's Antarctic sea ice extent is the lowest on record
WeatherAntarctic sea ice is a vitally important part of the regional and global climate. In 2023, sea ice extent fell to record lows, reaching unprecedented values for both the summer minimum, winter maximum and intervening freeze‐up period.

Modeled Trends in Antarctic Sea Ice Thickness [PDF]
Journal of Climate, 2014 Abstract Unlike the rapid sea ice losses reported in the Arctic, satellite observations show an overall increase in Antarctic sea ice concentration over recent decades. However, observations of decadal trends in Antarctic ice thickness, and hence ice volume, do not currently exist.

Sea ice trends in climate models only accurate in runs with biased global warming
, 2017 Observations indicate that the Arctic sea ice cover is rapidly retreating while the Antarctic sea ice cover is steadily expanding. State-of-the-art climate models, by contrast, typically simulate a moderate decrease in both the Arctic and Antarctic sea ...

Proteorhodopsin-Bearing Bacteria in Antarctic Sea Ice [PDF]
Applied and Environmental Microbiology, 2010 ABSTRACT Proteorhodopsins (PRs) are widespread bacterial integral membrane proteins that function as light-driven proton pumps. Antarctic sea ice supports a complex community of autotrophic algae, heterotrophic bacteria, viruses, and protists that are an important food source for higher trophic levels in ice-covered regions of ...

Sea-Ice Production in Antarctic Coastal Polynyas Estimated From AMSR2 Data and Its Validation Using AMSR-E and SSM/I-SSMIS Data [PDF]
, 2017 Antarctic coastal polynyas are very high sea-ice production areas. The resultant large amount of brine rejection leads to the formation of dense water.
