A twenty-first century structural change in Antarctica’s sea ice system
Communications Earth & EnvironmentFrom 1979 to 2016, total Antarctic sea ice extent experienced a positive trend with record winter maxima in 2012 and 2014. Record summer minima followed within the period 2017-2024, raising the possibility that the Antarctic sea ice system might be ...

The key role of the Southern Annular Mode during the sea-ice maximum for Antarctic sea ice and its recent loss [PDF]
Communications Earth & EnvironmentAntarctic sea ice exhibits considerable interannual variability and has experienced unprecedented decline over the past decade. Here we provide observational insights into the role of the Southern Annular Mode in driving such variations in Antarctic sea ...

Compounding tropical and stratospheric forcing of the record low Antarctic sea-ice in 2016. [PDF]
Nat Commun, 2019 After exhibiting an upward trend since 1979, Antarctic sea ice extent (SIE) declined dramatically during austral spring 2016, reaching a record low by December 2016.

Sustained ocean changes contributed to sudden Antarctic sea ice retreat in late 2016. [PDF]
Nat Commun, 2019 After nearly three decades of observed increasing trends of Antarctic sea ice extent, in September-October-November 2016, there was a dramatic decrease. Here we document factors that contributed to that decrease. An atmosphere-only model with a specified

Robust Arctic warming caused by projected Antarctic sea ice loss
Environmental Research Letters, 2020 Over the coming century, both Arctic and Antarctic sea ice cover are projected to substantially decline. While many studies have documented the potential impacts of projected Arctic sea ice loss on the climate of the mid-latitudes and the tropics, little

Microplastic contamination in east Antarctic sea ice.
Marine Pollution Bulletin, 2020 The durability of plastics in the marine environment has led to concerns regarding the pervasiveness of this debris in remote polar habitats. Microplastic (MP) enrichment in East Antarctic sea ice was measured in one ice core sampled from coastal land ...

Arctic and Antarctic Sea Ice Change: Contrasts, Commonalities, and Causes
Annual Review of Marine Science, 2019 Arctic sea ice has declined precipitously in both extent and thickness over the past four decades; by contrast, Antarctic sea ice has shown little overall change, but this masks large regional variability.

Dark metabolism: a molecular insight into how the Antarctic sea-ice diatom Fragilariopsis cylindrus survives long-term darkness. [PDF]
New Phytol, 2019 Summary Light underneath Antarctic sea‐ice is below detectable limits for up to 4 months of the year. The ability of Antarctic sea‐ice diatoms to survive this prolonged darkness relies on their metabolic capability. This study is the first to examine the

Reconstruction of Antarctic sea ice thickness from sparse satellite laser altimetry data via deep learning [PDF]
Scientific DataThe persistent lack of spatially complete Antarctic sea ice thickness (SIT) data at sub-monthly resolution has fundamentally constrained the quantitative understanding of large-scale sea ice mass balance processes.

Positive Trend in the Antarctic Sea Ice Cover and Associated Changes in Surface Temperature. [PDF]
J Clim, 2017 The Antarctic sea ice extent has been slowly increasing contrary to expected trends due to global warming and results from coupled climate models. After a record high extent in 2012 the extent was even higher in 2014 when the magnitude exceeded 20×106 ...
