Drivers of Antarctic sea ice advance. [PDF]
Nat Commun, 2023 AbstractAntarctic sea ice is mostly seasonal. While changes in sea ice seasonality have been observed in recent decades, the lack of process understanding remains a key challenge to interpret these changes. To address this knowledge gap, we investigate the processes driving the ice season onset, known as sea ice advance, using remote sensing and in ...

Delayed Antarctic sea-ice decline in high-resolution climate change simulations. [PDF]
Nat Commun, 2022 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.

Observed Antarctic sea ice expansion reproduced in a climate model after correcting biases in sea ice drift velocity. [PDF]
Nat Commun, 2021 The Antarctic sea ice area expanded significantly during 1979-2015. This is at odds with state-of-the-art climate models, which typically simulate a receding Antarctic sea ice cover in response to increasing greenhouse forcing.

Sea ice trends in climate models only accurate in runs with biased global warming [PDF]
, 2016 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 ice covers.

Virus-Host Interactions and Genetic Diversity of Antarctic Sea Ice Bacteriophages [PDF]
mBio, 2022 Although we know the generally appreciated significant roles of microbes in sea ice and polar waters, detailed studies of virus-host systems from such environments have been so far limited by only a few available isolates.

Improved simulation of Antarctic sea ice due to the radiative effects of falling snow [PDF]
Environmental Research Letters, 2017 Southern Ocean sea-ice cover exerts critical control on local albedo and Antarctic precipitation, but simulated Antarctic sea-ice concentration commonly disagrees with observations.

The association of Antarctic krill Euphausia superba with the under-ice habitat. [PDF]
PLoS ONE, 2012 The association of Antarctic krill Euphausia superba with the under-ice habitat was investigated in the Lazarev Sea (Southern Ocean) during austral summer, autumn and winter.

Antarctic Sea Ice—A Polar Opposite? [PDF]
Oceanography, 2012 As the world's ice diminishes in the face of climate change—from the dramatic decline in Arctic sea ice, to thinning at the margins of both the Greenland and Antarctic ice sheets, to retreating mountain glaciers the world over—Antarctic sea ice presents ...

Thickness distribution of Antarctic sea ice [PDF]
Journal of Geophysical Research: Oceans, 2008 Ship‐based observations are used to describe regional and seasonal changes in the thickness distribution and characteristics of sea ice and snow cover thickness around Antarctica. The data set comprises 23,373 observations collected over more than 2 decades of activity and has been compiled as part of the Scientific Committee on Antarctic Research ...

An evaluation of Antarctic sea-ice thickness from the Global Ice-Ocean Modeling and Assimilation System based on in situ and satellite observations [PDF]
The Cryosphere, 2022 Antarctic sea ice is an important component of the Earth system. However, its role in the Earth system is still unclear due to limited Antarctic sea-ice thickness (SIT) data. A reliable sea-ice reanalysis can be useful to study Antarctic SIT and its role
