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 ...

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.

Anomalous peak in Antarctic sea‐ice area, Winter 1998, coincident with ENSO [PDF]
, 2001 The results of an updated satellite analysis of hemispheric and regional Antarctic sea-ice cover are presented based on October 1987-September I999 Special Sensor Microwave/Imager (SSM/I) data.

Sea Ice–Ocean Feedbacks in the Antarctic Shelf Seas [PDF]
Journal of Physical Oceanography, 2019 AbstractObserved changes in Antarctic sea ice are poorly understood, in part due to the complexity of its interactions with the atmosphere and ocean. A highly simplified, coupled sea ice–ocean mixed layer model has been developed to investigate the importance of sea ice–ocean feedbacks on the evolution of sea ice and the ocean mixed layer in two ...

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

Estimating summer sea ice extent in the Weddell Sea during the early 19th century [PDF]
Climate of the Past, 2023 Over the past 3 decades, discordant trends in sea ice extent have been observed between the Arctic and Antarctic regions. Arctic sea ice extent has been characterised by a rapid decline, whereas Antarctic sea ice extent, while highly variable ...

Antarctic Sea Ice Area in CMIP6 [PDF]
Geophysical Research Letters, 2020 AbstractFully coupled climate models have long shown a wide range of Antarctic sea ice states and evolution over the satellite era. Here, we present a high‐level evaluation of Antarctic sea ice in 40 models from the most recent phase of the Coupled Model Intercomparison Project (CMIP6). Many models capture key characteristics of the mean seasonal cycle

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.
