Diversity of Antarctic sea ice and under-ice seawater RNA viruses [PDF]
Sea ice is vital to polar ecosystems and serves as a natural laboratory for studying microbial adaptations in extreme environments. Nevertheless, the diversity and ecology of Antarctic marine RNA viruses have not been sufficiently explored.

The key role of the Southern Annular Mode during the sea-ice maximum for Antarctic sea ice and its recent loss [PDF]
Antarctic 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 ...

Virus-Host Interactions and Genetic Diversity of Antarctic Sea Ice Bacteriophages [PDF]
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.

An evaluation of Antarctic sea-ice thickness from the Global Ice-Ocean Modeling and Assimilation System based on in situ and satellite observations [PDF]
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]
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 ...

Recent observations indicate that two cryospheric components, namely the Antarctic sea ice and ice shelf over the Southern Ocean, have been changing over the decades. Here we analyze results from an ocean–sea ice–ice shelf model to examine variability in

ICESat-2 altimeter data could be used to estimate sea ice freeboard and thickness values with a higher measuring accuracy than that achievable with data provided by previous altimeter satellites.

Mid-Holocene Antarctic sea-ice increase driven by marine ice sheet retreat [PDF]
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.
