A 40-y record reveals gradual Antarctic sea ice increases followed by decreases at rates far exceeding the rates seen in the Arctic [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance A newly completed 40-y record of satellite observations is used to quantify changes in Antarctic sea ice coverage since the late 1970s. Sea ice spreads over vast areas and has major impacts on the rest of the climate system, reflecting solar

Drivers of Antarctic sea ice advance. [PDF]
Nat Commun, 2023 Abstract Antarctic 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

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.

Record low Antarctic sea ice coverage indicates a new sea ice state
Communications Earth & Environment, 2023 In February 2023, Antarctic sea ice set a record minimum; there have now been three record-breaking low sea ice summers in seven years. Following the summer minimum, circumpolar Antarctic sea ice coverage remained exceptionally low during the autumn and ...

Antarctic Sea Ice Area in CMIP6 [PDF]
Geophysical Research Letters, 2020 Fully 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 ...

Antarctic Landfast Sea Ice: A Review of Its Physics, Biogeochemistry and Ecology
Reviews of Geophysics, 2023 Antarctic landfast sea ice (fast ice) is stationary sea ice that is attached to the coast, grounded icebergs, ice shelves, or other protrusions on the continental shelf.

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.

Record-low Antarctic sea ice in 2023 increased ocean heat loss and storms. [PDF]
NatureRecent Antarctic sea-ice decline is a substantial source of concern, notably the record low in 2023 (ref. 1). Progress has been made towards establishing the causes of ice loss1, 2, 3, 4–5 but uncertainty remains about its consequences for ocean ...

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.
