Simulating the Antarctic ice sheet in the late-Pliocene warm period: PLISMIP-ANT, an ice-sheet model intercomparison project [PDF]

, 2014
In the context of future climate change, understanding the nature and behaviour of ice sheets during warm intervals in Earth history is of fundamental importance.

DASSO: a data assimilation system for the Southern Ocean that utilizes both sea-ice concentration and thickness observations

Journal of Glaciology, 2021
To improve Antarctic sea-ice simulations and estimations, an ensemble-based Data Assimilation System for the Southern Ocean (DASSO) was developed based on a regional sea ice–ocean coupled model, which assimilates sea-ice thickness (SIT) together with sea-

Compilation of Southern Ocean sea-ice records covering the last glacial-interglacial cycle (12–130 ka) [PDF]

Climate of the Past, 2022
Antarctic sea ice forms a critical part of the Southern Ocean and global climate system. The behaviour of Antarctic sea ice throughout the last glacial-interglacial (G-IG) cycle (12 000–130 000 years) allows us to investigate the interactions between sea

Antarctic Sea Ice Biota [PDF]

American Zoologist, 1991
The sea ice surrounding Antarctica provides an extensive habitat for organisms ranging in size from bacteria to marine birds and mammals. Historically, most of the ecological work on the ice biota has focused in the nearshore land-fast ice. Only in the last decade have there been comparable studies in the deep-water pack ice regions. These studies have

In situ primary production in young Antarctic sea ice [PDF]

, 2002
An in situ incubation technique used successfully to measure the photosynthetic carbon assimilation of internal algal assemblages within thick multiyear Arctic sea ice was developed and improved to measure the photosynthetic carbon assimilation within ...

Combustion of available fossil-fuel resources sufficient to eliminate the Antarctic Ice Sheet [PDF]

, 2015
The Antarctic Ice Sheet stores water equivalent to 58 m in global sea-level rise. We show in simulations using the Parallel Ice Sheet Model that burning the currently attainable fossil fuel resources is sufficient to eliminate the ice sheet.

An Unprecedented Sea Ice Retreat in the Weddell Sea Driving an Overall Decrease of the Antarctic Sea‐Ice Extent Over the 20th Century

Geophysical Research Letters, 2023
Sea‐ice extent is predicted to decrease in a warming climate. However, despite global warming over the past century, total Antarctic sea ice remained relatively stable from 1979 until 2015, before strongly melting.

Ice core reconstruction of sea ice change in the Amundsen-Ross Seas since 1702 A.D. [PDF]

, 2016
Antarctic sea ice has been increasing in recent decades, but with strong regional differences in the expression of sea ice change. Declining sea ice in the Bellingshausen Sea since 1979 (the satellite era) has been linked to the observed warming on the ...

Sources of low-frequency variability in observed Antarctic sea ice [PDF]

The Cryosphere
Antarctic sea ice has exhibited significant variability over the satellite record, including a period of prolonged and gradual expansion, as well as a period of sudden decline.
