Reconstructing Antarctic winter sea-ice extent during Marine Isotope Stage 5e [PDF]

open access: yesClimate of the Past, 2022
Environmental conditions during Marine Isotope Stage (MIS) 5e (130–116 ka) represent an important “process analogue” for understanding the climatic responses to present and future anthropogenic warming. The response of Antarctic sea ice to global warming

Explicit representation and parametrised impacts of under ice shelf seas in the z∗ coordinate ocean model NEMO 3.6 [PDF]

open access: yes, 2017
Ice-shelf-ocean interactions are a major source of freshwater on the Antarctic continental shelf and have a strong impact on ocean properties, ocean circulation and sea ice.

Sea ice trends in climate models only accurate in runs with biased global warming

open access: yes, 2017
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 ...

PLISMIP-ANT, an ice-sheet model intercomparison project [PDF]

open access: yes, 2015
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.

Synoptic mode of Antarctic summer sea ice superimposed on interannual and decadal variability

open access: yesAdvances in Climate Change Research, 2021
In contrast to decreased Arctic sea ice extent, Antarctic sea ice extent shows a somewhat increased trend. There is a large interannual variability of Antarctic sea ice, especially in the Pacific sector of the Southern Ocean.

Modeled Trends in Antarctic Sea Ice Thickness [PDF]

open access: yesJournal of Climate, 2014
Abstract Unlike the rapid sea ice losses reported in the Arctic, satellite observations show an overall increase in Antarctic sea ice concentration over recent decades. However, observations of decadal trends in Antarctic ice thickness, and hence ice volume, do not currently exist.

Sudden increase in Antarctic sea ice: Fact or artifact? [PDF]

open access: yes, 2013
Copyright © 2011 American Geophysical UnionThree sea ice data sets commonly used for climate research display a large and abrupt increase in Antarctic sea ice area (SIA) in recent years.

Proteorhodopsin-Bearing Bacteria in Antarctic Sea Ice [PDF]

open access: yesApplied and Environmental Microbiology, 2010
ABSTRACT Proteorhodopsins (PRs) are widespread bacterial integral membrane proteins that function as light-driven proton pumps. Antarctic sea ice supports a complex community of autotrophic algae, heterotrophic bacteria, viruses, and protists that are an important food source for higher trophic levels in ice-covered regions of ...

Recent loss of floating ice and the consequent sea level contribution [PDF]

open access: yes, 2010
We combine new and published satellite observations and the results of a coupled ice-ocean model to provide the first estimate of changes in the quantity of ice floating in the global oceans and the consequent sea level contribution.

An Overview of Antarctic Sea Ice in the Community Earth System Model Version 2, Part I: Analysis of the Seasonal Cycle in the Context of Sea Ice Thermodynamics and Coupled Atmosphere‐Ocean‐Ice Processes

open access: yesJournal of Advances in Modeling Earth Systems, 2021
We assess Antarctic sea ice climatology and variability in version 2 of the Community Earth System Model (CESM2) and compare it to that in the older CESM1 and (where appropriate) real‐world observations.
