Seasonal prediction and predictability of regional Antarctic sea ice

Journal of Climate, 2021
Compared to the Arctic, seasonal predictions of Antarctic sea ice have received relatively little attention. In this work, we utilize three coupled dynamical prediction systems developed at the Geophysical Fluid Dynamics Laboratory to assess the seasonal

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 ...

Causes of the Abrupt and Sustained 2016–2023 Antarctic Sea‐Ice Decline: A Sea Ice–Ocean Model Perspective

Geophysical Research Letters
Antarctic sea ice, which undergoes large seasonal changes and plays a crucial role in the global climate system, showed a gradual increasing trend in its extent from the late 1970s to 2015 but experienced a sharp decline in 2016, followed by record lows ...

Snow on Antarctic sea ice

Reviews of Geophysics, 2001
Snow on Antarctic sea ice plays a complex and highly variable role in air‐sea‐ice interaction processes and the Earth's climate system. Using data collected mostly during the past 10 years, this paper reviews the following topics: snow thickness and snow type and their geographical and seasonal variations; snow grain size, density, and salinity ...

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.

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

Climate 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

Observations of exponential wave attenuation in Antarctic sea ice during the PIPERS campaign

Annals of Glaciology, 2020
Quantifying the rate of wave attenuation in sea ice is key to understanding trends in the Antarctic marginal ice zone extent. However, a paucity of observations of waves in sea ice limits progress on this front.

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.

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

Advances 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.
