The Antarctic Ice Sheet–A Sleeping Giant?

Frontiers for Young Minds, 2022
The coldest, the windiest, the driest: the continent of Antarctica is a place of extremes. Located at the South Pole, Antarctica is covered by a vast ice sheet, millions of years old and in some areas more than 4,000 m thick. If all this ice were to melt, sea levels would rise by roughly 58 m.

Large obliquity-paced Antarctic ice-volume fluctuations suggest melting by atmospheric and ocean warming during late Oligocene

Communications Earth & Environment, 2023
The late Oligocene (~27.8–23 My ago) offers an opportunity to study past climate variability under high-CO2, warmer-than-present and the unipolar (Antarctic) glaciated state.

CHANGE ANALYSIS OF ANTARCTIC ICE SHELVES BASED ON MULTIPLE REMOTE SENSING PRODUCTS [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
The Antarctic ice sheet is well known as the most sensitive and key issue in the global climate change research and is playing a more and more important role for the global sea level change.

THE RESEARCH ON ELEVATION CHANGE OF ANTARCTIC ICE SHEET BASED ON CRYOSAT-2 ALIMETER [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
In this paper, the Cryosat-2 altimeter data distributed by the ESA, and these data are processed to extract the information of the elevation change of the Antarctic ice sheet from 2010 to 2017.

Antarctic Ice Sheet and Radar Altimetry: A Review [PDF]

Remote Sensing, 2009
Altimetry is probably one of the most powerful tools for ice sheet observation. Our vision of the Antarctic ice sheet has been deeply transformed since the launch of the ERS1 satellite in 1991. With the launch of ERS2 and Envisat, the series of altimetric observations now provides 19 years of continuous and homogeneous observations that allow ...

Quantifying the seasonal “breathing” of the Antarctic ice sheet [PDF]

Geophysical Research Letters, 2012
One way to estimate the mass balance of an ice sheet is to convert satellite observed surface elevation changes into mass changes. In order to do so, elevation and mass changes due to firn processes must be taken into account. Here, we use a firn densification model to simulate seasonal variations in depth and mass of the Antarctic firn layer, and ...

How changing the height of the Antarctic ice sheet affects global climate: a mid-Pliocene case study [PDF]

Climate of the Past, 2023
Warming-induced topographic changes of the East Antarctic ice sheet (EAIS) during the Pliocene warm period could have a significant influence on the climate. However, how large changes in the EAIS height could theoretically affect global climate have yet

Investigating the impact of sub-ice shelf melt on Antarctic ice sheet spin-up and projections [PDF]

The Cryosphere
Sub-ice shelf melting is critical for the stability of the Antarctic ice sheet, as it influences ice-shelf buttressing that reduces grounded ice flow. Previous studies have emphasized that uncertainties in the state of sub-ice shelf melting contribute to

The long-term sea-level commitment from Antarctica [PDF]

The Cryosphere
The evolution of the Antarctic Ice Sheet is of vital importance given the coastal and societal implications of ice loss, with a potential to raise sea level by up to 58 m if it melts entirely.

Report on the geomorphological survey in the Soya Coast (JARE-61)

Antarctic Record, 2020
The Antarctic Ice Sheet is a major source of future sea-level rise due to global warming. Reconstruction of the past Antarctic Ice Sheet is essential to understand the mechanism of the Antarctic Ice Sheet response to global and regional climate changes ...
