Physical processes and feedbacks obscuring the future of the Antarctic Ice Sheet

Geosystems and Geoenvironment, 2022
The Antarctic Ice Sheet holds a vital role in Earth's climate system and its changes have global implications for the climate, sea level, coastal ecosystems and population.

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 ...

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

Modelling the evolution of the Antarctic ice sheet since the last interglacial [PDF]

The Cryosphere, 2014
We present the effects of changing two sliding parameters, a deformational velocity parameter and two bedrock deflection parameters on the evolution of the Antarctic ice sheet over the period from the last interglacial until the present.

West Antarctic Ice Sheet Dynamics in the Amundsen Sea Sector since the Late Miocene—Tying IODP Expedition 379 Results to Seismic Data

Frontiers in Earth Science, 2022
Observations of rapid ongoing grounding line retreat, ice shelf thinning and accelerated ice flow from the West Antarctic Ice Sheet (WAIS) may forebode a possible collapse if global temperatures continue to increase. Understanding and reconstructing West

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

Did the West Antarctic Ice Sheet Create the East Antarctic Ice Sheet? [PDF]

Annals of Glaciology, 1982
The mostly terrestrial East Antarctic ice sheet is ten times larger and probably more stable than the mostly marine West Antarctic ice sheet. It is natural to suppose that the former appeared first, and that perhaps the latter was partially formed from an outflow of East Antarctic ice onto the West Antarctic continental shelf.

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.

Monitoring changes of the Antarctic Ice sheet by GRACE, ICESat and GNSS

Contributions to Geophysics and Geodesy, 2019
In this study, we estimate the ice mass changes, the ice elevation changes and the vertical displacements in Antarctica based on analysis of multi-geodetic datasets that involve the satellite gravimetry (GRACE), the satellite altimetry (ICESat) and the ...

Modeling the Antarctic ice sheet [PDF]

Annals of Glaciology, 1997
A three-dimensional (3-D), high-resolution, non-linearly viscous, non-isothermal ice-sheet model is employed to calculate the “present-day” equilibrium regime of the Antarctic ice sheet and its evolution during the last glacial cycle.
