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

open access: yesAnnals 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]

open access: yesThe 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.

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

open access: yesClimate 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

Antarctic blue-ice moraines: Analogue for Northern Hemisphere ice sheets? [PDF]

open access: yesQuaternary Science Reviews, 2020
Abstract This paper reviews the distribution, character and age of blue-ice moraines in Antarctica and asks whether there are implications for the study of former Pleistocene ice sheets in the Northern Hemisphere. Blue-ice forms where acceleration of downslope katabatic winds removes snow and causes ice to ablate.

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

open access: yesContributions 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 ...

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

open access: yesFrontiers 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

Antarctic subglacial hydrology: current knowledge and future challenges [PDF]

open access: yes, 2014
Flood-carved landforms across the deglaciated terrain of Victoria Land, East Antarctica, provide convincing geomorphological evidence for the existence of subglacial drainage networks beneath the Antarctic ice sheet, and motivate research into the ...

Modeling Antarctic ice sheet loss [PDF]

open access: yesScience, 2019
Cryosphere Knowledge of the speed and scale of ice-shelf melting in Antarctica is crucial for estimates of ice sheet loss. How accurate do models need to be to capture these processes and yield useful projections of future ice sheet loss and the resulting sea level rise? To address this question, Goldberg et al.

Antarctic Ice Sheet fertilises the Southern Ocean [PDF]

open access: yesBiogeosciences, 2013
Abstract. Southern Ocean (SO) marine primary productivity (PP) is strongly influenced by the availability of iron in surface waters, which is thought to exert a significant control upon atmospheric CO2 concentrations on glacial/interglacial timescales. The zone bordering the Antarctic Ice Sheet exhibits high PP and seasonal plankton blooms in response ...

ANTARCTIC ICE SHEET SLOPE AND ASPECT BASED ON ICESAT’S REPEAT ORBIT MEASUREMENT [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
Accurate information of ice sheet surface slope is essential for estimating elevation change by satellite altimetry measurement. A study is carried out to recover surface slope of Antarctic ice sheet from Ice, Cloud and land Elevation Satellite (ICESat)
