A deglacial model for Antarctica: geological constraints and glaciological modelling as a basis for a new model of Antarctic glacial isostatic adjustment

PL Whitehouse, MJ Bentley, AM Le Brocq - Quaternary Science Reviews, 2012 - Elsevier
We present a new reconstruction of the Antarctic Ice Sheets between 20 ka BP and the
present day. Our reconstruction is derived using a numerical model to generate a physically …

Ocean tide influences on the Antarctic and Greenland ice sheets

L Padman, MR Siegfried, HA Fricker - Reviews of Geophysics, 2018 - Wiley Online Library
Ocean tides are the main source of high‐frequency variability in the vertical and horizontal
motion of ice sheets near their marine margins. Floating ice shelves, which occupy about …

Variable temperature thresholds of melt pond formation on Antarctic ice shelves

JM van Wessem, MR van den Broeke… - Nature Climate …, 2023 - nature.com
It has been argued that the− 5° C annual mean 2 m air temperature isotherm defines a limit
of ice shelf viability on the Antarctic Peninsula as melt ponding increases at higher …

Marine ice sheet collapse potentially under way for the Thwaites Glacier Basin, West Antarctica

I Joughin, BE Smith, B Medley - Science, 2014 - science.org
Resting atop a deep marine basin, the West Antarctic Ice Sheet has long been considered
prone to instability. Using a numerical model, we investigated the sensitivity of Thwaites …

Elevation and elevation change of Greenland and Antarctica derived from CryoSat-2

V Helm, A Humbert, H Miller - The Cryosphere, 2014 - tc.copernicus.org
This study focuses on the present-day surface elevation of the Greenland and Antarctic ice
