Altimetry, gravimetry, GPS and viscoelastic modeling data for the joint inversion for glacial isostatic adjustment in Antarctica (ESA STSE Project REGINA) [PDF]

Earth System Science Data, 2018
The poorly known correction for the ongoing deformation of the solid Earth caused by glacial isostatic adjustment (GIA) is a major uncertainty in determining the mass balance of the Antarctic ice sheet from measurements of satellite gravimetry and to ...

Performance analysis of high-resolution ice-sheet simulations

Journal of Glaciology, 2023
Numerical glacier and ice-sheet models compute evolving ice geometry and velocity fields using various stress-balance approximations and boundary conditions. At high spatial resolution, with horizontal mesh/grid resolutions of a few kilometers or smaller,

The last glaciation of Shetland : local ice cap or invasive ice sheet? [PDF]

, 2014
Issue ISBN: 978-82-92-39488-5 This work is supported by the Carnegie Trust for the Universities of ScotlandThe question of whether the Shetland Islands were covered by an ice cap or by an ice sheet during the last glacial cycle (40–10 ka) remains ...

Antarctic ice sheet and oceanographic response to eccentricity forcing during the early Miocene [PDF]

, 2011
Stable isotope records of benthic foraminifera from ODP Site 1264 in the southeastern Atlantic Ocean are presented which resolve the latest Oligocene to early Miocene (~24–19 Ma) climate changes at high temporal resolution (<3 kyr).

Projections of Future Sea Level Contributions from the Greenland and Antarctic Ice Sheets: Challenges Beyond Dynamical Ice Sheet Modeling

Oceanography, 2018
As Earth’s climate warms, rising sea levels are becoming a great concern. Providing substantiated and well-informed guidance on the amount and rate of future sea level rise is important, but remains challenging.

A temperate former West Antarctic ice sheet suggested by an extensive zone of bed channels [PDF]

, 2014
We present radio-echo sounding data and satellite imagery, revealing a series of ancient large sub-parallel subglacial channels preserved in the region between the Möller and Foundation Ice Streams, West Antarctica.

Hysteresis of the Antarctic Ice Sheet With a Coupled Climate‐Ice‐Sheet Model

Geophysical Research Letters
AbstractThe stability of the Antarctic ice sheet under different fixed levels and orbital configurations is explored using a coupled climate‐ice sheet model, starting from either a pre‐industrial ice sheet or an ice‐free, isostatically rebounded geometry.

Airborne radar evidence for tributary flow switching in Institute Ice Stream, West Antarctica: implications for ice sheet configuration and dynamics [PDF]

, 2015
Despite the importance of ice streaming to the evaluation of West Antarctic Ice Sheet (WAIS) stability we know little about mid- to long-term dynamic changes within the Institute Ice Stream (IIS) catchment.

Diverse behaviors of marine ice sheets in response to temporal variability of the atmospheric and basal conditions

Journal of Glaciology
The observed retreat of the grounding line of the present-day ice sheets and the simulated grounding-line retreat of ice sheets under changing climate conditions are often interpreted as indications of marine ice-sheet instability (MISI), driven by a ...

Global ice sheet modeling [PDF]

, 1994
The University of Maine conducted this study for Pacific Northwest Laboratory (PNL) as part of a global climate modeling task for site characterization of the potential nuclear waste respository site at Yucca Mountain, NV. The purpose of the study was to develop a global ice sheet dynamics model that will forecast the three-dimensional configuration of
