Space-Geodetic Constraints on Glacial Isostatic Adjustment in Fennoscandia [PDF]

Science, 2001
Analysis of Global Positioning System (GPS) data demonstrates that ongoing three-dimensional crustal deformation in Fennoscandia is dominated by glacial isostatic adjustment. Our comparison of these GPS observations with numerical predictions yields an Earth model that satisfies independent geologic constraints and bounds both the average ...

The comparative role of physical system processes in Hudson Strait ice stream cycling: a comprehensive model-based test of Heinrich event hypotheses [PDF]

Climate of the Past
Despite their recognized significance on global climate and extensive research efforts, the mechanism(s) driving Heinrich events remain(s) a subject of debate.

Impact of glacial isostatic adjustment on zones of potential grounding line persistence in the Ross Sea Embayment (Antarctica) since the Last Glacial Maximum [PDF]

The Cryosphere
Ice streams in the Ross Sea Embayment (West Antarctica) retreated up to 1000 km since the Last Glacial Maximum (LGM). One way that bathymetry influenced this retreat was through the presence of local bathymetric highs, or pinning points, which decreased ...

GEORGIA: A Graph Neural Network Based EmulatOR for Glacial Isostatic Adjustment

Geophysical Research Letters, 2023
Glacial isostatic adjustment (GIA) modeling is not only useful for understanding past relative sea‐level change but also for projecting future sea‐level change due to ongoing land deformation.

Sea-level records from the U.S. mid-Atlantic constrain Laurentide Ice Sheet extent during Marine Isotope Stage 3

Nature Communications, 2017
Surprisingly high Pleistocene sea-level markers on the Virginia and North Carolina shoreline are inconsistent with models of Laurentide ice sheet volume during Marine Isotope Stage 3. Here, Picoet al.

The glacial systems model (GSM) Version 25G [PDF]

Geoscientific Model Development
We document the glacial system model (GSM), which is designed for large ensemble ice sheet modelling in glacial cycle contexts. A distinguishing feature is the extent to which it addresses relevant forcing and process uncertainties. The GSM has evolved

Modeling Viscoelastic Solid Earth Deformation Due To Ice Age and Contemporary Glacial Mass Changes in ASPECT

Geochemistry, Geophysics, Geosystems, 2023
The redistribution of past and present ice and ocean loading on Earth's surface causes solid Earth deformation and geoid changes, known as glacial isostatic adjustment.

Evaluating Greenland glacial isostatic adjustment corrections using GRACE, altimetry and surface mass balance data

Environmental Research Letters, 2014
Glacial isostatic adjustment (GIA) represents a source of uncertainty for ice sheet mass balance estimates from the Gravity Recovery and Climate Experiment (GRACE) time-variable gravity measurements.
