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

open access: yesScience, 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 ...

Total isostatic response to the complete unloading of the Greenland and Antarctic Ice Sheets [PDF]

open access: yesScientific Reports, 2022
The land surface beneath the Greenland and Antarctic Ice Sheets is isostatically suppressed by the mass of the overlying ice. Accurate computation of the land elevation in the absence of ice is important when considering, for example, regional ...

Global sea level rise and glacial isostatic adjustment

open access: yesGlobal and Planetary Change, 1999
Abstract The fact that the ongoing global process of glacial isostatic adjustment (GIA) contributes significantly to present-day observed rates of secular sea level change that are recorded on tide gauges is now rather well established. There is a continuing discussion, however, of the magnitude of the globally averaged rate of relative sea level ...

Sensitivity of inverse glacial isostatic adjustment estimates over Antarctica [PDF]

open access: yesThe Cryosphere, 2020
Glacial isostatic adjustment (GIA) is a major source of uncertainty for ice and ocean mass balance estimates derived from satellite gravimetry. In Antarctica the gravimetric effect of cryospheric mass change and GIA are of the same order of magnitude ...

Glacial Isostatic Adjustment Shapes Proglacial Lakes Over Glacial Cycles [PDF]

open access: yesGeophysical Research Letters, 2022
AbstractAs ice sheets load Earth's surface, they produce ice‐marginal depressions which, when filled with meltwater, become proglacial lakes. We include self‐consistently evolving proglacial lakes in a glacial isostatic adjustment (GIA) model and apply it to the Laurentide ice sheet over the last glacial cycle.

Glacial isostatic adjustment and post-seismic deformation in Antarctica [PDF]

open access: yesGeological Society, London, Memoirs, 2022
Abstract This chapter reviews glacial isostatic adjustment (GIA) and post-seismic deformation in Antarctica. It discusses numerical models and their inputs, and observations and inferences that have been made from them. Both processes are controlled by mantle viscosity but their forcings are different.

Reconstruction of North American drainage basins and river discharge since the Last Glacial Maximum [PDF]

open access: yesEarth Surface Dynamics, 2016
Over the last glacial cycle, ice sheets and the resultant glacial isostatic adjustment (GIA) rearranged river systems. As these riverine threads that tied the ice sheets to the sea were stretched, severed, and restructured, they also shrank and ...

Global NAVIGATION Satellite System Contribution for Observing the Tectonic Plate Movements: Status and Perspectives

open access: yesJournal of Engineering, 2023
The long-term monitoring of land movements represents the most successful application of the Global Navigation Satellite System (GNSS), particularly the Global Positioning System.

An approach for constraining mantle viscosities through assimilation of palaeo sea level data into a glacial isostatic adjustment model [PDF]

open access: yesNonlinear Processes in Geophysics, 2022
Glacial isostatic adjustment is largely governed by the rheological properties of the Earth's mantle. Large mass redistributions in the ocean–cryosphere system and the subsequent response of the viscoelastic Earth have led to dramatic sea level changes ...
