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

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