Empirical estimation of present-day Antarctic glacial isostatic adjustment and ice mass change [PDF]

The Cryosphere, 2014
This study explores an approach that simultaneously estimates Antarctic mass balance and glacial isostatic adjustment (GIA) through the combination of satellite gravity and altimetry data sets. The results improve upon previous efforts by incorporating a

Glacial isostatic adjustment near the center of the former Patagonian Ice Sheet (48 degrees S) during the last 16.5 kyr

, 2022
Our understanding of glacial isostatic rebound across Patagonia is highly limited, despite its importance to constrain past ice volume estimates and better comprehend relative sea-level variations.

A dynamic continental runoff routing model applied to the last Northern Hemisphere deglaciation [PDF]

Geoscientific Model Development, 2012
We describe and evaluate a dynamical continental runoff routing model for the Northern Hemisphere that calculates the runoff pathways in response to topographic modifications due to changes in ice thickness and isostatic adjustment.

Reconstruction of ice-sheet changes in the Antarctic Peninsula since the Last Glacial Maximum [PDF]

, 2014
This paper compiles and reviews marine and terrestrial data constraining the dimensions and configuration of the Antarctic Peninsula Ice Sheet (APIS) from the Last Glacial Maximum (LGM) through deglaciation to the present day.

ICESHEET 1.0: a program to produce paleo-ice sheet reconstructions with minimal assumptions [PDF]

Geoscientific Model Development, 2016
We describe a program that produces paleo-ice sheet reconstructions using an assumption of steady-state, perfectly plastic ice flow behaviour. It incorporates three input parameters: ice margin, basal shear stress and basal topography.

Comparison of the glacial isostatic adjustment behaviour in glacially induced fault models [PDF]

, 2016
Abstract. We compare the glacial isostatic adjustment (GIA) behaviour of two approaches developed to model the movement of a glacially induced fault (GIF) as a consequence of stress changes in the Earth's crust caused by the GIA process. GIFs were most likely, but not exclusively reactivated at the end of the last glaciation.

Anomalous secular sea-level acceleration in the Baltic Sea caused by isostatic adjustment

Annals of Geophysics, 2014
Observations from the global array of tide gauges show that global sea-level has been rising at an average rate of 1.5-2 mm/yr during the last ~150 years [Douglas 1991, Spada and Galassi 2012]. Although a global sea-level acceleration was initially ruled

Dynamic hydrological discharge modelling for coupled climate model simulations of the last glacial cycle: the MPI-DynamicHD model version 3.0 [PDF]

Geoscientific Model Development, 2018
The continually evolving large ice sheets present in the Northern Hemisphere during the last glacial cycle caused significant changes to river pathways both through directly blocking rivers and through glacial isostatic adjustment.

Research Article. A new gravity laboratory in Ny-Ålesund, Svalbard

Journal of Geodetic Science, 2017
The Norwegian Mapping Authority (NMA) has recently established a new gravity laboratory in Ny-Ålesund at Svalbard, Norway. The laboratory consists of three independent pillars and is part of the geodetic core station that is presently under construction ...

Glacial-Isostatic Adjustment-I. The Forward Problem [PDF]

Geophysical Journal of the Royal Astronomical Society, 2007
Summary The isostatic adjustment of a radially stratified visco-elastic spheroid is treated using space-time Green functions for the associated surface mass load boundary value problem. These impulse response functions are convolved with a Heaviside function to give the time dependent deformation of the planet which would be produced by a unit point
