Paleo-ice sheet reconstructions constrained by GIA and geological data for use in climate models [PDF]

, 2017
Paleo-ice sheet reconstructions are complicated by large uncertainties, particularly since it is usually only possible to infer thickness from indirect means such as the response of glacial isostatic adjustment (GIA).

Application of TOPEX Altimetry for Solid Earth Deformation Studies

Terrestrial, Atmospheric and Oceanic Sciences, 2008
This study demonstrates the use of satellite radar altimetry to detect solid Earth deformation signals such as Glacial Isostatic Adjustment (GIA). Our study region covers moderately flat land surfaces seasonally covered by snow/ice/vegetation.

A simple physical model for glacial cycles [PDF]

Earth System Dynamics
Glacial cycles are the norm in Pleistocene climate variability. Models of varying degree of complexity have been used to answer the question of what causes the nonlinear response of the climate system to the periodic forcing from the Sun.

Uncertainty in Greenland glacial isostatic adjustment

, 2013
It is well known that the interpretation of geodetic data in Greenland to constrain recent ice mass changes requires knowledge of isostatic land motion associated with past changes in the ice sheet. In this talk we will consider a variety of factors that limit how well the signal due to past mass changes (commonly referred to as glacial isostatic ...

Ocean mass from GRACE and glacial isostatic adjustment

Journal of Geophysical Research: Solid Earth, 2010
We examine geoid rates and ocean mass corrections from two published global glacial isostatic adjustment (GIA) models, both of which have been used in previous studies to estimate ocean mass trends from Gravity Recovery and Climate Experiment (GRACE) satellite gravity data.

Globally consistent estimates of high-resolution Antarctic ice mass balance and spatially resolved glacial isostatic adjustment [PDF]

The Cryosphere
A detailed understanding of how the Antarctic ice sheet (AIS) responds to a warming climate is needed because it will most likely increase the rate of global mean sea level rise.

Tectonics of the central Andes [PDF]

Acquisition of nearly complete coverage of Thematic Mapper data for the central Andes between about 15 to 34 degrees S has stimulated a comprehensive and unprecedented study of the interaction of tectonics and climate in a young and actively developing ...

Earth responses to ice mass changing in iceland [PDF]

, 2010
The reological properties of the crust and the upper mantle beneath Iceland make the earth surface sensitive to recent ice mass changing. On a short time scale, strong correlation exists between seasonal variations in continuous GPS time series and snow ...

How and Why to do VLBI on GPS [PDF]

, 2010
In order to establish the position of the center of mass of the Earth in the International Celestial Reference Frame, observations of the Global Positioning Satellite (GPS) constellation using the IVS network are important.
