Glacial Isostatic Adjustment (GIA) in Greenland: a Review [PDF]
Current Climate Change Reports, 2016 Using the most recently published regional and global deglaciation histories we provide updated estimates of the Glacial Isostatic Adjustment (GIA) component of present day uplift at a suite of GPS sites in Greenland. The GIA of the solid Earth beneath Greenland contributes -6 to +10 Gt/yr to the present day mass trends observed by the Gravity Recovery

Glacial isostatic adjustment directed incision of the Channeled Scabland by Ice Age megafloods. [PDF]
Proc Natl Acad Sci U S A, 2022 During the last deglaciation, dozens of glacial outburst floods-among the largest known floods on Earth-scoured the Channeled Scabland landscape of eastern Washington.

Contribution of glacial-isostatic adjustment to the geocenter motion [PDF]
Tectonophysics, 2011 Abstract The geocenter motion describes the surface net-displacement of the entire solid Earth with respect to the center-of-mass of the entire Earth including surface masses. Therefore, it resembles an integrative quantity of surface displacement and mass redistribution inside the Earth as well as at its surface. Seasonal variations of this quantity

Uncertainty in Greenland glacial isostatic adjustment [PDF]
, 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 ...

Impact of glacial isostatic adjustment on cosmogenic surface-exposure dating [PDF]
Quaternary Science Reviews, 2019 Calculating cosmogenic-nuclide surface-exposure ages is critically dependent on a knowledge of the altitude of the sample site. Changes in altitude have occurred through time as a result of glacial isostatic adjustment (GIA), potentially altering local nuclide production rates and, therefore, surface-exposure ages.

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

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

A new powder encapsulation method and its implications on densification by hot isostatic pressing [PDF]
, 1993 Hot isostatic pressing is now an accepted material processing technique for the consolidation of metal powders to near-net-shape components. This thesis examines the use of coatings as in-situ envelopes to overcome the problems associated with ...

Numerical methods for glacial isostatic adjustment models
, 2013 Nordic countries experience post-glacial rebound, a movement where geographical contours slowly change elevation with respect to the mean sea level. The glacial isostatic adjustment (GIA) model aims to explain the phenomena, which combined with seismic data allows geoscientists to reconstruct elastic coefficients and viscosities of the Earth's ...
