Modeling of the northern hemisphere ice sheets during the last glacial cycle and glaciological sensitivity [PDF]
, 2005 We present a new three-dimensional thermomechanically coupled ice sheet model of the northern hemisphere to reconstruct the Quaternary ice sheets during the last glacial cycle.

Glacial isostatic adjustment modelling: historical perspectives, recent advances, and future directions [PDF]
Earth Surface Dynamics, 2018 Glacial isostatic adjustment (GIA) describes the response of the solid Earth, the gravitational field, and the oceans to the growth and decay of the global ice sheets.

Inferences of mantle viscosity based on ice age data sets: Radial structure [PDF]
, 2016 We perform joint nonlinear inversions of glacial isostatic adjustment (GIA) data, including the following: postglacial decay times in Canada and Scandinavia, the Fennoscandian relaxation spectrum (FRS), late-Holocene differential sea level (DSL ...

Emergence of the Shackleton Range from beneath the Antarctic Ice Sheet due to glacial erosion [PDF]
, 2014 This paper explores the long-term evolution of a subglacial fjord landscape in the Shackleton Range, Antarctica. We propose that prolonged ice-sheet erosion across a passive continental margin caused troughs to deepen and lower the surrounding ice-sheet ...

Joint inversion estimate of regional glacial isostatic adjustment in Antarctica considering a lateral varying Earth structure (ESA STSE Project REGINA) [PDF]
, 2017 A major uncertainty in determining the mass balance of the Antarctic ice sheet from measurements of satellite gravimetry, and to a lesser extent satellite altimetry, is the poorly known correction for the ongoing deformation of the solid Earth caused by

Glacial isostatic adjustment on a rotating earth [PDF]
Geophysical Journal International, 2001 SUMMARY We extend and complete previous work to compute the influence of perturbations to the rotation vector on a suite of observables associated with glacial isostatic adjustment (GIA). We emphasize observables relevant to present and future geodetic missions (for example, present-day 3-D crustal motions, relative sea-level change and geoid or ...

The glacial systems model (GSM) Version 25G [PDF]
Geoscientific Model DevelopmentWe document the glacial system model (GSM), which is designed for large ensemble ice sheet modelling in glacial cycle contexts. A distinguishing feature is the extent to which it addresses relevant forcing and process uncertainties. The GSM has evolved

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
