Nield, Grace A. (author), Whitehouse, Pippa L. (author), van der Wal, W. (author), Blank, B. (author), O'Donnell, John Paul (author), Stuart, Graham W. (author)Differences in predictions of Glacial Isostatic Adjustment (GIA) for Antarctica persist due to uncertainties in deglacial history and Earth rheology. The Earth models adopted in many GIA studies are defined by parameters that vary in the radial direction only and represent a global average Earth structure (referred to as 1-D Earth models)....journal article 2018

Van der Wal, W. (author), Whitehouse, P.L. (author), Schrama, E.J.O. (author)Seismic data indicate that there are large viscosity variations in the mantle beneath Antarctica. Consideration of such variations would affect predictions of models of Glacial Isostatic Adjustment (GIA), which are used to correct satellite measurements of ice mass change. However, most GIA models used for that purpose have assumed the mantle to...journal article 2015

(author), Clarke, P.J. (author), King, E.C. (author), Hindmarch, R.C.A. (author), Koivula, H. (author)Bedrock uplift in Antarctica is dominated by a combination of glacial isostatic adjustment (GIA) and elastic response to contemporary mass change. Here, we present spatially extensive GPS observations of Antarctic bedrock uplift, using 52% more stations than previous studies, giving enhanced coverage, and with improved precision. We observe...journal article 2011
