We present a glacial isostatic adjustment (GIA) model for Antarctica. This is driven by a new
deglaciation history that has been developed using a numerical ice-sheet model, and is
constrained to fit observations of past ice extent. We test the sensitivity of the GIA model to
uncertainties in the deglaciation history, and seek earth model parameters that minimize the
misfit of model predictions to relative sea-level observations from Antarctica. We find that the
relative sea-level predictions are fairly insensitive to changes in lithospheric thickness and …

We present a glacial isostatic adjustment (GIA) model which is based on a new
reconstruction of ice mass changes in Antarctica during the last glacial cycle. The ice sheet
reconstruction was constrained using a continent-wide dataset of glacial geological and
glaciological data, and generated using a numerical ice sheet model driven by spatial and
temporal variations in temperature and accumulation rate. This reconstruction of the
Antarctic ice sheet was then incorporated into a global history of ice mass change in order to …
