A new glacial isostatic adjustment model for Antarctica: calibrated and tested using observations of relative sea-level change and present-day uplift rates
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 …
