The Antarctica component of postglacial rebound model ICE-6GC (VM5a) based on GPS positioning, exposure age dating of ice thicknesses, and relative sea level histories

A new model of the deglaciation history of Antarctica over the past 25 kyr has been developed, which we refer to herein as ICE-6GC (VM5a). This revision of its predecessor ICE-5G (VM2) has been constrained to fit all available geological and geodetic observations, consisting of:
