Space geodesy constrains ice age terminal deglaciation: The global ICE‐6G_C (VM5a) model

Abstract A new model of the last deglaciation event of the Late Quaternary ice age is here described and denoted as ICE‐6G_C (VM5a). It differs from previously published models in this sequence in that it has been explicitly refined by applying all of the available Global Positioning System (GPS) measurements of vertical motion of the crust that may be brought to bear to constrain the thickness of local ice cover as well as the timing of its removal. Additional space geodetic constraints have also been applied to specify the reference frame within which the GPS data are described. The focus of the paper is upon the three main regions of Last Glacial Maximum ice cover, namely, North America, Northwestern…
