Ice sheet model runs simulating former ice sheet configurations in the Weddell Sea embayment
GB/NERC/BAS/PDC/00570
Abstract:
Ice sheet model runs based on the Glimmer thermo-mechanical ice sheet model. Glacial modelling was used to simulate former WAIS (West Antarctic Ice Sheet) dynamics (specifically grounding line and ice volume changes) in the Weddell Sea embayment, constrained by newly acquired field data (see related datasets).
