A well-studied example is the land uplift taking place in the Gulf of Bothnia, Fennoscandia, an area which was depressed by an ice sheet of 2 to 3 km thickness at the LGM. The ongoing adjustment following the ice sheet's retreat has been monitored by GPS studies, such as the Baseline Inferences for Fennoscandian Rebound Observations, Sea Level and Tectonics (BIFROST) project (Davis & members of BIFROST, 1996; Scherneck et al., 2003). The results determine the vertical and horizontal surface displacements, indicating land-uplift rates of up to 8 mm/a close to the former load centre. In contrast, the deformations in Antarctica has to be separated into recent ice-thickness changes and GIA induced vertical motion.
