Abstract:
The postglacial rebound is component of the glacial isostatic adjustment which causes the Earth's crust to rebound in regions formerly covered by or adjacent to ice sheets, and subside beneath ocean basins. In North America, the observed postglacial rebound is mainly the result of the Laurentide Ice Sheet deglaciation after it reached its maximum thickness and extent at the Last Glacial Maximum (26.5-19 ka). Global-scale numerical models of glacial isostatic adjustment faithfully reproduce past and current changes in postglacial rebound, but the integration their predictions in a geographic information system to facilitate high-resolution paleotopographic reconstructions remains challenging. We therefore present high-resolution raster datasets of land-deformation and ice-free paleotopography of glaciated North America for several time slices since the Last Glacial Maximum to support geological, paleoenvironmental and archeological studies.
