Project aim

The present-day observed change in sea level is the sum of several factors, including the continuing readjustment of the crust to the past redistribution of the surface ice-water load and any present-day melting of the Antarctic ice sheet. Constraints can be provided on both of these contributions by measuring the magnitude of the crustal rebound using the Global Positioning System. By combining the measurements with other estimates of sea-level change, it becomes possible to separate the two contributions. This will lead to both improved mass balance models for the ice-ocean system and improved understanding of present sea-level change.
