Project information
Project aim
This project will reassess the mass balance of Law Dome and a large sector of the Antarctic ice sheet south of Casey by exploiting the time history of change that can be obtained by resurveying historical surface elevation and gravity networks, started in the 1960s. The changes in position and gravity from these terrestrial traverses act as important constraints and, in some cases, calibration for recent satellite altimeter missions. Such a reassessment and model improvement should see a significant drop in the current uncertainty of the contribution of the Antarctic ice sheet to global sea level rise.
