Prediction of Sea Level Change around Australia and its Calibration and Validation by Satellite-Geodetic Measurements

The redistribution of mass and loading due to deglaciation will change the gravity field, spin axis and centre of mass of the Earth. As such, global sea level will not rise by the same amount in all places, and will even fall in some. This project will extend our realistic Earth model, constructed from a previous ARC grant, to simulate such changes in sea level. These simulated values will be compared with contemporary estimates of ice mass balance and temporal gravity changes measured by satellite geodesy. Ultimately, this will allow for more informed management of sea level change in Australasia.
