Project information
Project aim
The project will involve making a series of measurements on the Amery Ice Shelf using GPS static and kinematic procedures to determine the vertical displacements of the ice shelf as a function of time. The GPS-determined displacements will be compared to tidal elevations computed from barotropic tide models and other hydrodynamic models. The overall goal of the project is to better understand the ice shelf-ocean interaction. This information is essential for predicting future changes in the ice volume and sea-level.
