Project information
Project aim
The project will involve making a series of measurements of the Amery ice-sheet topography using static and kinematic GPS observations, aircraft laser profiling and measurements made from the new generation of satellite geoscience laser altimeter system (GLAS). The measurements of the ice sheet topography will be made near-simultaneously (within 8-16 days) from the in-situ systems to assess the error budgets of the GLAS satellite. The overall goal of the project is to determine the seasonal and interannual variation in surface elevation of the Antarctic ice sheet. This information is essential for predicting future changes in ice volume and sea-level and the state of balance of the ice sheet.

We report on long-term surface elevation changes of the central Amery Ice Shelf … (AIS) by comparing elevation records spanning 4 decades (1968–2007). We use elevation … records acquired with the following methods: optical leveling (1968–1969); ERS … radar altimetry (1992–2003); GPS (1995–2006)…
