The TAMDEF project is a joint OSU and USGS program to measure bedrock motion in the Transantarctic Mountains of Southern Victoria Land.
The bedrock is slowly moving in response to changes in the mass of the Antarctic Ice Sheets. As the weight of the ice sheets changes the Earths surface bends and the mantle flows to accomodate the new ice configuration.
We are also measuring the tectonic motion over the nearby Terror Rift, an offshore zone of faulting.
We use precision GPS measurements separated by several years to test the predicted rates of motion. The eighth and final seasons of measurement was completed in 2006, in this the most extensive ice-free area on the Antarctic continent.
