Project Description
The TransAntarctic Mountains DeFormation Project (TAMDEF)is a
joint USGS and OSU program to measure crustal motion in the
Transantarctic Mountains of Southern Victoria Land.

Crustal movement is predicted as a result of variations in the
ice volume and loading of the East and West Antarctic Ice
Sheets through time. In addition we suspected there is active
tectonism associated with the Terror Rift, an offshore fault
zone that is nearby. There are also active volcanoes in the
region that may also be responsible for a measurable amount of
crustal deformation.
