Description
Summary:Summary The Transantarctic Mountains Deformation (TAMDEF) network is a GPS array deployed on bedrock throughout the Victoria Land region of Antarctica, aimed at investigating modern vertical and horizontal crustal motions. Embedded within this network are three local GPS arrays established around known or potential neotectonic faults to test for modern fault displacements. These local fault arrays were surveyed a minimum of three times between the 1996-97 and 2005-06 austral summer field seasons. Preliminary analysis of baseline length changes is consistent with active extension, suggesting there may be modern tectonic activity in the West Antarctic Rift System.
