Monitoring the surface movement of the Sørsdal Glacier, East Antarctica 2000–2001

Abstract

The Sørsdal Glacier, East Antarctica, offers an ideal study region to improve our understanding of glacier dynamics. The project ‘Structure and Dynamics of the Sørsdal Glacier’, which is funded by the Antarctic Science Advisory Committee (ASAC), aims to utilise various types of data collected on the Sørsdal Glacier over three summer field seasons, 2000–2003 to achieve this objective. The acquisition of reliable time-based positional information is vital for strain-rate computations and modelling purposes. This paper discusses aspects of the GPS surveying work undertaken in support of this project over the summer period 2000–2001.
