Global Positioning System (GPS) data, Rutford Ice Stream, West Antarctica, 2004-2006

Summary

Abstract:
GPS positioning data monitoring ice flow during the RABID project. Data were collected using Leica and Trimble receivers at five sites ~40km upstream from the grounding line of Rutford Ice Stream, with four of these sites ~3km upstream, downstream and in both directions across the ice stream from the central GPS. To improve the accuracy of the data from the ice stream GPS network, two base stations were established adjacent to the ice stream; one GPS receiver was installed on the slow-moving adjacent ice sheet (Fletcher Promontory), and one on 'Tolly's Heel' nunatak (unofficial place name) in the Ellsworth Mountains. The data were collected from 17 December 2004 to 10 February 2005 for the five main stations, with the reference GPS measuring from 31 December to 3 February. All the GPS receivers recorded data at 10s intervals.

The RABID project employed hot-water drilling techniques, down-hole instrumentation, as well as surface geophysical measurements, to form an integrated programme studying ice dynamics, basal conditions, climate and glacial history.

Funding was provided by the UK NERC Antarctic Funding Initiative (AFI).
