Description
Summary:Complete, kinematic GPS profile along the route of the Norwegian-U.S. IPY traverse of East Antarctica. In addition static GPS measurements of snow stakes at selected locations along the route where made. The scientific objectives are to investigate surface topography and dynamics of the ice sheet, determine the spatial variability of the surface topography, validate remote sensing data, determine local topography around drill sites and to determine flow vectors at drill sites. Some of the stakes have been revisited, and some new stakes have been positioned. ### Route - Leg 1 (2007-2008): - **From:** Troll station [-72.01, 2.53] - **To:** "Camp Winter" [-86.8, 54.4] - Leg 2 (2008-2009): - **From:** South pole [-90, 0] - **Across:** Recovery lakes region - **To:** Troll station [-72.01, 2.53] ### Instruments - Trimble R7 dual-frequency GPS receiver - Trimble 5700 dual-frequency GPS receiver - Zephyr geodetic antennas **Calibration:** Both the Trimble R7 and Trimble 5700 dual-frequency GPS receivers where equipped with Zephyr Geodetic antennas set at 5 sec logging intervals, with Terrapos post-processing allowing high-level accuracy without base stations.
