Abstract:
Radar profiles of the upper 50-90 m of the snowpack along the route of the Norwegian-U.S. IPY traverse of East Antarctica. The radar was run primarily as a crevasse detector, but the data has been kept for comparison with other radar data from the traverse. The scientific objectives are to investigate the spatial and temporal variability in snow accumulation over this area of Antarctica, and to validate remote sensing data.
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
- GSSI TerraSIRch 3000 ground penetrating radar, with 400 MHz antenna
Quality
Due to instrument limitations the profiles are not continuous. The instrument allows a maximum file size of 64 MB, thus the profiles were interrupted for data storage every few km. Instrument settings also vary along the track.
