Processed bed elevation picks from airborne radar depth sounding over the Jutulstraumen rift area (2001/02 season)
A British Antarctic Survey Twin Otter and survey team acquired 15,500 line-km of aerogeophysical data during the 2001/02 Antarctic field season along a 1-km line spacing grid with tie-lines 8 km apart. Twenty-five flights were flown from the South African base SANAE, for a total of 100 survey hours. We present here the processed bed elevation picks from airborne radar depth sounding. The airborne-radio echosounding data were collected for 5 flights, to image ice-thickness and bedrock configuration.
Data are provided as XYZ ASCII line data. This high-resolution aerogeophysical survey was part of the "Magmatism as a Monitor of Gondwanabreak-up" project (MAMOG) of the British Antarctic Survey, which included new geochemical investigations, structural geology, geochronology, and AMS studies over western Dronning Maud Land.

Methodology:
Radar data presented in Ferraccioli et al (2005).The airborne ice sounding radar system used was the "BAS-built" system, which operated a 4 us linear frequency modulated pulse in addition to a standard short 0.25 us pulse (Corr and Popple, 1994; Fremand, Bodart et al., 2022). Data provided here includes picked ice sheet bed elevation along exploratory or longer transit lines. No radar data was collected from the main survey grid.

surfElev Surface elevation. BEDMAP2 surface used here. (m)
bedElev Ice bed elevation, derived by subtracting tice from surfElev (m)
tIce Ice thickness (m).
*Projected coordinates (x and y) are in Lambert conic conformal with two standard parallels defined as follows:
Latitude of natural origin: -71
Longitude of natural origin: 0
Scale factor at natural origin -75.33333333333
False easting 0
False northing 2082760.109
Data quality:
The following parameters have no values: Height_WGS1984, SegY_name, TraceNum, PriNum, surfPickloc, bedPickloc.
Date information is not available and is missing. The campaign took place between January and February 2002.
