Airborne radar bed elevation along flow lines covering the Evans, and Rutford Ice Streams, and ice rises in the Ronne Ice Shelf (2006/07)
An airborne radar survey was flown as part of the GRADES-IMAGE project funded by BAS over the Evans Ice stream/Carson Inlet region mainly to image englacial layers and bedrock topography during the 2006/07 field season. Aeromagnetic data were also opportunistically collected.
We present here the bed elevation picks from airborne radar depth sounding collected using the BAS PASIN radar depth sounding system.
Data are provided as XYZ ASCII line data.

Methodology:
Radar data were collected using the PASIN radar echo sounding system. Data provided here includes picks of surface and ice sheet bed elevation. Note a single flight may contain data from two or more SEGY files, identified in the SEGYname channel. Surface elevation is derived from radar altimeter for ground clearance < 750 m, and the PASIN system for higher altitudes.

*Projected coordinates (x and y) are in Polar Stereographic:
Latitude of natural origin: -71
Longitude of natural origin: 0
Scale factor at natural origin: 0.994
False easting 0
