Radar-derived bed reflectivity of Rutford Ice Stream, West Antarctica, December 2016 to January 2017
GB/NERC/BAS/PDC/01438

Summary

Abstract:
The dataset presented here contains a csv-file including the coordinates, received power of the bed reflection and the two-way travel time of the bed reflection. The X and Y coordinates are projected in EPSG:3031 - WGS 84 / Antarctic Polar Stereographic coordinate system.
Data presented here have been frequency filtered and 2D migrated (using a finite difference approach and migration velocity of 0.168 m ns-1), followed by the picking of the bed reflection using ReflexW software (Sandmeier Scientific Software). The received power is calculated within a 280 ns time window centred on, and encompassing, the bed reflection (Gades et al., 2000).

This work was funded within the BEAMISH project by NERC AFI award numbers NE/G014159/1 and NE/G013187/1.
