Radar Investigations of Antarctic Ice Stream Margins, Siple Dome, 1998
Entry ID: NSIDC-0303

Abstract: This data set consists of surface-based radar measurements, including geometry of the bed, surface, and internal layers, and bed reflectivity measurements at two sites along ice stream margins at Siple Dome, Antarctica. The research is a radar examination of bed reflection characteristics and internal layer geometry in two inter-ice-stream ridges, the Shabtaie Ridge (Ridge D/E) and the Engelhardt ...

Quality Because the airwave signal swamps the first 1 �s of the data record, the first step in data processing is to remove the mean waveform from the profile to remove the airwave effect and reveal shallow layer information in the first 1 �s. Since the GPS data have not been fully processed, absolute error in vertical elevation could be as large as 50 m, so the displayed elevation scales for the radar profiles should be considered approximate. The profiles displayed in images are based on data files that have been subjected to demeaning and filtering and would therefore not be appropriate for any analyses directed toward accurate assessment of amplitude and phase without careful consideration.
