Ground Penetrating Radar data acquired over Von Postbreen, Svalbard, March 2018.

Ground-Penetrating Radar data acquired over Von Postbreen, Svalbard, to investigate the internal velocity structure by diffraction focusing. <br> Data authors: Richard Delf and Robert Bingham, University of Edinburgh. Data were acquired in March 2018 over 2 days.<br> Data were acquired with a PulseEkko Pro 25 MHz system, towed behind a snowscooter in an in-line, common-offset configuration. Data are stored in the SEGY format. <br> Differential GPS was used for positioning; coordinates are included in the SEGY data. Two groups of data are present here:<br> raw_data: filenames 18_VP_0_*_raw.SGY. <br> raw SEGY data as acquired. Significant ringing is present in this data as a result of the low offset between source and receiver. Data are organised by acquisition, with multiple passes over the glacier present in each file. <br> processed_data: filenames 18_VP_1_*.SGY<br> the same data as above, but with preprocessing applied to remove the aforementioned ringing. Data are subdivided into lines across and along the glacier.
