Quad-polarimetric ApRES measurements along a 6 km-long transect at the WAIS Divide, December 2019
Polarimetric phase-sensitive radar measurements were collected at the Western Antarctic Ice Sheet (WAIS) Divide on the 25th and 26th December 2019. The measurements were conducted at 10 sites along a 6 km-long transect ~5-10 km northeast of the location of the WAIS Divide Deep Ice Core. At each site, a suite of four quadrature (quad-) polarimetric measurements were collected using an autonomous phase-sensitive radio echo sounder (ApRES) in a single-input single-output (SISO) configuration.
The study is part of the Thwaites Interdisciplinary Margin Evolution (TIME) project of the International Thwaites Glacier Collaboration (ITGC), and is a collaboration between the United States National Science Foundation (NSF) and the United Kingdom Natural Environment Research Council (NERC). It was funded by UK Natural Environment Research Council (NERC) research grant NE/S006788/1 and USA National Science Foundation (NSF) research grant 1739027.

- Statement
- The coarse-range (amplitude-derived) vertical (depth) resolution of the ApRES is 0.54 m. The azimuthal accuracy is unknown and is mainly the result of human error in alignment of antennas. A nominal azimuthal error of ±8° is assigned. The data included in this dataset are raw data and are entirely unprocessed.
