Abstract
This dataset is comprised of ground penetrating radar data (GSSI DZT format with DZG files for GPS location) of a 28 square km area conduced in the heavily crevassed McMurdo Shear Zone in two consecutive field seasons. A radar system comprised of a GSSI SIR-30 32-bit two-channel control unit and model 5103 “400 MHz” and Model 5106A “200 MHz” antenna units were used to conduct the GPR surveys. The radar system was mounted on a sled and towed by a robot. The robot surveyed the 5 x 5.7 km area on lines separated by 50-m and traveled from West to East and return. The 2014 survey was conducted between Oct 29, 2014 and Nov 9, 2014, and the 2015 survey was conducted between Oct 26, 2015 and Nov 1, 2015. The use of identical waypoints in each year provides an Eulerian sampling protocol, where sampled GPS locations remain fixed, but the ice moves between annual surveys. In 2014, the 400 MHz antenna imaged to a depth of 19 meters, and in 2015, the 400 MHz antenna imaged to a depth of 80 meters to examine englacial ice. In both years, the 200 MHz antenna imaged to a depth of 160 meters.
