资源简介：
GPR surveys were conducted using a Pulse Ekko Pro system, manufactured by Sensors and Software, with 500 MHz antennae. Surface common-offset measurements were collected using a trace spacing of 0.05 m and 16 stacks per trace. Transects were run over frozen soil in early June, 2010. Snow was removed to improve signal penetration. Based on common midpoint soundings, the velocity was 0.12 m/ns for the Old transects and 0.10 to 0.05 m/ns for the Young transects.
