Summary

This data release presents raw (.csv) and processed (.csv) data files from land-based, frequency-domain electromagnetic induction (EMI) data collected at Bicycle Basin, U.S. Army Fort Irwin National Training Center, California. Data were collected during three distinct time periods: March 19, 2008 (1 survey), December 1 to December 5, 2014 (46 surveys) and December 4 to December 8, 2015 (62 surveys). Data were collected by walking along survey lines throughout the airstrip region of the basin with the Geophex GEM-2 instrument at a height of approximately 1 meter above land surface in horizontal coplanar (ski flat) mode. The EMI data were used to map variations in subsurface electrical conductivity to investigate ground failures in [...]

Purpose

Electromagnetic induction (EMI) data were used to map variations in subsurface electrical conductivity to investigate ground failures in the form of large surface cracks that have occurred in the airstrip region of the basin, and to infer the possible occurrence of voids in the subsurface that may pose risk of future ground failures.
