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...
