Summary

Shallow subsurface electrical conductivity was mapped at Stateline National Wildlife Refuge (NWR) in northeast Montana using the DUALEM421 electromagnetic sensor (Dualem, Inc., ON, Canada) in the winter of 2017. Data were acquired by towing the DUALEM421 sensor on a sled behind an all-terrain vehicle or snow machine, with the sensor at a nominal height of 0.3 meters (m) above ground surface. Approximately 3 line-kilometers (km) of data were acquired over an area of approximately .2 square-kilometers. Data were manually edited to remove sensor dropouts, lag corrected for apparent offsets between recorded GPS location and data locations for each coil pair, and averaged to a sounding distance of 1m along the survey path; data were not [...]

Purpose

Historical oil and gas development on or adjacent to some U.S. Fish and Wildlife Service managed lands has resulted in saline contamination of surface and groundwater resources. At some locations, the extent and magnitude of contamination has been previously documented whereas at other areas, the extent of potential contamination is unknown. These data were collected to establish the electrical conductivity patterns that may be associated with changes in shallow salinity at selected U.S. Fish and Wildlife Service managed lands.
