Summary

Shallow subsurface electrical conductivity was mapped at Norman Lake National Wildlife Refuge (NWR) in northwest North Dakota using the DUALEM421 electromagnetic sensor (Dualem, Inc., ON, Canada) in the winter of 2018. 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 41 line-kilometers (km) of data were acquired over an area of approximately 2 square-kilometers. At this survey location, the 4m transmitter-receiver horizontal co-panar and perpendicular coil orientations did not function due to equipment malfunction. Data were manually edited to remove sensor dropouts, lag corrected for apparent [...]

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.
