Surface Nuclear Magnetic Resonance and Time-Domain Electromagnetic data in the Camas Prairie near Fairfield, south-central Idaho

In cooperation with the Idaho Department of Water Resources (IDWR), the U.S. Geological Survey, (USGS), collected surface nuclear magnetic resonance (sNMR) and time-domain electromagnetic (TDEM) surveys at eight sites located in the Camas Prairie, Idaho between July 30 and August 2, 2024. The data were acquired to characterize the subsurface and define hydraulic properties of the shallow, unconfined aquifer. sNMR data were collected with a Vista Clara GMR flex unit using a 70-meter diameter circle signal loop (Tx/Rx) and an approximately 50-meter diameter circle noise loop. TDEM data were collected with an ABEM WalkTEM unit using a 40-by-40 meter square transmitted loop and a 0.5-by-0.5 meter square center receiver loop (Rx). Multiple surveys collected at the same location were stacked, filtered, and averaged. This data release includes the raw and processed sNMR and TDEM data.
