Tofty Airborne Magnetic and Radiometric Survey, Alaska
Tofty airborne magnetic and radiometric survey, Alaska, Geophysical Report 2025-4, covers an area within the Tanana Quadrangle west of Fairbanks, Alaska. Magnetic and radiometric data were collected with a helicopter between August 25, 2024, and August 30, 2024, by EON Geosciences Inc. The survey contains a single block covering 298 km2. A total of 2,231.3 line-kilometers were collected. The magnetometer was installed inside the stinger attached to the helicopter nose. The airborne gamma-ray spectrometer was mounted on the interior floor of the helicopter cabin. The block was flown with a line spacing of 200 m, except for the northeastern portion of the block that was flown with a 100 m spacing. The nominal height of the survey was 134 m. Tie-lines for magnetic leveling were flown at 1,200 m spacing. The data, as well as additional metadata, are available from the DGGS website: https://doi.org/10.14509/31494
