Kuskokwim airborne magnetic and radiometric survey, Sischu Mountains

Description

Kuskokwim airborne magnetic and radiometric survey, Sischu Mountains, Geophysical Report 2024-1, covers parts of the Ruby, Kantishna River, Mt. McKinley, Medfra, and Ophir quadrangles north of McGrath, Alaska. Magnetic and radiometric data were collected with a helicopter between July 14, 2023, and October 15, 2023, by Geotech Ltd. The survey contains a single block covering 8,008 km2. A total of 25,878 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 400 m. The mean ground clearance is 192 m with a nominal survey speed of 142 km/hour. The data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/31094.
