Online_Linkage: https://doi.org/10.14509/31087 Description: Abstract: Kuskokwim airborne magnetic and radiometric geophysical survey, northern Kuskokwim Mountains, Geophysical Report 2023-1, covers parts of the Tanana, Norton Bay, Nulato, Ruby, Kantishna River, Medfra, and Mt. McKinley quadrangles west of Nenana, Alaska (fig. 1). Magnetic and radiometric data were collected with a fixed-wing aircraft from May 14 to August 31, 2023, by MPX Geophysics LTD. The survey contains a single block. A total of 86,712 line-kilometers were collected. The block covers 29,361 km2. The magnetometer was mounted to a rear-facing fixed boom ("tail stinger"). The radiometric crystals were located in the cabin of the aircraft. The block was flown with a line spacing of 400 m. The mean ground clearance is 184 m. The data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/31087. Purpose: The data from the Kuskokwim airborne magnetic and radiometric survey, northern Kuskokwim Mountains geophysical survey will be used to improve the understanding of the area's geology and mineral potential and promote resource exploration. This survey will also be a part of planned continuous regional magnetic data coverage of the greater Kuskokwim Mountains region.
