Airborne magnetic geophysical survey of the Porcupine River area, Alaska

The Porcupine River fixed wing aeromagnetic geophysical survey is located in eastern Alaska, along the Canadian border, in the Sheenjek and Black mining districts. This survey is located about 135 kilometers east of Fort Yukon, Alaska and about 85 kilometers east of Circle, Alaska. Magnetic data were collected with a Geometrics G-822A cesium-vapor split-beam sensor mounted in a tail stinger. Between May 5th and June 28th, 2017, a total of 50,329 line kilometers were collected covering 13,646.9 square kilometers. Data were collected at a line spacing of 300 meters (m) with a mean ground clearance of 235 m. The data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/29737.
