Broad Pass electromagnetic and magnetic airborne geophysical survey data compilation

This Broad Pass electromagnetic and magnetic airborne geophysical survey is located in interior Alaska in the Bonnifield mining district, about 160 kilometers south of Fairbanks, Alaska and about 250 kilometers north of Anchorage, Alaska. Frequency domain electromagnetic and magnetic data were collected with the DIGHEMV system from July to August 2001. A total of 1970.2 line kilometers were collected covering 689.5 square kilometers. Line spacing was 400 meters (m). Data were collected 30 m above the ground surface from a helicopter towed sensor platform ('bird') on a 30 m long line. The data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/30415.
