Description
The Bonnifield mining district electromagnetic and magnetic airborne geophysical survey area is located approximately 100 kilometers south of Fairbanks, Alaska. Frequency domain electromagnetic and magnetic data were collected with the DIGHEMV system from October 2nd, 2006, to February 2nd, 2007. A total of 4528 line kilometers were collected covering 1603 square kilometers (km). Line spacing was 400 meters (m). Data were collected an average of 36 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/10.14509/29557.
