The Richardson electromagnetic and magnetic airborne geophysical survey is located in interior Alaska in the Richardson mining district, about 65 kilometers southeast of Fairbanks, Alaska. Frequency domain electromagnetic and magnetic data were collected with the DIGHEMV system in August 1994. A total of 1094.0 line kilometers were collected covering 400.0 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 survey data were aquired and/or processed by Dighem and WGM, Inc and administered by the Alaska Geological & Geophysical Surveys (DGGS).
