Iditarod Geophysical Survey

The Iditarod electromagnetic and magnetic airborne geophysical survey is located in the Iditarod, Innoko and McGrath mining districts, about 500 km southwest from Fairbanks, Alaska. The survey is adjacent to the Aniak, Beaver Creek, and Southern Dishna River geophysical surveys. Frequency domain electromagnetic and magnetic data were collected with the DIGHEMV system from August to September 2010. A total of 6,223.8 line kilometers were collected covering 2,244.5 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 survey was conducted by Fugro Airborne Surveys Corp. and administered by the Alaska Geological & Geophysical Surveys (DGGS).
