The Southern Delta River electromagnetic and magnetic airborne geophysical survey is located in interior Alaska in the Delta River mining district, about 200 kilometers southeast of Fairbanks. Frequency domain electromagnetic and magnetic data were collected with the DIGHEMV system from August to September 2002. A total of 2,902.8 line kilometers were collected covering 1001 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 and Stevens Exploration Management Corp. and administered by the Alaska Geological & Geophysical Surveys (DGGS).
