Nikolai electromagnetic and magnetic airborne geophysical survey data compilation

Metadata Updated: November 10, 2020

The Nikolai 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 Aerodat Condor system in 1995. A total of 3412.8 line kilometers were collected covering 660.1 square kilometers. Line spacing was 200 meters (m). Data were collected on a helicopter towed sensor platform ('bird') on a 30 m long line. The electromagnetic equipment recorded data slightly above 30 m above ground level (AGL), and the magnetometer recorded data slightly above 45 m AGL due to safety considerations. The Nikolai data were provided to DGGS by the U.S. Department of Interior Bureau of Land Management (BLM) and were merged with the Southern Delta River survey (2002) as a contract deliverable. The 2003 release of the Southern Delta River survey included map sheets of the merged data. The data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/30262.
