    dct:description "The East Styx electromagnetic, magnetic, and radiometric airborne geophysical survey is located about 150 kilometers northwest of Anchorage, Alaska in the upper Skwentna River drainage and surrounds the Rainy Pass Airport. The survey is in the Yentna, Redoubt, and McGrath mining districts of south-central Alaska. Frequency domain electromagnetic, magnetic, and radiometric data were collected with the DIGHEM system from June 24th to September 24th, 2013. A total of 7865.6 line kilometers were collected covering 2791.2 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 data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/30412." ;
