Alaska Division of Geological & Geophysical Surveys, in conjunction with the University of Alaska Fairbanks, Institute of Northern Engineering, Water and Environmental Research Center, managed the collection of frequency domain electromagnetic and magnetic data lines over a 200-square-kilometer portion of Western Yukon Flats, interior Alaska. Survey lines cover selected areas pertinent to the scope of research. The 301-line-kilometer survey was flown from February 25th to March 1st, 2016. Data were collected by CGG using the RESOLVE airborne geophysical survey system and measured 30m above the ground surface from a helicopter-towed sensor platform ('bird') on a 30-m-long line.
