Eagle Geophysical Survey

The Eagle airborne magnetic and radiometric geophysical survey covers parts of the Charley River, Eagle, and Tanacross quadrangles near Eagle, Alaska. Magnetic and radiometric data were collected with a fixed-wing aircraft May 24 to June 27, 2021 by MPX Geophysics LTD. A total of 26,926 line kilometers were collected covering 9,731 square kilometers. The magnetometer was mounted to a rear-facing fixed boom (tail stinger). The radiometric crystals were located in the cabin of the aircraft. The Eagle survey was flown with a line spacing of 400 meters (m) and a mean ground clearance of 330 m.
