Stikine Geophysical Survey

The Stikine geophysical survey is located in southeast Alaska near the city of Wrangell, about 175 kilometers south of Juneau, Alaska. Frequency domain electromagnetic and magnetic data were collected with the DIGHEMV system from March to May 1997. A total of 8,097 line kilometers were collected covering 2,870.1 square kilometers. Line spacing was 400 meters (m). Data were collected approximately 30 m above the ground cover or tree canopy from a helicopter-towed sensor platform ("bird") on a 30-m-long line. The large trees and steep terrain resulted in an average ground clearance of 150 m.
