Description:
The Ketchikan geophysical survey is located in southeast Alaska in the Ketchikan area, about 350 kilometers south of Juneau, Alaska. Frequency domain electromagnetic and magnetic data were collected with the DIGHEMV system from February to April 1999. A total of 4750.8 line kilometers were collected covering 1648.6 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. In the original 1999 release the Ketchikan survey was merged with data from several adjacent surveys (Kasaan, Hetta, and Dolomi). Map sheets and some of the other files in this data release contain data from adjacent or nearby surveys.
