Kasaan electromagnetic and magnetic airborne geophysical survey data compilation
Description
The Kaasan 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 in May 1992. A total of 679 line kilometers were collected covering 133.6 square kilometers. Line spacing was 200 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. The Kaasan survey was flown for the American Copper & Nickel Company, Inc. and provided to DGGS by the Sealaska Corporation. The data were merged and released with the 1999 Ketchikan geophysical survey maps. Map sheets and some of the other files in this data release contain data from adjacent or nearby surveys. The data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/30432.
