Dolomi electromagnetic and magnetic airborne geophysical survey data compilation

Description

The Dolomi 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 March 1991. A total of 415 line kilometers were collected covering 81.2 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 Dolomi survey was flown for the American Copper & Nickel Company, Inc. and provided to DGGS by provided 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/10.14509/30431.
