Southern Dishna River geophysics
Nickname/Abbreviation:Southern Dishna River GP
Description:The Southern Dishna River survey is one of several geophysical surveys, collectively known as the Five Spot project (Southern Dishna River, Beaver Creek, and Fox Hills surveys), located in the Iditarod-Innoko and Aniak mining districts, which is about 575 km southwest from Fairbanks, Alaska. Frequency domain electromagnetic and magnetic data were collected with the DIGHEMV system from September to November 2012. A total of 4546.9 line kilometers were collected covering 1614.9 square kilometers for the Southern Dishna River survey. Line spacing was 400 meters (m). Data were collected 30 m above the ground surface from a helicopter towed sensor platform ('bird') on a 30 m long line.
