Goldstream Valley Geophysical Survey

A National Science Foundation grant to study Arctic hydrology-permafrost-methane systems was awarded to the University of Alaska Fairbanks (UAF), Institute of Northern Engineering, Water and Environmental Research Center with the Alaska Division of Geological & Geophysical Surveys (DGGS) as a co-investigator. As part of the study, DGGS managed the collection, modeling, and interpretation of airborne electromagnetic and magnetic data over a 258-square-km portion of the Goldstream Creek watershed, interior Alaska. The survey was flown from March 6th to March 17th, 2016 by CGG using their RESOLVE airborne geophysical system with a line spacing of either 100 meters (m) or 200 m; additional custom lines were collected over areas of scientific interest. The data were measured from 30 m above the ground surface using a helicopter-towed sensor platform ('bird') on a 30-m long line. Users can access the data and metadata below.
