The Goldstream geophysical survey dataset provides airborne electromagnetic and magnetic data and resistivity models from 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 Canada Ltd. using their RESOLVE airborne geophysical system. Survey line spacing was 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. The geophysical survey provides a snapshot of subsurface electromagnetic and magnetic variability throughout the study area. The data and resistivity modeling facilitates interpretation of surface and subsurface features and processes within Goldstream Valley and surrounding areas of interior Alaska. The Goldstream Valley Watershed project is funded by the National Science Foundation, Office of Polar Programs, Arctic System Science Program, award #1500931.
