Livengood mining district electromagnetic and magnetic airborne geophysical survey, data compilation

The Livengood electromagnetic and magnetic airborne geophysical survey data were acquired with a DIGHEM-V Electromagnetic (EM) system and a cesium magnetometer. The EM and magnetic sensors were flown at a height of 30 meters (m). In addition the survey recorded data from radar and laser altimeters, a GPS navigation system, 50/60 Hz monitors and a video camera. Flights were performed with an AS-350-B2 Squirrel helicopter at a mean terrain clearance of 60 m along N-S survey flight lines with a spacing of 400 m. Tie lines were flown perpendicular to the flight lines at intervals of approximately 4,800 m

Geothermal Resources of Alaska

Between 1979 and 1982, the Alaska Division of Geological & Geophysical Surveys (DGGS) and the Geophysical Institute, University of Alaska Fairbanks, undertook an assessment of the states geothermal resources under a program jointly sponsored by the U.S. Department of Energy and the State of Alaska. During this period, reconnaissance investigations of more than 100 thermal spring sites and fumarole fields located in Alaska were conducted by DGGS.

White Mountains Airborne Magnetic and Radiometric Geophysical Survey

The White Mountains airborne magnetic and radiometric geophysical survey covers parts of the Livengood, Circle, and Fairbanks quadrangles 25 kilometers north of Fairbanks, Alaska. Magnetic and radiometric data were collected with a fixed-wing aircraft June 30 to August 22, 2021 by MPX Geophysics LTD. A total of 36,933 line kilometers were collected covering 13,423 square kilometers. The magnetometer was mounted to a rear-facing fixed boom (tail stinger). The radiometric crystals were located in the cabin of the aircraft. The White Mountains survey was flown with a line spacing of 400 meters (m) and a mean ground clearance of 270 m. The data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/30756....

Yukon-Tanana Upland airborne magnetic geophysical data merge, version 2023

The Yukon-Tanana Upland airborne magnetic geophysical data merge provides a merged raster grid of magnetic data for the Yukon-Tanana Upland (YTU), Alaska. This dataset provides a regionally consistent magnetic grid while retaining as much detail as possible of the originating data by leveling all the region's magnetic grids to one another. This 100-m cell-size magnetic grid of the YTU will assist in evaluating the region's geologic structure, geologic processes, tectonic evolution, and mineral resource potential. The grid was compiled from previous studies published by the Alaska Division of Geological & Geophysical Surveys (DGGS).
