• Project ID:

  1427

• Nickname/Abbreviation:

  Tanacross GP

• Parent Project:

  Geophysics Program

• Status:

  Complete

• Description:

  Airborne geophysical data for the Tanacross area were acquired and processed by Goldak Airborne Surveys under contract with the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys (DGGS). Project funded by the US Geological Survey, Mineral Resources Program. This high sensitivity aeromagnetic survey was carried out by Goldak Airborne Surveys (Goldak) on behalf of the Alaska Department of Geological and Geophysical Surveys (DGGS) between June 17th and July 31st, 2015. Aircraft equipment operated included three cesium vapor magnetometers, a GPS/GLONASS real-time and post-corrected differential positioning system, a flight path recovery camera, a digital video titling and recording system, as well as radar and barometric altimeters. All data were recorded digitally in GEDAS binary file format. Reference ground equipment included three GEM Systems GSM-19W Overhauser magnetometers and a Novatel 12 channel GPS/GLONASS base station which was set up at the base of operations for differential post-flight corrections. Forty-eight flights (including test and calibration sorties) were required to complete the survey block. A total of 26,533 line kilometers of high resolution magnetic data were collected, processed and plotted. The traverse lines were flown at a spacing of 500 meters with control lines flown at a separation of 5000 meters. Nominal terrain clearance was specified at 100 meters above ground. Tok, Alaska was used as the base of operations throughout the entire survey.
