Fortymile mining district electromagnetic and magnetic airborne geophysical survey, data compilation
The Fortymile 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
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...

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
Merged grids of residual magnetic intensity, digital terrain model, and apparent resistivity compiled from the Black Mountain, Liscum, Goodpaster, SE extension of Salcha River - Pogo, and Salcha River Pogo geophysical surveys.
Frequency domain electromagnetic data and magnetic geophysical data were collected below a helicopter using a 30 meter (m) long line and a towed bird for the 1997 Iron Creek survey. The geophysical data were acquired with a DIGHEM-V Electromagnetic (EM) system, a Scintrex cesium magnetometer, and a Herz VLF system installed in on AS350B-2 Squirrel helicopter. In addition, the survey recorded data from a radar altimeter, GPS navigation system, 50/60 Hz monitors and video camera. Many of the files for this release were published on paper and available by mail order beginning in 1998. This updated data release provides a compilation of the previously published paper files (in PDF format) and the originating data files...
The Tonsina electromagnetic and magnetic airborne geophysical survey data were acquired with a DIGHEMv Electromagnetic (EM) system and a CGG D1344 cesium magnetometer with a Scintrex CS3 cesium sensor. 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, GPS navigation system, 50/60 Hz monitors and video camera. Flights were performed with an AS-350-B3 Squirrel helicopter at a mean terrain clearance of 60 m along NW-SE (345 degrees) 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. These data were produced under contract between the State of...
The Tok electromagnetic and magnetic airborne geophysical survey data were acquired with a DIGHEMv Electromagnetic (EM) system and a CGG D1344 cesium magnetometer with a Scintrex CS3 cesium sensor. 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-B3 Squirrel helicopter at a mean terrain clearance of 60 m along NE-SW (12 degrees) 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. These data were produced under contract between the State of...
The Bonnifield electromagnetic and magnetic airborne geophysical survey data were acquired in 2006 and 2007 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-B3 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 for part of the Bonnifield mining district in Interior Alaska. Aeromagnetic and electromagnetic...
