Description
White Mountains airborne magnetic and radiometric geophysical survey, Geophysical Report 2021-3 v. 2, covers parts of Livengood, Circle, and Fairbanks quadrangles 25 kilometers km north of Fairbanks, Alaska. Magnetic and radiometric data were collected with a fixed-wing aircraft from June 30 to August 22, 2021, by MPX Geophysics Ltd. A total of 36,933 line kilometers were collected covering 13,423 square km. The magnetometer was mounted to a rear-facing fixed boom called 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. We updated this dataset in 2025 to refine processing, removing artifacts and excess noise present in the final products provided by the original contractor. The raw data were reprocessed by Baigent Geosciences. The International Geomagnetic Reference Field correction was recalculated accounting for aircraft height and the data were relevelled using Baigent Geosciences software. A complete and detailed report on the reprocessing steps undertaken is included in the publication documents. The result of the reprocessing is that leveling artifacts have been removed and the data now display finer features, including well-defined lineaments and other anomalies which were not present in the original contractor grids. The data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/31693.
