Data were acquired by helicopter between August 20th and August 22nd, 2016, by Precision GeoSurveys Inc. The survey helicopter was equipped with a Scintrex cesium vapor CS-3 magnetometer, spectrometer, data acquisition system, magnetic compensation system, pilot guidance unit (PGU), and GPS navigation system. A Garmin VIRB XE video camera integrated with a GPS antenna was used to record the flight path video. In addition, two GEM GSM-19T magnetometer base stations with integrated GPS time synchronization were used to record diurnal magnetic variations. The survey area consists of four contiguous blocks covering an irregular area of 42.5 km by 19.1 km with 173 survey lines and 16 tie lines. The four blocks are centered 130 km northwest of Yakutat, Alaska, and cover a total of 520.8 square km. A total of 846.2 line-km were collected. The data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/29742.\r\n This airborne magnetic survey was performed to evaluate and promote State of Alaska, Mental Health Trust owned lands in the Icy Cape area for accumulations of concentrated heavy mineral sands.\r\n >ascii_data: ASCII format line data, other ASCII data\t\r\n>databases_geosoft: Geosoft format database of line data, other Geosoft format databases\t\r\n>documents: Project and field reports, survey background information, gridded data explanations, other supporting documentation\t\r\n>grids_ermapper: Geographically registered gridded data, ER Mapper ERS format\t\r\n>grids_geosoft: Geosoft-format binary grids, these grids can be viewed in ESRI ArcMap using a free plugin from Geosoft or using the free viewer available from Geosoft\t\r\n>images_registered: GeoTiff format images of all gridded data\t\r\n>kmz: Keyhole markup language (kml) kmz archive files of project data.

For additional detail about survey parameters, see the accompanying project report available in the documents directory of this data distribution package.\r\n \r\n Data originate from one company using the same contract specifications for all data. The originating coordinate system was retained for all publication products.\r\n This data set includes files that contain processed aeromagnetic measurements, electromagnetic measurements, altimetry measurements, and locational data for the entire survey area.\r\n \r\n \r\n Station coordinates were positioned using a real-time or post-processed corrected differential GPS.\r\n \r\n \r\n Not applicable\r\n \r\n \r\n \r\n \r\n Data collection, processing, and delivery - The airborne geophysical data were acquired under contract with Precision GeoSurveys Inc. Airborne geophysical data for the area were acquired and processed by Precision GeoSurveys Inc. The contractor's project report and other supporting documents are in the \"documents\" digital data package. They provide detailed documentation of the system specifications, data collection, processing, and delivery.\r\n 2016\r\n \r\n \r\n RGB GeoTiff creation - RGB GeoTIFF raster files of gridded data were exported using Geosoft v9 by loading each Geosoft grid onto a map and using the map export tool.\r\n 2020\r\n \r\n \r\n ER Mapper grid creation - Data value ER Mapper ers format grids were created from the delivered Geosoft format grids using Geosoft Oasis montaj v9. The grid copy/convert tool was used.\r\n 2020\r\n \r\n \r\n Merged Boundary Polygon - A merged and dissolved boundary polygon was created in ArcMap from the four polygons of each data block.\r\n 2020\r\n \r\n \r\n Data cataloged for archival and publication - All files were renamed and placed in a standardized set of folders according to the DGGS Geophysics Data Management Manual. Where applicable and as needed data were converted to newer file formats, and new files were created. Supporting documentation, including but not limited to readme text files, maps, figures, survey overview report, missing data type explanations, and metadata were created.\r\n 2020\r\n \r\n \r\n \r\n \r\n raster\r\n \r\n \r\n \r\n \r\n \r\n Universal Transverse Mercator\r\n \r\n 7\r\n \r\n 0.999600\r\n -141\r\n 0\r\n 500000.000000\r\n 0\r\n \r\n \r\n \r\n \r\n coordinate pair\r\n \r\n .00000001\r\n .00000001\r\n \r\n Meters\r\n \r\n \r\n \r\n WGS84\r\n WGS 84\r\n 6378137\r\n 298.257223563000025\r\n \r\n \r\n \r\n \r\n \r\n \r\n ascii_data\r\n ASCII format line data, other ASCII data\r\n Precision GeoSurveys Inc.\r\n ascii_data\r\n \r\n \r\n \r\n \r\n databases_geosoft\r\n Geosoft format database of line data, other Geosoft format databases\r\n Precision GeoSurveys Inc.\r\n databases_geosoft\r\n \r\n \r\n \r\n \r\n documents\r\n Project and field reports, survey background information, gridded data explanations, other supporting documentation\r\n Precision GeoSurveys Inc. and Alaska Division of Geological & Geophysical Surveys (DGGS)\r\n documents\r\n \r\n \r\n \r\n \r\n grids_ermapper\r\n Geographically registered gridded data, ER Mapper ERS format\r\n Precision GeoSurveys Inc. and Alaska Division of Geological & Geophysical Surveys (DGGS)\r\n grids_ermapper\r\n \r\n \r\n \r\n \r\n grids_geosoft\r\n Geosoft-format binary grids, these grids can be viewed in ESRI ArcMap using a free plugin from Geosoft or using the free viewer available from Geosoft\r\n Precision GeoSurveys Inc. and Alaska Division of Geological & Geophysical Surveys (DGGS)\r\n grids_geosoft\r\n \r\n \r\n \r\n \r\n images_registered\r\n GeoTiff format images of all gridded data\r\n Alaska Division of Geological & Geophysical Surveys (DGGS)\r\n images_registered\r\n \r\n \r\n \r\n \r\n kmz\r\n Keyhole markup language (kml) kmz archive files of project data.
