Purpose: This electromagnetic and magnetic airborne geophysical survey data compilation is a product of the Alaska Division of Geological & Geophysical Surveys' (DGGS) Airborne Geophysical/Geological Mineral Inventory (AGGMI) program and the Alaska Strategic and Critical Minerals Assessment Capital Improvement Project. The goal of the Alaska Division of Geological & Geophysical Surveys' (DGGS) Airborne Geophysical/Geological Mineral Inventory (AGGMI) program is to enhance the understanding of Alaska's mineral resources and stimulate private-sector mineral development. The program seeks to delineate mineral zones on Alaska State lands that: (1) have major economic value; (2) can be developed in the short term to provide high-quality jobs for Alaskans; and (3) will provide economic diversification to help offset the loss of Prudhoe Bay oil revenue. Candidate lands for this program are identified on the basis of existing geologic knowledge, land ownership, and nominations from Alaska's geologic community. The AGGMI program and resulting new geologic knowledge are recognized worldwide and have encouraged millions of dollars of venture capital expenditures in the local economies of the surveyed mining districts. These venture capital expenditures have led to discovery and delineation of new mineral resources. The multi-year Strategic and Critical Minerals Assessment Capital Improvement Project (SCMA) was established to determine Alaska's geologic potential for rare-earth elements and other minerals that are essential for our modern, technology-based society. This program began in FY2012 with a data survey and compilation of existing information on rare-earth-element occurrences in Alaska, and expanded significantly in FY2013 to include additional critical minerals, re-analyses of existing samples, and obtaining new field and analytical data, including airborne geophysics. Supplemental_Information: >wran_ic_sdr_vc_nik: Geosoft format gridded data, ER Mapper format gridded data, ESRI ArcGIS shapefile, and keyhole markup language (.kml) data archive files. Note: these data are provided in both UTM Zone 6 - NAD27 and Geographic WGS84 projections. The data files were compiled from the Wrangellia, Iron Creek, Southern Delta River, Valdez Creek, and Nikolai geophysical surveys.

These exceptions did not noticeably impact data quality. Additional detail about contract specifications and operational issues can be found in the metadata of the originating surveys. Logical_Consistency_Report: These data originate from multiple similar geophysical surveys with different specifications. Reference the metadata of each originating survey for exact specifications. Completeness_Report: Helicopter and fixed wing geophysical surveys often have small data gaps that do not negatively impact the overall quality of the final products. Reference the metadata for each originating survey for specific details. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: All originating data were positioned by DGPS (Differential Global Positioning System) with an accuracy of 5 meters or better.

The diurnally corrected magnetic data were adjusted for regional variations i.e. IGRF gradient. The residual grids of all the areas may, therefore, have different base values dependent on the IGRF model used for each grid. The grids were adjusted to each other prior to the final merge. Prior to merging the gridded data for Iron Creek with the 2013 Wrangellia survey, the coplanar data were multiplied by a factor of 2, and the resistivity was recalculated with higher upper limits of apparent resistivity, which are now used in processing more recent datasets. The data were re gridded and merged with the Wrangellia resistivity grids. Oasis Montaj grid "Suture" technique with the "No De-trending" option was used to merge the grids. The process requires selecting a "master" grid or the grid that all other grids will be leveled to. The grid that was published first is usually chosen and the grid from the most recent survey was selected as the secondary grid (i.e. the grid that will be DC shifted to the master grid). Process_Date: 2013 Process_Step: Process_Description: Boundary - DGGS staff constructed a boundary of the merged grid file. The grid boundary was constructed using Geosoft Oaisis montaj grid outline and map export functions. The boundary file is available in Geosft PLY ASCII format and ESRI Shapefile format. Process_Date: 2017 Process_Step: Process_Description: Google Earth KMZ files - DGGS staff created Google Earth KMZ/KML files from the grid files data using ESRI ArcGIS software.
