Styx River Geophysical Survey

The digital data below was produced from airborne geophysical surveys conducted in 2007 and 2008 for the Styx River Survey area, southcentral Alaska. Aeromagnetic and electromagnetic data were acquired for about 715 sq miles. Data provided in GPR 2008-3 include (1) raw and processed linedata in Geosoft ASCII XYZ files, (2) gridded files of magnetic data, a calculated vertical magnetic gradient (first vertical derivative), apparent resistivity data, and a digital elevation model, (3) flight lines in vector format, and maps of the data in PDF format. A future publication will include the technical project report, interpretation map, and EM anomalies, as well as other files.
