Line, grid, and vector data, and maps for the airborne geophysical survey data of the Styx River Survey, parts of the Lime Hills and Tyonek quadrangles, southcentral Alaska

This digital publication, GPR 2008-3, contains data 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. Data are described in more detail in the 'gpr2008_003_readme.pdf' and 'Styx-Linedata.txt' files included on the DVD.
