Farewell and Middle Styx survey areas: Project report, interpretation maps, EM anomalies, stacked multi-channel profiles, and other products of the airborne geophysical surveys, parts of the McGrath, Lime Hills, and Tyonek quadrangles, south-central Alaska

This digital publication, GPR 2014-4, contains CGG's analysis and interpretation of data produced from airborne geophysical surveys published by DGGS in 2013 (GPR 2013-1) and 2014 (GPR 2014-5) for the Middle Styx and Farewell survey areas respectively. The two survey blocks Farewell and Middle Styx are referred to as the 'Farewell' survey in the project report as these blocks were flown under one contract. Elsewhere the separate block names, Farewell and Middle Styx, are typically used. CGG's frequency-domain DIGHEM V system was used for the EM data. GPR 2014-4 includes (1) CGG's project report with interpretation and detailed EM Anomalies, and (2) Multi-channel stacked profiles in pdf format. Interpretation maps and EM anomalies are provided in various formats (e.g., Geotiffs , KMZs, and others) and are listed in detail in gpr2014_004_readme (.txt and .pdf). Other supporting files include gpr2014_004_browsegraphic.pdf, farewell_middlestyx_emanomaly_readme.pdf, farewell_middlestyx_smprofiles_readme.pdf, and many legends as jpgs.
