This digital publication, GPR 2014-3, contains CGG's analysis and interpretation of data produced from airborne geophysical surveys published by DGGS in 2013 (GPR 2013-1) for the Southern Dishna River, Fox Hills, and Beaver Creek survey areas. These three survey areas are informally referred to as the Five Spot survey in places in this publication. CGG's frequency-domain DIGHEM V system was used for the EM data. GPR 2014-3 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 GPR2014-003 ReadMe (.txt and...

This digital publication, GPR 2013-1, contains data produced from airborne geophysical surveys conducted in 2012 for three separate blocks, the Southern Dishna River, Fox Hills, and Beaver Creek survey areas, in the Iditarod, Ophir, and Holy Cross quadrangles in western Alaska. The areas are in the Iditarod, Innoko, and Aniak mining districts. Aeromagnetic and electromagnetic (EM) data were acquired by helicopter for about 1029 sq miles. Fugro Airborne Survey's frequency-domain DIGHEM V system was used for the EM data. GPR 2013-1 includes (1) raw and processed linedata; (2) gridded, Google Earth, and Geotiff formats of the calculated linedata; (3) maps of the data; and (4) vector files of data contours and flight...
