Ladue Geophysical Survey

The digital data below was produced from airborne geophysical surveys conducted in 2010 for the Ladue survey area in the Fortymile mining district, Tanacross quadrangle, eastern Alaska. Aeromagnetic and electromagnetic (EM) data were acquired by helicopter for about 742 sq miles. Fugro Airborne Survey's frequency-domain DIGHEM V system was used for the EM data. GPR 2011-1 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 lines. A future publication will include the technical project report, interpretation map, and EM anomalies, as well as other files.
