Title

Aniak electromagnetic and magnetic airborne geophysical survey data compilation

Abstract

The Aniak electromagnetic and magnetic airborne geophysical survey is located in western Alaska in the Iditarod and Aniak mining districts, about 450 kilometers west of Anchorage. Frequency domain electromagnetic and magnetic data were collected with the DIGHEMV system from April to May 2000. A total of 9186.7 line kilometers were collected covering 3253.1 square kilometers. Data were collected 30 m above the ground surface from a helicopter towed sensor platform ('bird') on a 30 m long line. The survey was conducted by Fugro Airborne Surveys and Stevens Exploration Management Corp. and administered by the Alaska Geological & Geophysical Surveys (DGGS). The data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/30221.
