Residual Total Magnetic Field, Aeromagnetic Survey of the Marsh Lake Area, Yukon, Part of NTS 105D/South

This aeromagnetic survey was carried out by Geo Data Solutions GDS Inc. from January 12, 2018 to March 16, 2018. The data were recorded using split-beam cesium vapour magnetometers mounted in the tail booms of a Beechcraft King Air and a Piper Navajo. The nominal traverse and control line spacings were 400 m and 2400 m, and the aircraft flew at a nominal terrain clearance of 150 m. Travers lines were oriented N45°E with orthogonal control lines.
