Residual Total Magnetic Field from Kluane Area Aeromagnetic Survey, Yukon

Fugro Airborne Surveys collected this map of the residual total magnetic field during a helicopter-borne survey flown between February 4 and March 15, 2010. The data were recorded using cesium vapour magnetometers with a sensitivity of 0.005 nT, mounted on two Astar 350B aircraft flying at a nominal terrain clearance of 100 m. The Government of Yukon provides this dataset under an open license.

Use Cases

• Map subsurface geological structures based on magnetic field anomalies.
• Support mineral exploration targeting based on magnetic signatures.
• Calibrate regional magnetic models using high-resolution, low-altitude survey data.
• Assess survey methodology effectiveness based on the described flight path recovery and intersection correction techniques.

Strengths

• Data collected with high-sensitivity magnetometers (0.005 nT).
• Survey flown at low nominal terrain clearance of 100 m for high-resolution data.
• Flight path was recovered using post-flight differential GPS corrections and video inspection.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness should be verified; last metadata update was 2026-05-20.
