Residual Total Magnetic Field Survey of Kluane Area, Yukon

A helicopter-borne aeromagnetic survey flown at a nominal terrain clearance of 100 meters provides detailed magnetic field data. Fugro Airborne Surveys conducted the work between February 4 and March 15, 2010, using cesium vapour magnetometers with a sensitivity of 0.005 nT. The Government of Yukon released the derived map of the residual total magnetic field.

Use Cases

• Map subsurface geological structures based on magnetic field anomalies.
• Support mineral exploration targeting based on magnetic signatures.
• Integrate magnetic data with other geophysical surveys for regional geological interpretation.
• Calibrate or validate airborne magnetic survey methodologies and equipment.

Strengths

• Data was collected with high-sensitivity cesium vapour magnetometers (0.005 nT).
• Survey design included a dense 400 m traverse line spacing for detailed coverage.
• 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.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific survey area.
