First Vertical Derivative of Magnetic Field, Kluane Yukon Aeromagnetic Survey 2010

A 2010 helicopter-borne aeromagnetic survey over parts of Kluane, Yukon, acquired data using cesium vapour magnetometers with a sensitivity of 0.005 nT. Fugro Airborne Surveys flew two Astar 350B aircraft at a nominal terrain clearance of 100 m, with traverse lines spaced 400 m apart and oriented N30°E. The map represents the first vertical derivative of the total magnetic field, processed with differential GPS corrections.

Use Cases

• Mineral exploration targeting based on magnetic anomaly patterns.
• Geological mapping and structural interpretation of the Kluane area.
• Integrating magnetic derivative data with other geophysical or geological datasets for regional analysis.

Strengths

• Data was collected with high-sensitivity cesium vapour magnetometers (0.005 nT).
• Flight parameters are precisely documented, including 100 m terrain clearance and 400 m traverse line spacing.
• Post-flight processing included differential GPS corrections and video ground image inspection for flight path recovery.

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 and temporal bias inherent to the specific 2010 survey.
