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

Yukon's Kluane area is covered by a map of the first vertical derivative of the total magnetic field. The data were acquired via helicopter-borne survey between February 4 and March 15, 2010, using cesium vapour magnetometers with 0.005 nT sensitivity. The Government of Yukon published this dataset, which was flown with 400 m traverse line spacing at a nominal 100 m terrain clearance.

Use Cases

• Geological mapping based on magnetic field derivative data.
• Mineral exploration targeting based on aeromagnetic anomalies.
• Geophysical research on subsurface structures in the Kluane area.
• Validating or integrating regional geophysical models based on high-resolution survey parameters.

Strengths

• Survey conducted with high-sensitivity (0.005 nT) cesium vapour magnetometers.
• Flight path was recovered using post-flight differential GPS corrections and video ground images.
• Specific nominal flight parameters: 400 m traverse line spacing, 2400 m control line spacing, and 100 m terrain clearance.
• Survey was flown on a pre-determined flight surface to minimize magnetic value differences at line intersections.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset scale are unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to a single 2010 survey.
