Residual Total Magnetic Field from 2010 Kluane Area Aeromagnetic Survey, Yukon

A geospatial map of the residual total magnetic field derived from a helicopter-borne aeromagnetic survey. The survey was conducted by Fugro Airborne Surveys between February 4 and March 15, 2010, in parts of Kluane area, Yukon. Data were recorded using cesium vapour magnetometers with a sensitivity of 0.005 nT, flown at a nominal terrain clearance of 100 meters.

Use Cases

• Geological mapping based on magnetic anomaly patterns.
• Mineral exploration targeting based on subsurface magnetic structures.
• Integrating magnetic data with other geophysical surveys for regional analysis.
• Modeling bedrock geology based on the high-resolution aeromagnetic measurements.

Strengths

• Survey conducted with precise instrumentation, including split-beam cesium vapour magnetometers with a sensitivity of 0.005 nT.
• Flight parameters are documented, including a nominal terrain clearance of 100 m and traverse line spacing of 400 m.
• Flight path was recovered using post-flight differential GPS corrections and video ground imagery for accuracy.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness should be verified; the last metadata update is 2026-05-20.
• Row count and dataset scale are unknown, which may limit suitability assessment.
