Residual Total Magnetic Field Survey of Kluane Area, Yukon, 2010

A February 4 to March 15, 2010 helicopter-borne aeromagnetic survey of the Kluane area in Yukon, Canada. The Government of Yukon produced this map of the residual total magnetic field from data acquired by Fugro Airborne Surveys using two Astar 350B aircraft equipped with cesium vapour magnetometers.

Use Cases

• Map subsurface geological structures based on magnetic field anomalies.
• Support mineral exploration targeting based on magnetic signatures.
• Integrate with other geophysical datasets for regional geological interpretation.
• Calibrate or validate other magnetic survey instruments or methods.

Strengths

• Survey conducted with precise instrumentation: split-beam cesium vapour magnetometers with a sensitivity of 0.005 nT.
• Flight parameters are specified: nominal traverse line spacing of 400 m, control line spacing of 2400 m, and terrain clearance of 100 m.
• Flight path was recovered using post-flight differential GPS corrections and video ground imagery.

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 a single, localized survey.
