Aeromagnetic Survey Data for Yukon and Northwest Territories, 2003

Goldak Airborne Surveys conducted an aeromagnetic survey from July 18 to September 2, 2003 using two Piper Navajo aircraft. The survey used 0.005 nT sensitivity magnetometers with a nominal traverse line spacing of 800 m and control lines at 2.4 km spacing at a nominal terrain clearance of 200 m. The levelled total field values were interpolated to a 200 m grid, and the International Geomagnetic Reference Field has not been removed.

Use Cases

• Map subsurface geological structures based on magnetic total field data.
• Analyze magnetic anomalies for mineral exploration potential.
• Integrate magnetic data with other geophysical datasets for regional geological studies.
• Validate or calibrate other magnetic survey methods based on the described instrumentation and methodology.

Strengths

• Survey conducted with 0.005 nT sensitivity split-beam cesium vapour magnetometers.
• Flight path recovered using post flight differential GPS combined with a vertically mounted video camera.
• Data levelled and interpolated to a 200 m grid.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The International Geomagnetic Reference Field has not been removed from the magnetic total field.
• Row count is unknown, which may limit suitability assessment.
