Residual Total Magnetic Field from Aeromagnetic Survey of Nisling River Area, Yukon

Between January 25th and March 26th, 2011, Goldak Airborne Surveys collected 37,999 line kilometres of high-resolution magnetic data for the Geological Survey of Canada. The survey covered the Nisling River area (NTS 115 G/15 and part of 115 G/14) in Yukon, using cesium vapour magnetometers and differential GPS. Traverse lines were flown at a 400 m spacing with a nominal terrain clearance of 100 meters.

Use Cases

• Map subsurface geological structures based on the high-resolution magnetic field data.
• Identify potential mineral deposits based on magnetic anomalies in the survey area.
• Integrate magnetic data with other geophysical surveys for regional geological interpretation.
• Calibrate and validate ground-based magnetic survey equipment using the airborne reference data.

Strengths

• High-resolution data collection covering 37,999 line kilometres.
• Survey conducted with high-sensitivity equipment including three cesium vapour magnetometers.
• Precise flight parameters: 400 m line spacing, 100 m nominal terrain clearance.

Limitations

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