Residual Total Magnetic Field, Nisling River Area Aeromagnetic Survey, 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 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 m.

Use Cases

• Map regional geological structures based on magnetic field anomalies.
• Assess mineral exploration potential based on high-resolution magnetic data.
• Conduct geophysical research based on a large, systematically collected aeromagnetic dataset.

Strengths

• 37,999 line kilometres of high-resolution magnetic data were collected.
• Survey used high-sensitivity cesium vapour magnetometers and differential GPS for positioning.
• Traverse lines were flown at a consistent 400 m spacing with 100 m nominal terrain clearance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
