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

January 25th to March 26th, 2011, a high sensitivity aeromagnetic survey collected 37,999 line kilometres of magnetic data over the Nisling River Area in Yukon. The survey was conducted by Goldak Airborne Surveys for the Geological Survey of Canada using cesium vapour magnetometers and differential GPS. Traverse lines were flown at 400 m spacing with a nominal terrain clearance of 100 meters.

Use Cases

• Map regional geological structures based on the high-resolution magnetic field data.
• Assess mineral exploration potential by identifying magnetic anomalies from the processed survey.
• Model subsurface geology using the detailed magnetic field measurements collected at 100 m terrain clearance.

Strengths

• 37,999 line kilometres of high-resolution magnetic data provide substantial spatial coverage.
• Survey specifications include precise flight parameters: 400 m line spacing, 2400 m control line separation, and 100 m nominal terrain clearance.
• Data collection utilized high-sensitivity equipment including three cesium vapour magnetometers and differential GPS.

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 survey conducted in early 2011.
