Nisling River Aeromagnetic Survey: Residual Total Magnetic Field, Yukon 2011

Goldak Airborne Surveys collected 37,999 line kilometres of high-resolution magnetic data for the Geological Survey of Canada between January 25th and March 26th, 2011. 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 meters.

Use Cases

• Map regional geological structures based on magnetic anomaly patterns.
• Support mineral exploration targeting based on magnetic signatures.
• Integrate with other geophysical datasets for subsurface modeling.
• Calibrate and validate airborne magnetic survey methodologies.

Strengths

• High-resolution data collection over 37,999 line kilometres.
• Survey conducted with high-sensitivity cesium vapour magnetometers and differential GPS.
• Specific flight parameters are documented, including 400 m line spacing and 100 m terrain clearance.

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 the specific survey area and period.
