Nisling River Aeromagnetic Survey First Vertical Derivative, Yukon 2011

Goldak Airborne Surveys collected 37,999 line kilometres of high-resolution magnetic data for the Geological Survey of Canada in early 2011. The survey covered the Nisling River area in Yukon, with traverse lines flown at 400 m spacing and a nominal terrain clearance of 100 m. Data were recorded digitally using cesium vapour magnetometers and differential GPS.

Use Cases

• Map subsurface geological structures based on magnetic field gradients.
• Support mineral exploration targeting based on magnetic anomaly patterns.
• Integrate with other geophysical datasets for regional geological interpretation.
• Calibrate airborne survey methodologies using the detailed flight and equipment specifications.

Strengths

• Survey collected 37,999 line kilometres of data, indicating substantial spatial coverage.
• High sensitivity equipment included three cesium vapour magnetometers and differential GPS.
• Flight parameters are specified, 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/temporal bias inherent to open_canada.
