Nisling River Aeromagnetic Survey First Vertical Derivative, 2011

Yukon's Nisling River area was surveyed by Goldak Airborne Surveys for the Geological Survey of Canada in early 2011. The survey collected 37,999 line kilometres of high-resolution magnetic data via 82 flights, with traverse lines spaced 400 meters apart. It used cesium vapour magnetometers and differential GPS for precise positioning.

Use Cases

• Map subsurface geological structures based on processed magnetic field gradients.
• Identify potential mineral deposits based on magnetic anomaly patterns.
• Integrate magnetic data with other geological datasets for regional geological modeling.
• Calibrate geophysical instruments and methods using the detailed flight and sensor specifications.

Strengths

• Survey collected 37,999 line kilometres of high-resolution data.
• Data acquisition used three cesium vapour magnetometers and differential GPS for high sensitivity and precision.
• Flight parameters are specified, including a 400-meter line spacing and a nominal 100-meter 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/source bias inherent to open_canada.
