Nisling River Aeromagnetic Survey: First Vertical Derivative, Yukon 2011

A high-sensitivity aeromagnetic survey covering the Nisling River area in Yukon, Canada. The survey was conducted by Goldak Airborne Surveys for the Geological Survey of Canada between January 25 and March 26, 2011, collecting 37,999 line kilometres of data. Traverse lines were flown at a 400 m spacing with a nominal terrain clearance of 100 meters.

Use Cases

• Model subsurface geological structures based on high-resolution magnetic field data.
• Assess mineral exploration potential by analyzing magnetic anomalies in the survey area.
• Calibrate geophysical instruments and methods using the detailed flight and equipment specifications.
• Conduct regional geological mapping by integrating the processed magnetic derivative with other geospatial data.

Strengths

• High-resolution data collection over 37,999 line kilometres.
• Detailed survey methodology documented, including flight spacing of 400 m and terrain clearance of 100 m.
• Data processed from multiple calibrated instruments, including three cesium vapour magnetometers.

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 2011 survey period.
