Aeromagnetic Survey of Nisling River Area, Yukon, 2011

The Nisling River area in Yukon, Canada, was surveyed by Goldak Airborne Surveys for the Geological Survey of Canada between January 25 and March 26, 2011. The survey collected 37,999 line kilometres of high-resolution magnetic data using cesium vapour magnetometers, with traverse lines flown at 400 m spacing and a nominal terrain clearance of 100 m. Data were recorded digitally in GEDAS binary format and processed for the first vertical derivative of the magnetic field.

Use Cases

• Map subsurface geological structures based on the high-resolution magnetic data.
• Support mineral exploration targeting based on magnetic anomaly patterns.
• Integrate with other geophysical datasets for regional geological interpretation based on the survey's spatial coverage.

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 employed 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 bias inherent to the specific survey block in Yukon.
