Aeromagnetic Survey of the Nisling River Area, Yukon, 2011

37,999 line kilometres of high-resolution magnetic data were collected over a Yukon survey block in 2011. Goldak Airborne Surveys conducted this high-sensitivity survey for the Geological Survey of Canada using cesium vapour magnetometers and differential GPS. Traverse lines were flown at 400 m spacing with a nominal terrain clearance of 100 meters.

Use Cases

• Map subsurface geological structures based on magnetic field anomalies.
• Identify potential mineral deposits based on magnetic signatures.
• Create 3D geological models based on high-resolution aeromagnetic data.
• Calibrate regional geophysical models based on detailed survey data.

Strengths

• High-resolution data collection over 37,999 line kilometres.
• Survey conducted with three cesium vapour magnetometers for high sensitivity.
• 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.
• Data freshness should be verified; the last metadata update is 2026-05-20.
