Aeromagnetic Survey of the Nisling River Area, Yukon, 2011

Goldak Airborne Surveys conducted a high-sensitivity aeromagnetic survey 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 over the Nisling River area (NTS 115 J/2 and part of 115 J/3). Traverse lines were flown at a 400 m spacing with control lines at 2400 m separation and a nominal terrain clearance of 100 m.

Use Cases

• Map subsurface geological structures based on processed magnetic field data.
• Identify potential mineral deposits based on magnetic anomalies.
• Integrate magnetic data with other geophysical surveys for regional geological modeling.
• Calibrate geophysical instruments and methods using the described survey parameters and equipment.

Strengths

• Survey collected 37,999 line kilometres of high-resolution magnetic data.
• Data was collected using three cesium vapour magnetometers and differential GPS for precise positioning.
• Survey specifications are detailed, including a 400 m line spacing and 100 m nominal terrain clearance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness should be verified despite the future 'last updated' date of 2026-05-20.
