Aeromagnetic Survey of Nisling River Area, Yukon, 2011

Goldak Airborne Surveys collected 37,999 line kilometres of high-resolution magnetic data for the Geological Survey of Canada between January 25th and March 26th, 2011. The survey covered parts of NTS 115 H/14 and 115 H/15 in Yukon, using cesium vapour magnetometers and differential GPS. Traverse lines were flown at a 400 m spacing with a nominal terrain clearance of 100 meters.

Use Cases

• Map subsurface geological structures based on processed magnetic field data.
• Calibrate geophysical models using the detailed flight path and sensor specifications.
• Assess mineral exploration potential in the Yukon region based on magnetic anomalies.

Strengths

• 37,999 line kilometres of high-resolution magnetic data provide substantial spatial coverage.
• Survey specifications are detailed, including 400 m line spacing, 2400 m control line separation, and 100 m nominal terrain clearance.
• Data was collected using high-sensitivity equipment including three cesium vapour magnetometers and differential GPS.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data files are in PDF, ZIP, and HTML formats, which may require conversion for direct geospatial analysis.
• Row count is unknown, which may limit suitability assessment.
