Nisling River Aeromagnetic Survey with 37,999 Line Kilometres, Yukon 2011

Between January 25th and March 26th, 2011, Goldak Airborne Surveys collected high-resolution magnetic data for the Geological Survey of Canada. The survey comprises 37,999 line kilometres flown with 400 m traverse line spacing and 100 m nominal terrain clearance. Data were recorded digitally using cesium vapour magnetometers and differential GPS.

Use Cases

• Map subsurface geological structures based on magnetic field anomalies.
• Support mineral exploration targeting based on high-resolution magnetic data.
• Conduct geophysical research on the Nisling River area's crustal composition.
• Integrate magnetic data with other geological datasets for regional analysis.

Strengths

• High-resolution data collection over 37,999 line kilometres.
• Survey conducted with high-sensitivity equipment including three cesium vapour magnetometers.
• Specific flight parameters documented, 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 15:40:01.077791.
