Aeromagnetic Survey of the Dawson Area, Yukon, 2014

First vertical derivative data from an aeromagnetic survey flown over the Dawson area in Yukon, Canada. The survey was conducted by Goldak Airborne Surveys between February 17 and March 21, 2014, using two Piper Navajo aircraft equipped with cesium vapour magnetometers. Nominal traverse line spacing was 400 meters with a terrain clearance of 125 meters.

Use Cases

• Map subsurface geological structures based on magnetic field variations.
• Support mineral exploration targeting based on magnetic anomaly patterns.
• Integrate with other geophysical datasets for regional geological interpretation.
• Conduct geophysical research on the magnetic properties of the Dawson area.

Strengths

• Survey conducted over a defined five-week period in 2014.
• Data collected using specific instrumentation: split-beam cesium vapour magnetometers.
• Nominal flight parameters are specified: 400 m traverse line spacing and 125 m terrain clearance.

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 and temporal bias inherent to the specific survey.
