Dawson Area Aeromagnetic Survey: Residual Total Magnetic Field, 2014

Aeromagnetic survey data collected over the Dawson area in Yukon, Canada, covering NTS map sheets 116B/4, 5, 116C/1, 2, 7, 8. Goldak Airborne Surveys conducted the survey from February 17 to March 21, 2014, using two aircraft equipped with split-beam cesium vapour magnetometers. The data were collected with nominal traverse and control line spacings of 400 and 1400 meters and a nominal terrain clearance of 125 meters.

Use Cases

• Map subsurface geological structures based on magnetic field anomalies.
• Support mineral exploration targeting based on magnetic signatures.
• Integrate with other geophysical datasets for regional geological modeling.

Strengths

• Survey conducted over a defined period from February 17 to March 21, 2014.
• Specific technical parameters are provided, including 400 m traverse line spacing and 125 m terrain clearance.
• Data is provided by the Government of Yukon, a governmental source.

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/temporal bias inherent to the specific survey area and period.
