Dawson Area Aeromagnetic Survey with 125m Terrain Clearance

Yukon, Canada, specifically the Dawson area (NTS 115N/15 and parts of 115N/7, 9, 10, 16, and 115O/13), was surveyed for residual total magnetic field data. Goldak Airborne Surveys collected the data using split-beam cesium vapour magnetometers mounted on two Piper Navajo aircraft between February 17 and March 21, 2014. The survey had nominal traverse and control line spacings of 400 and 1400 meters, with 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.
• Conduct regional geological interpretation based on aeromagnetic survey data.
• Integrate magnetic data with other geophysical datasets for comprehensive analysis.

Strengths

• Survey conducted with specific technical parameters: 400m traverse and 1400m control line spacings.
• Data collection occurred over a defined period from February 17 to March 21, 2014.
• Aircraft maintained a nominal terrain clearance of 125 meters.

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.
