Dawson Area Aeromagnetic Survey with 125m Terrain Clearance

Goldak Airborne Surveys conducted an aeromagnetic survey of the Dawson area from February 17 to March 21, 2014. The data were collected using split-beam cesium vapour magnetometers mounted on two Piper Navajo aircraft. Nominal traverse and control line spacings were 400 and 1400 meters, with a nominal terrain clearance of 125 meters.

Use Cases

• Map subsurface geological structures based on magnetic field variations.
• Identify potential mineral deposits based on magnetic anomaly patterns.
• Integrate magnetic data with other geophysical surveys for regional geological modeling.

Strengths

• Data collection period is precisely defined as February 17 to March 21, 2014.
• Survey parameters are specified, including 400m traverse line spacing and 125m nominal terrain clearance.
• Collection method is described, using split-beam cesium vapour magnetometers on two aircraft.

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 bias inherent to the specific survey area.
