Residual Total Magnetic Field Survey of the Marsh Lake Area, Yukon

Aeromagnetic data collected from January 12 to March 16, 2018 by Geo Data Solutions GDS Inc. using cesium vapour magnetometers mounted on a Beechcraft King Air and a Piper Navajo. The survey flew traverse lines spaced 400 m apart at a nominal terrain clearance of 150 m over the Marsh Lake area. The data likely contains measurements of the Earth's magnetic field for geological analysis.

Use Cases

• Map subsurface geological structures based on magnetic field anomalies.
• Support mineral exploration targeting based on inferred rock types.
• Conduct regional geological interpretation based on aeromagnetic survey patterns.
• Calibrate ground-based geophysical measurements with airborne data.

Strengths

• Survey conducted over a defined period from January 12 to March 16, 2018.
• Specific flight parameters are documented, including a 150 m nominal terrain clearance and 400 m traverse line spacing.
• Data was collected using specialized split-beam cesium vapour magnetometers.

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.
