Aeromagnetic Survey of the Marsh Lake Area, Yukon, 2018

Aeromagnetic survey data collected over the Marsh Lake area in Yukon, Canada, from January 12 to March 16, 2018. The survey was conducted by Geo Data Solutions GDS Inc. using split-beam cesium vapour magnetometers mounted on aircraft. Traverse lines were flown at a nominal 150-meter terrain clearance with 400-meter spacing.

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.

Strengths

• Survey conducted over a defined two-month period in early 2018.
• Specific flight parameters are documented, including 150-meter nominal terrain clearance and 400-meter 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.
