First Vertical Derivative of the Magnetic Field, Marsh Lake Area Yukon 2018

Geo Data Solutions GDS Inc. conducted an aeromagnetic survey of the Marsh Lake area in Yukon, Canada, from January 12 to March 16, 2018. Data were collected using split-beam cesium vapour magnetometers mounted on a Beechcraft King Air and a Piper Navajo aircraft. The survey flew traverse lines oriented N45°E with a nominal spacing of 400 m and a terrain clearance of 150 m.

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.
• Calibrate or validate airborne magnetic survey methodologies.

Strengths

• Survey conducted over a defined period from January 12 to March 16, 2018.
• Specific flight parameters are documented, including 400 m traverse line spacing and 150 m terrain clearance.
• Data 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/source bias inherent to open_canada.
