First Vertical Derivative of the Magnetic Field, Aeromagnetic Survey of the Marsh Lake Are

An aeromagnetic survey conducted by Geo Data Solutions GDS Inc. from January 12, 2018 to March 16, 2018. Data were recorded using split-beam cesium vapour magnetometers mounted on a Beechcraft King Air and a Piper Navajo aircraft. The survey used a nominal traverse line spacing of 400 m, control line spacing of 2400 m, and a nominal terrain clearance of 150 m.

Use Cases

• Map subsurface geological structures based on magnetic field variations.
• Support mineral exploration targeting based on aeromagnetic anomalies.
• Conduct geophysical research on the Marsh Lake area's crustal composition.

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 is provided by the Government of Yukon, suggesting an official source.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to a single survey area.
