Marsh Lake Aeromagnetic Survey Data from Yukon, 2018

An aeromagnetic survey of the Marsh Lake area in Yukon, Canada, was conducted by Geo Data Solutions GDS Inc. from January 12 to March 16, 2018. The data were collected using cesium vapour magnetometers mounted on a Beechcraft King Air and a Piper Navajo aircraft flying at a nominal terrain clearance of 150 meters. Traverse lines were spaced 400 meters apart and oriented N45°E, with orthogonal control lines spaced 2400 meters apart.

Use Cases

• Map subsurface geological structures based on magnetic field variations.
• Support mineral exploration targeting by identifying magnetic anomalies.
• Calibrate regional geological models using high-resolution aeromagnetic data.
• Analyze flight path and survey methodology for geophysical data collection standards.

Strengths

• Survey conducted over a defined two-month period from January 12 to March 16, 2018.
• Specific flight parameters are documented, including 150 m terrain clearance and 400 m line spacing.
• Data collection methodology is described, specifying the use of 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 and temporal bias inherent to the specific survey area and period.
