Aeromagnetic Survey of the Marsh Lake Area, Yukon, 2018

Yukon's Marsh Lake area was surveyed by Geo Data Solutions GDS Inc. from January 12 to March 16, 2018. The data were collected using cesium vapour magnetometers mounted on aircraft flying at a nominal terrain clearance of 150 meters. The survey includes traverse lines 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 gradients.
• Support mineral exploration targeting based on magnetic anomalies.
• Integrate with other geophysical datasets for regional geological modeling.
• Conduct geophysical research on the magnetic properties of the Yukon's bedrock.

Strengths

• Survey conducted over a defined period from January 12 to March 16, 2018.
• Specific flight parameters are documented, including a 150-meter terrain clearance and 400-meter line spacing.
• Data collection method is described, using split-beam cesium vapour magnetometers on specific aircraft models.

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.
