Residual Total Magnetic Field Survey of the Marsh Lake Area, Yukon

An aeromagnetic survey flown from January 12 to March 16, 2018, collecting residual total magnetic field data. The survey was conducted by Geo Data Solutions GDS Inc. for the Government of Yukon using split-beam cesium vapour magnetometers mounted on aircraft.

Use Cases

• Map subsurface geological structures based on magnetic anomaly patterns.
• Support mineral exploration targeting based on magnetic signatures.
• Create regional geological maps based on aeromagnetic data.
• Calibrate or validate other geophysical models based on the survey's specifications.

Strengths

• Survey conducted with specific technical parameters: 400 m traverse line spacing, 2400 m control line spacing, and 150 m nominal terrain clearance.
• Data collection period is precisely defined from January 12, 2018 to March 16, 2018.
• Survey was conducted by a named contractor (Geo Data Solutions GDS Inc.) for a government organization.

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.
