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

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

• Geological mapping based on magnetic anomaly patterns.
• Mineral exploration targeting based on subsurface magnetic structures.
• Regional geophysical analysis based on the 400 m traverse line spacing.
• Integrating magnetic data with other geospatial datasets for the Marsh Lake area.

Strengths

• Survey conducted over a defined period from January 12 to March 16, 2018.
• Specific flight parameters: 400 m traverse line spacing, 2400 m control 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.
