Aeromagnetic Survey of the Marsh Lake Area, Yukon, 2018

Aeromagnetic survey data from the Marsh Lake area in Yukon, Canada, collected between January 12 and March 16, 2018. The survey was conducted by Geo Data Solutions GDS Inc. using split-beam cesium vapour magnetometers mounted on aircraft. Data includes the first vertical derivative of the magnetic field, with traverse lines spaced 400 m apart and flown at 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 high-resolution aeromagnetic data.
• Integrating magnetic data with other geospatial layers for resource assessment.

Strengths

• Data collection period is precisely defined as January 12 to March 16, 2018.
• Survey parameters are specified, including 400 m traverse line spacing and 150 m nominal terrain clearance.
• Specific instrumentation is described: split-beam cesium vapour magnetometers mounted on a Beechcraft King Air and a Piper Navajo.

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 a single survey area and period.
