Aeromagnetic Survey of the Marsh Lake Area, Yukon, 2018

First vertical derivative data from an aeromagnetic survey flown over the Marsh Lake area in Yukon, Canada. The survey was conducted by Geo Data Solutions GDS Inc. from January 12 to March 16, 2018, using split-beam cesium vapour magnetometers mounted on two aircraft. Flight lines were oriented N45°E with a nominal spacing of 400 m and a 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 datasets for geological modeling.

Strengths

• Survey conducted over a defined period from January 12 to March 16, 2018.
• Specific flight parameters are documented, including 400 m line spacing and 150 m terrain clearance.
• Data represents a processed derivative (first vertical derivative) of the magnetic field.

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.
