Wolf Lake Aeromagnetic Survey: First Vertical Derivative of the Magnetic Field, Yukon

Novatem Inc. conducted an aeromagnetic survey from February 23 to April 2, 2019, using cesium vapour magnetometers mounted on two Piper Navajo aircraft. The survey covers the Wolf Lake area in Yukon, Canada, with traverse lines spaced 400 meters apart and flown at a nominal terrain clearance of 150 meters. This dataset provides the first vertical derivative of the magnetic field, a processed geophysical measurement.

Use Cases

• Map subsurface geological structures based on magnetic field variations.
• Support mineral exploration targeting by identifying magnetic anomalies.
• Integrate with other geospatial data for regional geological modeling.
• Calibrate or validate geophysical processing algorithms using the specified survey parameters.

Strengths

• Survey conducted over a defined period from February 23 to April 2, 2019.
• Specific technical parameters are provided, including 400 m line spacing and 150 m terrain clearance.
• Data is provided by a government organization (Government of Yukon) under an open license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific survey area in Yukon.
