First Vertical Derivative of the Magnetic Field, Wolf Lake Area Yukon

Aeromagnetic survey data collected over the south half of NTS 105F in the Wolf Lake area of Yukon. The survey was conducted by Novatem Inc. from February 23 to April 2, 2019 using cesium vapour magnetometers mounted on two Piper Navajo aircraft. Traverse lines were flown at a nominal 150-meter terrain clearance with 400-meter spacing oriented N45°E.

Use Cases

• Map subsurface geological structures based on processed magnetic field data.
• Support mineral exploration targeting based on magnetic anomaly patterns.
• Integrate with other geophysical datasets for regional geological modeling.
• Calibrate or validate airborne geophysical survey methodologies.

Strengths

• Survey conducted with specific instrumentation: split-beam cesium vapour magnetometers.
• Precise flight parameters: nominal 150 m terrain clearance and 400 m line spacing.
• Clear temporal coverage from February 23 to April 2, 2019.

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 bias inherent to the specific survey area.
