Wolf Lake Aeromagnetic Survey: Residual Total Magnetic Field Data, Yukon 2019

Residual Total Magnetic Field data from an aeromagnetic survey of the Wolf Lake area in Yukon, part of NTS 105G (south half). The survey was conducted by Novatem Inc. from February 23, 2019 to April 2, 2019 using split-beam cesium vapour magnetometers mounted on two Piper Navajo aircraft. Traverse lines were flown at a nominal 150 m terrain clearance with 400 m spacing oriented N45°E and orthogonal control lines at 2400 m spacing.

Use Cases

• Geological mapping based on magnetic anomaly patterns.
• Mineral exploration targeting based on subsurface magnetic structures.
• Geophysical research and modeling of the Earth's magnetic field in a specific region.
• Integrating magnetic data with other geospatial datasets for regional analysis.

Strengths

• Survey conducted with specific technical parameters: 400 m traverse line spacing and 2400 m control line spacing.
• Aircraft flew at a nominal terrain clearance of 150 m, providing high-resolution data.
• Clear temporal coverage from February 23, 2019 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 in Yukon.
