Yukon Aeromagnetic Survey Data from Fugro Airborne Surveys, 2003

Aeromagnetic Total Field, Yukon Territory, NTS 106L/NE-NW is a geospatial dataset compiled from an aeromagnetic survey conducted by Fugro Airborne Surveys in 2003. Survey operations used a Cessna Caravan aircraft with a cesium vapour magnetometer, flown at a nominal terrain clearance of 200 m. The levelled total field values were interpolated to a 200 m grid, and the International Geomagnetic Reference Field has not been removed.

Use Cases

• Map subsurface geological structures based on magnetic total field data.
• Analyze magnetic anomalies for mineral exploration targeting.
• Integrate with other geophysical datasets for regional geological studies.
• Validate or calibrate airborne survey methodologies.
• Study local geomagnetic field variations without the International Geomagnetic Reference Field removed.

Strengths

• Survey conducted with a 0.005 nT sensitivity magnetometer, indicating high-precision instrumentation.
• Flight path recovered using differential GPS and a video camera, suggesting accurate spatial positioning.
• Data levelled and interpolated to a consistent 200 m grid.
• Specific survey period from March 7 to May 1, 2003, and nominal line spacings of 800 m and 2.4 km are documented.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The International Geomagnetic Reference Field has not been removed, which may complicate direct comparison with other magnetic datasets.
