Yukon Aeromagnetic Survey Map, First Vertical Derivative, 2003

March 7 to May 1, 2003 aeromagnetic survey data collected by Fugro Airborne Surveys over Yukon Territory NTS 106F/NE-NW. The survey used a Cessna Caravan aircraft equipped with a 0.005 nT sensitivity cesium vapour magnetometer, flown at a nominal terrain clearance of 200 m with 800 m traverse line spacing. 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 field gradients.
• Identify potential mineral deposits based on magnetic anomaly patterns.
• Integrate magnetic data with other geophysical surveys for regional geological modeling.
• Validate and calibrate aeromagnetic survey methodologies based on detailed flight and instrumentation parameters.

Strengths

• Survey conducted with a high-sensitivity 0.005 nT magnetometer.
• Flight path recovered using differential GPS and video camera, suggesting precise spatial control.
• Data levelled and interpolated to a consistent 200 m grid.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The International Geomagnetic Reference Field has not been removed, which may affect interpretation.
• Row count and data size are unknown, which may limit suitability assessment.
