First Vertical Derivative of the Magnetic Field, Eagle Plains Yukon 2009

A geospatial map of the first vertical derivative of the magnetic field derived from an aeromagnetic survey flown over the Eagle Plains region in Yukon, Canada. The data were acquired by EON Geosciences Inc. between April 10, 2009 and September 16, 2009 using cesium vapour magnetometers mounted on aircraft. The processed data were interpolated to a 200 m grid, and the International Geomagnetic Reference Field was not removed.

Use Cases

• Map subsurface geological structures based on magnetic field gradients.
• Support mineral exploration targeting based on magnetic anomalies.
• Integrate with other geophysical datasets for regional geological modeling.
• Assess the magnetic signature of the terrain for environmental or engineering studies.

Strengths

• Data were collected with high-sensitivity cesium vapour magnetometers (0.005 nT).
• Flight lines were flown at a nominal terrain clearance of 250 m with specific 800 m traverse and 2400 m control line spacings.
• The flight path was recovered using post-flight differential GPS corrections and video ground images.

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 was not removed from the total magnetic field.
