Eagle Plains Aeromagnetic Survey: Total Magnetic Field Map of Yukon, 2009

A geospatial map of the total magnetic field derived from an aeromagnetic survey flown over the Eagle Plains area in Yukon, Canada. The data were acquired between April 10, 2009 and September 16, 2009 using cesium vapour magnetometers mounted on aircraft flying at a nominal terrain clearance of 250 meters. The Government of Yukon produced this dataset, which consists of levelled and interpolated magnetic measurements where the International Geomagnetic Reference Field was not removed.

Use Cases

• Mineral exploration targeting based on magnetic anomaly patterns.
• Geological mapping and structural interpretation of the subsurface.
• Research on regional magnetic field characteristics in northern terrains.
• Integration with other geophysical datasets for multi-disciplinary earth science studies.

Strengths

• Data acquired with high-sensitivity cesium vapour magnetometers (0.005 nT).
• Survey flown with specific flight parameters: 800 m traverse line spacing, 2400 m control line spacing, and 250 m nominal terrain clearance.
• Data were levelled and interpolated to a 200 m grid for consistency.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The International Geomagnetic Reference Field (IGRF) was not removed from the magnetic field values.
• Row count is unknown, which may limit suitability assessment.
