Eagle Plains Aeromagnetic Survey: Total Magnetic Field Map of Yukon

Yukon's Eagle Plains region is covered by this total magnetic field map derived from an aeromagnetic survey flown between April 10, 2009 and September 16, 2009. Data were acquired by EON Geosciences Inc. using cesium vapour magnetometers mounted on aircraft flying at a nominal 250-meter terrain clearance. The levelled magnetic data were interpolated to a 200-meter grid, and the International Geomagnetic Reference Field was not removed.

Use Cases

• Geological mapping based on magnetic field anomalies.
• Mineral exploration targeting based on subsurface magnetic structures.
• Regional geophysical analysis based on a 200-meter interpolated grid.
• Survey methodology research based on described aircraft and instrumentation specifications.

Strengths

• Data acquired with high-sensitivity cesium vapour magnetometers (0.005 nT).
• Survey flown with specific parameters: 800 m traverse line spacing, 2400 m control line spacing, and 250 m nominal terrain clearance.
• Flight path was recovered using post-flight differential GPS corrections and video inspection.

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 data.
• Row count is unknown, which may limit suitability assessment.
