Eagle Plains Aeromagnetic Survey: Total Magnetic Field Map of Yukon

Aeromagnetic data was collected between April and September 2009 using cesium vapour magnetometers mounted on two aircraft. The survey covered the Eagle Plains area in Yukon, Canada, with traverse lines spaced 800 meters apart and flown at a nominal terrain clearance of 250 meters. The Government of Yukon produced this map, where the raw magnetic data was levelled and interpolated to a 200-meter grid without removing the International Geomagnetic Reference Field.

Use Cases

• Geological mapping based on magnetic anomalies to identify subsurface rock structures.
• Mineral exploration targeting based on the high-resolution total magnetic field data.
• Geophysical research based on the unmodified magnetic field values, which include the International Geomagnetic Reference Field.

Strengths

• Data was collected using high-sensitivity cesium vapour magnetometers with a sensitivity of 0.005 nT.
• Flight lines were precisely controlled with a nominal 250 m terrain clearance and 800 m traverse spacing.
• The dataset has been 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 was not removed from the magnetic field values, which may complicate some analyses.
