Aeromagnetic survey data collected over the Eagle Plains region in Yukon, Canada, between April 10, 2009 and September 16, 2009. The survey was flown by EON Geosciences Inc. using aircraft equipped with cesium vapour magnetometers, with a nominal terrain clearance of 250 meters and traverse lines spaced 800 meters apart. The total magnetic field data was interpolated to a 200-meter grid without removal of the International Geomagnetic Reference Field.
Use Cases
- Map subsurface geological structures based on magnetic field anomalies.
- Support mineral exploration targeting based on interpreted magnetic signatures.
- Conduct geophysical research on the Earth's crust in the Yukon region.
- Integrate with other geospatial datasets for regional geological analysis.
Strengths
- Data was collected with high-sensitivity cesium vapour magnetometers (0.005 nT).
- Flight lines were computer-analyzed and mutually levelled to minimize intersection errors.
- Survey parameters are precisely documented, including line spacing (800 m traverse, 2400 m control) and terrain clearance (250 m).
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.
