EON Geosciences Inc. acquired this total magnetic field map during an aeromagnetic survey flown between April 10, 2009 and September 16, 2009. The data were recorded using cesium vapour magnetometers from aircraft flying at a nominal terrain clearance of 250 m, with traverse lines spaced 800 m apart. The Government of Yukon provides the levelled and gridded data where the International Geomagnetic Reference Field was not removed.
Use Cases
- Map subsurface geological structures based on magnetic anomaly patterns.
- Support mineral exploration targeting based on magnetic signatures of ore bodies.
- Conduct regional geophysical analysis based on high-resolution aeromagnetic data.
- Calibrate or validate other geophysical models based on the detailed magnetic field measurements.
Strengths
- Data collection used high-sensitivity magnetometers with a sensitivity of 0.005 nT.
- Flight lines were flown at a low nominal terrain clearance of 250 m for detailed resolution.
- Data were 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 (IGRF) was not removed from the magnetic field data.
- Row count is unknown, which may limit suitability assessment.
