Description
An aeromagnetic survey was flown between April 10, 2009 and September 16, 2009 over Yukon's Eagle Plains region. The data were recorded using split-beam cesium vapour magnetometers with a sensitivity of 0.005 nT, flown at a nominal terrain clearance of 250 m. The Government of Yukon provides this map of the total magnetic field, where the International Geomagnetic Reference Field was not removed.
Use Cases
Identify geological structures and lithological units based on magnetic field variations.
Support mineral exploration targeting by mapping magnetic anomalies indicative of ore deposits.
Integrate with other geophysical datasets for regional geological interpretation.
Assess the magnetic signature of the subsurface for academic research in geophysics.
Strengths
Data was collected with high-sensitivity magnetometers (0.005 nT).
Flight lines were designed with specific spacings (800 m traverse, 2400 m control) and a low terrain clearance (250 m) for detailed resolution.
The flight path was recovered using post-flight differential GPS corrections and video ground images.
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.
