A 200 m grid interpolated from levelled total field magnetic data collected by Fugro Airborne Surveys between March 7 and May 1, 2003. The survey used a Cessna Caravan aircraft with a 0.005 nT sensitivity cesium vapour magnetometer and a nominal traverse line spacing of 800 m. The International Geomagnetic Reference Field has not been removed from the magnetic total field.
Use Cases
- Model subsurface geological structures based on magnetic anomaly patterns.
- Assist mineral exploration targeting based on magnetic field gradients.
- Validate or integrate with other geophysical surveys based on the 200 m grid resolution.
- Study regional magnetic field characteristics based on the levelled total field values.
Strengths
- Survey conducted with a 0.005 nT sensitivity instrument, suggesting high-precision measurements.
- Data levelled and interpolated to a 200 m grid, providing a consistent spatial resolution.
- Flight path recovered using differential GPS and video camera, likely improving positional accuracy.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- The International Geomagnetic Reference Field has not been removed, which may affect direct interpretation.
- Row count is unknown, which may limit suitability assessment.
