Capel and Faust Basins Marine Magnetic Survey Data, 2006

Total magnetic intensity (TMI) data measures variations in the Earth's magnetic field caused by rock-forming minerals in the crust. The data were acquired in 2006 for Geoscience Australia as part of the GA302 Capel and Faust Basins MSS survey, which also collected seismic, gravity, and bathymetry measurements. Processed data is checked for quality by GA geophysicists to ensure it is fit-for-purpose for revealing sub-surface geological structure.

Use Cases

• Modeling geological structure of the sub-surface based on magnetic anomaly data.
• Correlating magnetic data with other geophysical measurements like seismic reflection and gravity mentioned in the survey.
• Identifying rock types and mineral content based on magnetic susceptibility contrasts.
• Supporting marine resource exploration and basin analysis in the Capel and Faust region.

Strengths

• Data underwent standard processing to isolate the magnetic response of subsurface rocks.
• Quality was checked by Geoscience Australia geophysicists to ensure fitness-for-purpose.
• Data is part of a multi-method survey that included seismic, gravity, and swath bathymetry.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset scale are unknown, which may limit suitability assessment.
• Freshness should be verified as the underlying survey was conducted in 2006.
