Capel and Faust Basins Marine Magnetic Survey Data from 2006

Total magnetic intensity (TMI) data measures variations in the Earth's magnetic field caused by rock-forming minerals. The processed line dataset from the GA302 survey was acquired in 2006 for Geoscience Australia and includes seismic, gravity, magnetic, and bathymetry measurements. GA geophysicists checked the data quality to ensure it is fit-for-purpose.

Use Cases

• Map geological structures based on magnetic anomaly patterns.
• Integrate magnetic data with seismic reflection and gravity measurements for multi-physics analysis.
• Interpret sub-surface rock composition using processed total magnetic intensity data.
• Validate geological models with quality-checked marine survey data.

Strengths

• Data processed via standard methods to isolate the response from rocks.
• Quality checked by GA geophysicists to ensure fitness for purpose.
• Acquired alongside other pre-competitive data like seismic reflection and gravity.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified; the last metadata update is 2026-04-16.
