Australian Geophysical Data for Onshore and Marine Areas

Australia has world-class coverage of onshore and near-offshore airborne total magnetic intensity (TMI) data, onshore airborne gamma-ray spectrometric data, and ground gravity data. Shipborne TMI and gravity data cover parts of Australia's marine jurisdiction. The dataset is provided by the Australian Ocean Data Network and was last updated on 2026-06 04.

Use Cases

• Model subsurface geology based on total magnetic intensity data.
• Analyze mineral composition based on airborne gamma-ray spectrometric data.
• Map gravitational anomalies for resource exploration based on ground and shipborne gravity data.
• Conduct integrated geophysical studies by combining magnetic and gravity datasets.

Strengths

• Description cites 'world-class coverage' of key geophysical data types.
• Data covers both onshore and near-offshore/marine jurisdictions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
