Australian National Gravity Data for Onshore and Offshore Surveys

Gravity data measuring subsurface rock density changes, acquired from geophysical surveys across Australia and its marine region. The collection includes data from Commonwealth, State, NT Governments, and the private sector, managed by the Australian Ocean Data Network. The dataset was last updated on 2026-07-13.

Use Cases

• Model subsurface rock types based on gravity anomalies.
• Assess mineral and hydrocarbon resources based on inferred geological structures.
• Conduct regional geological mapping based on gravity survey data.

Strengths

• Includes both onshore and offshore gravity survey data.
• Aggregates data from multiple government and private sector sources.

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 as the last update is dated 2026-07-13.
