Australian National Gravity Data Collection for Onshore and Offshore Surveys

Australian continent and regional marine gravity data measuring subsurface rock density changes. The collection contains onshore and offshore data acquired by Commonwealth, State, NT Governments, and the private sector for resource assessment. It was last updated on 2026-06-04.

Use Cases

• Model subsurface rock type distribution based on gravity anomaly measurements.
• Assess mineral and hydrocarbon resource potential based on inferred density structures.
• Integrate gravity data with other geophysical surveys for regional geological mapping.

Strengths

• Includes both onshore and offshore gravity survey data.
• Aggregates data from multiple government and private sector sources.
• Last updated date of 2026-06-04 is provided.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data may reflect geographic or source bias inherent to data_gov_au.
