Complete Bouguer Gravity Anomaly Grid of Onshore Australia, 2016 Data

1,391,556 gravity stations from the Australian National Gravity Database and a 2013 Riverina survey were used to generate this grid. The data was acquired by government, industry, and academic sources from the 1940s onward. The grid shows complete Bouguer anomalies over onshore continental Australia, with terrain corrections applied using bathymetry and topography data.

Use Cases

• Modeling subsurface density variations based on the complete Bouguer anomaly values.
• Mineral and resource exploration targeting based on regional gravity anomaly patterns.
• Geological mapping and tectonic studies of the Australian continent using the gravity grid.
• Integrating gravity data with other geophysical datasets for joint inversion studies.

Strengths

• Derived from a large base of approximately 1.8 million gravity observations, using 1,391,556 specific stations.
• Incorporates data from multiple sources including Commonwealth, State, and Territory Governments, industry, and universities.
• Applies terrain corrections using both offshore bathymetry and onshore topography data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic or temporal bias inherent to the aggregated sources.
