Complete Bouguer Gravity Anomaly Grid of Onshore Australia, 2016

Onshore continental Australia is covered by a grid of complete Bouguer gravity anomalies. The grid was generated from approximately 1.39 million gravity stations, combining data from the Australian National Gravity Database and a 2013 regional survey. Data acquisition spans from the 1940s to the present, contributed by government, industry, and academic sources.

Use Cases

• Modeling subsurface density variations based on the complete Bouguer anomaly values.
• Integrating gravity data with other geophysical surveys for regional geological interpretation.
• Supporting mineral and resource exploration targeting based on anomaly patterns.
• Studying crustal structure and tectonic features across the Australian continent.

Strengths

• Derived from a substantial base of approximately 1.39 million gravity station observations.
• Incorporates terrain corrections calculated from both offshore bathymetry and onshore topography.
• Data collection represents a long temporal range, from the 1940s to 2016.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and spatial resolution of the grid are unknown, which may limit suitability assessment.
