Complete Bouguer Gravity Anomaly Image of Onshore Australia, 2016

Geoscience Australia Data produced a complete Bouguer gravity anomaly image for onshore Australia as of 2016. The image was generated from approximately 1.39 million gravity stations, combining data from the Australian National Gravity Database and a 2013 Riverina survey. Data acquisition spans from the 1940s to the present day, contributed by government, industry, and research entities.

Use Cases

• Model subsurface density variations based on complete Bouguer anomaly data.
• Support mineral and resource exploration by interpreting gravity anomaly patterns.
• Integrate with other geophysical datasets for regional geological studies.
• Apply image enhancement techniques for improved visual interpretation of geophysical features.

Strengths

• Derived from approximately 1.39 million gravity station observations.
• Incorporates data from a long temporal range, spanning from the 1940s to 2016.
• Terrain corrections applied using both offshore bathymetry and onshore topography.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is delivered as processed image files (PDF, ZIP); raw numerical grids may not be directly accessible.
