Complete Bouguer Gravity Anomaly Grid of Onshore Australia, 2016

Approximately 1.8 million gravity observations from the 1940s to 2016 were used to generate this grid. The data combines 1,371,998 stations from the Australian National Gravity Database and 19,558 from a 2013 New South Wales survey, processed with terrain corrections from bathymetry and topography. It was produced by Geoscience Australia Data.

Use Cases

• Model subsurface density variations based on the complete Bouguer anomaly values.
• Support mineral and resource exploration targeting based on gravity anomaly patterns.
• Integrate with other geophysical datasets for regional geological interpretation based on the onshore continental coverage.
• Calculate terrain corrections for gravity surveys using the described bathymetry and topography methodology.

Strengths

• Derived from a large-scale source of approximately 1.8 million gravity observations.
• Integrates data from multiple sources, including 1,371,998 ANGD stations and 19,558 from a dedicated 2013 survey.
• Includes terrain corrections calculated 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.
