Complete Bouguer Gravity Anomaly Grid of Onshore Australia, 2016

The Complete Bouguer Gravity Anomaly Grid of Onshore Australia 2016 is derived from over 1.39 million gravity stations from the Australian National Gravity Database and a 2013 Riverina survey. The grid shows terrain-corrected Bouguer anomalies over continental Australia, using data acquired by governments, industry, and academia from the 1940s onward.

Use Cases

• Model subsurface geological structures based on gravity anomaly patterns.
• Support mineral and resource exploration by identifying density variations.
• Integrate with other geophysical datasets for regional geological studies.
• Calculate terrain corrections for gravity surveys using bathymetry and topography data.
• Analyze long-term gravity data trends from historical surveys spanning decades.

Strengths

• Integrates 1,371,998 stations from the national database and 19,558 from a dedicated 2013 survey.
• Applies terrain corrections using both offshore bathymetry and onshore topography.
• Aggregates data from multiple sources (government, industry, academia) collected from the 1940s to 2016.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
