Australian Gravity Provinces and Units with 125 Defined Regions

125 gravity provinces and their subdivisions have been defined and named across Australia and its continental margins. The dataset rationalizes features from historical and modern land and marine reconnaissance gravity surveys, which now have virtually complete coverage. It is published by the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Map regional crustal structure based on defined gravity province boundaries.
• Analyze gravity field uniformity based on properties like contour trend or gravity level.
• Compare historical survey interpretations with the modern rationalized regional pattern.
• Standardize nomenclature for discussing regional gravity features in publications.

Strengths

• Defines 125 specific gravity provinces and their units.
• Based on land and marine gravity surveys with virtually complete coverage over Australia.
• Rationalizes historical interpretations into a consistent regional pattern.

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 bias inherent to data_gov_au.
