Australian Fundamental Gravity Network: Modernization and Coverage Expansion

Australia's Fundamental Gravity Network (AFGN) is being modernized to support resource exploration, geodesy, and environmental studies. The work involves cleaning station data, expanding coverage in under-served regions, and investigating new gravimeter technologies. Presented at the 2025 Australasian Exploration Geoscience Conference (AEGC), the data is managed by Geoscience Australia.

Use Cases

• Calibrating regional gravity surveys based on the network's long spatial wavelength coherence
• Planning resource exploration campaigns based on the expanded network coverage in under-served regions
• Assessing environmental changes using high-precision gravity data from verified stations
• Evaluating field-based absolute gravimeter technologies based on the investigation of alternative instruments

Strengths

• Describes a national-scale network undergoing active modernization
• Focuses on high-precision data for long spatial wavelength coherence
• Work includes expanding coverage in under-served regions

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
