Refined Moho Depth Model Across Australia Integrating Seismic and Gravity Data

Australian continent-wide estimates of Moho depth, derived from multiple geophysical surveys. The dataset combines results from portable seismic stations, full-crustal reflection profiles spanning more than 25,000 km, marine reflection results, earlier refraction studies, and gravity inversion. It was published in Geophysical Journal International in January 2023 and is hosted by the Australian Ocean Data Network.

Use Cases

• Modeling crustal thickness variations based on integrated seismic and gravity data.
• Analyzing rapid changes in Moho depth and smaller-scale structural variations mentioned in the description.
• Studying continent-ocean transition zones using gravity inversion results with low weighting.
• Investigating lateral crustal thickness contrasts, such as around the Lake Eyre Basin and cratonic zones.

Strengths

• Integrates data from multiple methods: receiver function, autocorrelation, reflection profiles (>25,000 km), marine reflection, refraction, and gravity inversion.
• Provides full continental coverage for Australia, though some desert areas have limited sampling.
• Construction method allows different weighting and spatial influence based on the nature of the estimate.

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 and specific file formats are unknown, which may limit suitability assessment.
