Australian Continental Moho Depth Model from Seismic and Gravity Data

Australia's Mohorovičić discontinuity (Moho) depth is mapped using a combination of seismic and gravity data. The dataset integrates results from over 25,000 km of reflection transects, portable seismic stations, and marine surveys to provide continental coverage. 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 inversion data.
• Analyzing rapid changes in Moho depth across tectonic boundaries mentioned in the description.
• Studying the continent-ocean transition zone using gravity-derived Moho estimates.
• Comparing crustal structure in newly sampled regions like the Lake Eyre Basin with older cratonic zones.

Strengths

• Integrates data from over 25,000 km of full-crustal reflection profiles.
• Combines multiple data sources: receiver functions, autocorrelation, reflection profiles, marine results, and gravity inversion.
• Provides full continental coverage for Australia, improving on earlier models.

Limitations

• Some desert areas are noted to have limited sampling.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and specific file format details are unknown.
