Refined Moho Depth Model Across the Australian Continent

A continental-scale model of the Moho depth beneath Australia, integrating multiple geophysical data sources. The dataset combines results from over 25,000 km of full-crustal reflection profiles, portable seismic station deployments analyzed by receiver function and autocorrelation methods, marine reflection results, and earlier refraction studies. 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 the integrated Moho depth estimates.
• Analyzing rapid changes in Moho structure suggested by the dense sampling.
• Studying the continent-ocean transition using results from gravity inversion.
• Investigating lateral contrasts in crustal thickness, such as around the Lake Eyre Basin.

Strengths

• Integrates data from over 25,000 km of reflection transects.
• Provides full continental coverage for Australia, combining new portable seismic, marine, and legacy data.
• Employs a weighted construction approach to handle rapid changes in Moho depth.

Limitations

• Some desert areas remain with limited sampling.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
