Refined Moho Depth Model for the Australian Continent

A continental-scale model of Moho depth across Australia, integrating over 25,000 km of interpreted reflection transects with portable seismic station data, marine reflection results, and earlier refraction studies. The dataset was published in Geophysical Journal International in January 2023 and is provided by Geoscience Australia Data. It offers full continental coverage, though some desert areas have limited sampling.

Use Cases

• Modeling crustal thickness variations based on integrated seismic and gravity data.
• Analyzing rapid changes in Moho depth across tectonic boundaries.
• Studying continent-ocean transition zones using gravity inversion results.
• Investigating crustal structure in specific regions like the Lake Eyre Basin.

Strengths

• Integrates over 25,000 km of interpreted full-crustal reflection transects.
• Combines multiple data sources including portable seismic stations, marine results, and gravity inversion.
• Provides full continental coverage for Australia.

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.
• Some desert areas remain with limited sampling, as noted in the description.
