Australian Continental Moho Depth Model from Seismic and Gravity Data

Geoscience Australia Data compiled a refined model of the Moho depth across the Australian continent. The dataset integrates over 25,000 km of full-crustal reflection profiles with portable seismic station results, marine reflection data, and gravity inversion estimates. The work was published in Geophysical Journal International in January 2023.

Use Cases

• Modeling crustal thickness variations based on integrated seismic and gravity data.
• Analyzing rapid changes in Moho depth across the continent based on dense sampling.
• Studying continent-ocean transitions based on gravity inversion results.
• Investigating crustal structure in previously poorly sampled regions like the Lake Eyre Basin.

Strengths

• Integrates over 25,000 km of interpreted reflection transects.
• Combines multiple data sources including portable seismic stations, marine reflection, and gravity inversion.
• Provides full continental coverage, though some desert areas have limited sampling.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Some desert areas remain with limited sampling, as noted in the description.
