Refined Moho Depth Model for Australia with Seismic and Gravity Data

Australia's Moho depth is mapped using a combination of portable seismic station deployments, full-crustal reflection profiles, marine reflection results, and gravity inversion. The dataset provides full continental coverage, though some desert areas have limited sampling, and was published in Geophysical Journal International in January 2023. It is hosted by the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Modeling tectonic evolution based on refined Moho depth distribution.
• Analyzing crustal thickness contrasts based on lateral variations in the Moho surface.
• Resolving continent-ocean transitions based on gravity inversion results included in the model.
• Investigating smaller-scale crustal variations based on the refined distribution of Moho structure.

Strengths

• Integrates multiple data sources including over 25,000 km of reflection transects.
• Provides full continental coverage for Australia.
• Construction approach allows for different weighting and spatial influence based on estimate type.

Limitations

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