Geophysical Journal International published a refined Moho depth dataset for Australia in January 2023. It combines over 25,000 km of reflection transects with portable seismic station deployments, marine reflection results, and gravity inversion data to achieve full continental coverage. The dataset was constructed by the Australian Ocean Data Network using an approach that weights different data sources to resolve rapid changes in crustal thickness.
Use Cases
- Modeling crustal thickness variations based on combined seismic and gravity data.
- Analyzing rapid changes in Moho depth across the continent.
- Studying continent-ocean transition zones based on gravity inversion results.
- Investigating crustal structure in previously poorly sampled regions like the Lake Eyre Basin.
- Mapping smaller-scale variations in Moho structure across Australia.
Strengths
- Combines over 25,000 km of interpreted reflection transects.
- Integrates multiple data sources: receiver function, autocorrelation, reflection, refraction, and gravity inversion.
- Provides full continental coverage for Australia.
- Refined distribution reveals widespread smaller-scale variations in Moho structure.
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.
