Australian Continental Moho Depth Estimates From Seismic Surveys

25,000 km of full-crustal reflection profiles interpreted for Moho structure are integrated with portable seismic station deployments and marine reflection results. The dataset provides full continental coverage for Australia, though some desert areas have limited sampling. These results were published in Geophysical Journal International in January 2023.

Use Cases

• Model crustal thickness variations by analyzing interpolated Moho depth surface across the continent.
• Identify rapid changes in Moho depth using weighted estimates from receiver function and autocorrelation methods.
• Study the continent-ocean transition zone using Moho results derived from gravity inversion.
• Compare crustal thickness in regions like the Lake Eyre Basin against cratonic zones to the west.
• Validate and refine continental-scale geophysical models with the dense sampling of Moho estimates.

Strengths

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

Limitations

• Some desert areas remain with limited sampling, creating data gaps.
• Specific row count, column details, and sample data are unavailable.
• Primary data format is HTML, which may require parsing for quantitative analysis.
