Australian Upper Mantle Structure from Seismic and Gravity Data

Australia and surrounding marine areas are analyzed using seismic refraction surveys and free-air gravity field measurements. The dataset comprises a published scientific paper investigating crustal mass variations and sub-crustal mantle density inferences. The Australian Ocean Data Network published this analysis, with a platform record last updated in April 2026.

Use Cases

• Modeling crustal mass distribution from inferred crustal layer densities and seismic refraction data.
• Investigating mantle compensation depth by analyzing Pn velocity variations and corresponding density changes at 60-100 km depths.
• Comparing sub-continental and sub-oceanic mantle properties using seismic velocity increases and suggested low-velocity layer depths.
• Assessing the strength of the sub-shield mantle by examining the discrepancy between high crustal mass and inferred mantle density.

Strengths

• Analysis covers the continent of Australia and surrounding marine areas.
• Integrates multiple geophysical data types: seismic refraction surveys and gravity field measurements.
• Platform record indicates recent metadata update in 2026.

Limitations

• Primary data is a published paper in PDF/HTML format, not raw measurement datasets.
• Specific row counts, column names, and original data file sizes are unavailable.
• Temporal range for the underlying seismic and gravity measurements is not specified.
