Australian Ocean Data Network hosts a scientific paper analyzing seismic refraction and gravity measurements across Australia and surrounding marine areas. The study infers crustal and upper mantle densities to investigate mass compensation and structural variations. The dataset, last updated in June 2026, is available in PDF and HTML formats.
Use Cases
- Modeling crustal mass compensation based on inferred density variations from seismic and gravity data.
- Analyzing the relationship between Pn velocities and sub-crustal mantle densities mentioned in the description.
- Investigating structural differences between sub-continental and sub-oceanic mantle suggested by the analysis.
Strengths
- Analysis is based on seismic refraction surveys and gravity measurements across a continental scale.
- The study provides specific depth inferences, such as compensation at 80 to 100 km and 130 km.

Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the Australian and surrounding marine focus.
