Over 15,000 seabed samples provide textural composition, particle size statistics, and calcium carbonate values across the Australian marine region. Geoscience Australia extracted this data from its Marine Sediment Database, an online resource of approximately 2.6 million entries. The sample set spans coastal, shelf, slope, and deep ocean locations, covering the extent of the AusBathyTopo 250m 2023 grid.
Use Cases
- Seabed characterisation based on sediment texture and carbonate content.
- Sediment transport modelling based on particle size distribution statistics.
- Habitat characterisation based on seabed sediment properties.
- Fundamental geological research based on a continental-scale sample collection.
Strengths
- Over 15,000 seabed samples provide substantial spatial coverage.
- Derived from a national database containing approximately 2.6 million entries.
- Includes multiple analytical properties like texture, particle size, and carbonate values.
- Covers a wide geographic range from coast to deep ocean across the Australian region.
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 or source bias inherent to the original survey collection.
