MARS: Marine Sediment Database for Australia's Seabed

Approximately 100,000 sample records detail seabed sediment characteristics across Australia's marine jurisdiction, including the Australian Antarctic Territory. The MARS database, managed by Geoscience Australia, includes analytical properties like grain size, carbonate content, and geochemistry. New data are added as they become available.

Use Cases

• Model seabed stability and composition based on grain size and mineralogy data.
• Analyze historical oceanographic conditions using sediment age determinations.
• Map carbonate content and geochemical properties for environmental baseline studies.

Strengths

• Approximately 100,000 sample records provide a substantial data volume.
• Samples span coastal, continental shelf, and deep-sea locations, offering broad geographic coverage.
• Includes multiple analytical properties such as grain size, carbonate content, and age determinations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified despite a last updated date of 2026-04-30.
