MARS: Marine Sediment Characteristics for Australia's Seabed

Australia's marine jurisdiction, including the Australian Antarctic Territory and the Great Barrier Reef, is covered by this seabed sediment database. The MARS database holds over 40,000 sample records with approximately 200,000 characteristic records, including grain size, carbonate content, mineralogy, and geochemistry. Data are provided by Geoscience Australia and the Australian Ocean Data Network, with new data added as available.

Use Cases

• Model seabed carbon storage based on carbonate concentration data.
• Analyze sediment transport patterns based on grain size distribution data.
• Map mineral resource potential based on geochemical and mineralogical properties.
• Study paleoenvironmental changes based on down-core physical attributes like porosity and magnetic susceptibility.

Strengths

• Contains over 40,000 sample and sub-sample records with approximately 200,000 characteristic records.
• Includes a wide range of quantitative analyses such as grain size, carbonate content, mineralogy, and geochemistry.
• Covers a broad geographic scope including Australia's marine jurisdiction and the Australian Antarctic Territory.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for specific downloadable files is unknown, which may limit suitability assessment.
• The provided metadata is noted as not authoritative; users are directed to contact Geoscience Australia for authoritative metadata.
