Marine Sediments (MARS) Database

Created 20/01/2026

Updated 20/01/2026

The MARine Sediment (MARS) database contains detailed information on seabed sediment characteristics for samples collected from Australia's marine jurisdiction, including the Australian Antarctic Territory. It is an important scientific resource that includes sediment properties from seabed and sub-seabed samples spanning coastal, continental shelf and deep sea locations. Analytical properties include grain size, carbonate content, mineralogy, geochemical properties and age determinations. MARS currently holds approximately 100,000 sample records and new data are being added as they become available.

Please contact us at ausseabed@ga.gov.au if you wish to contribute marine sediment data to the MARS database.
