Marine Sediments Database

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 survey and sample information such as locations, water depths and sample descriptions. Data are also provided from quantitative analyses of the sediments, such as grain size, mud, sand, gravel and carbonate concentrations, mineralogy, age determinations, geochemical properties, and physical attributes for down-core samples including bulk density, p-wave velocity, porosity and magnetic susceptibility. Images and graphics are presented, where available. MARS currently holds >40,000 sample and sub-sample records, and approximately 200,000 records describing the characteristics of these samples. New data are being added as they become available.
