It 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. {"type": "Polygon", "coordinates": [[[45.0, -90.0], [168.0, -90.0], [168.0, -9.0], [45.0, -9.0], [45.0, -90.0]]]} 45.0 168.0 -90.0 -9.0 Oceans | Marine Sediments | Sediment Characteristics Oceans | Marine Sediments | Sediment Composition Oceans | Marine Sediments | Sediment Grain Size Oceans | Marine Sediments | Stratigraphic Sequence
