MARine Sediment (MARS) 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 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.海洋沉积物（MARine Sediment, MARS）数据库收录了澳大利亚海洋管辖范围（包括澳大利亚南极领地）内采集的海底沉积物样品的详细特征信息。该数据库涵盖调查与样品相关资料，包括采样点位、水深及样品描述等内容；同时包含沉积物的各类定量分析数据，如粒度、泥质、砂质、砾石及碳酸盐含量、矿物组成、年代测定结果、地球化学特性，以及岩心样品的物理属性，具体包括体积密度、纵波速度、孔隙度与磁化率等。如有可用资源，将附带相关图像与图表。目前MARS数据库已收录超过40000条样品及子样品记录，以及约200000条描述这些样品特征的记录，后续将持续收录新的可用数据。
