Summary: | 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 also includes the Geat Barrier Reef (GBR). 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.\n\nIt includes: Core, Dredge, Grab, Water, Column and Camera samples.\n\nFormat:\nData can be downloaded in CSV format for: \n- All sample data, \n- CaCO3 as mud/sand/gravel/bulk, \n- CaCO3 +grain size as mud/sand/gravel/[bulk|mean], \n- Grain size as mud/sand/gravel/mean, \n- Grain size for laser, \n- Grain size all, \n- Minerals with method of ICP-MS/XRF\n- Salinity.\n\nThe full database is a 500 MB CSV.\n\nFor the eAtlas the "CaCO3 +grain size as mud/sand/gravel/[bulk|mean]" CSV file was downloaded and converted to a shapefile for visualisation. This is available for download from this record.\n\nThis metadata is not an authoritative source and was developed for the eAtlas. Please check or contact Geoscience Australia for authoritative metadata. The original data is available for download via the Marine Sediments (MARS) Database Search (http://www.ga.gov.au/oracle/mars/).\n\nThe full database contains samples of the following type (this list is taken for data from 2010 - 2015): ... |
