Marine Sediments database (MARS) (GA)

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.It includes: Core, Dredge, Grab, Water, Column and Camera samples.Format:Data can be downloaded in CSV format for: - All sample data, - CaCO3 as mud/sand/gravel/bulk, - CaCO3 +grain size as mud/sand/gravel/[bulk|mean], - Grain size as mud/sand/gravel/mean, - Grain size for laser, - Grain size all, - Minerals with method of ICP-MS/XRF- Salinity.The full database is a 500 MB CSV.For 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.This 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/).The full database contains samples of the following type (this list is taken for data from 2010 - 2015): PROPERTY    UOMAg    ppmAl    mg/kgAl2O    %Al2O3    w%Al2O3    %As    ppmAs    mg/kgAuthigenic-P    umol/gBa    ppmBe    ppmBi    ppmCa    mg/kgCaCO3    %CaO    w%CaO    %carbonate content    %Cd    ppmCd    mg/kgCe    ppmChlorin index    Chlorophyll a    ug/gChlorophyll b    ug/gChlorophyll c    ug/gCl    ppmCo    mg/kgCo    ppmCr    mg/kgCr    ppmCs    ppmCu    mg/kgCu    ppmdelta 13C    o/oodelta 15N    o/ooDetrital-P    umol/gDy    ppmEr    ppmEu    ppmFe    mg/kgFe2O3    %Fe2O3TOT    w%Ga    ppmGa    mg/kgGd    ppmGe    ppmgrain size    %grain size    umgrain size    No unitgrain size    m2/gHf    ppmHo    ppmK2O    w%K2O    %La    ppmLu    ppmMg    mg/kgMgO    w%MgO    %MINERAL    w%MLOI    w%Mn    mg/kgMnO    w%MnO    %Mo    ppmMo    mg/kgNa2O    w%Na2O    %Nb    ppmNd    ppmNi    mg/kgNi    ppmO2    mmol/m2/dOrganic-P    umol/gOxide Associated-P    umol/gP    mg/kgP2O5    w%P2O5    %Pb    ppmPb    mg/kgpH    Phaeophytin    ug/gporosity    %Pr    ppmRb    ppmS    mg/kgsalinity    Sb    ppmSc    ppmSc    %Se    mg/kgSiO2    w%SiO2    %Sm    ppmSn    ppmSO3    w%SO3    %SOD    %/g/dspecific surface area    m2/gSr    ppmTa    ppmTb    ppmTCO2    mmol/m2/dTh    ppmTiO2    w%TiO2    %TKN    %TN    %TOC    %Total sediment metabolism    umol/cm3/dTotal sediment metabolism    umol/g/dU    ppmV    mg/kgV    ppmW    ppmWater temperature    degCY    ppmYb    ppmZn    mg/kgZn    ppmZr    ppm
