The HSSediment table contains disaggregated data on hazardous substances in sediment, measured at Eionet-Water transitional, coastal or marine water monitoring stations, provided by national sources only. Each station has been assigned a unique Waterbase identifier (WaterbaseID) which can be used to link the Quality data with their respective Stations data.
year of aggregation period (aggregated data sets), or year in which sample taken (disaggregated data sets), in format YYYY. Year should be no later than that requested in the last Eionet-Water data request.
month in which sample taken, values in range 0-12. If the month value has not been supplied the value will be 0.
day in which sample was taken, values in range 0-31. If the day value has not been supplied the value will be 0.
Top of sediment layer
top of analysed sediment layer measured from the sediment surface in cm. Value will be 0 if the top of the sediment layer is the surface.
Bottom of sediment layer
bottom of analysed sediment layer measured from the sediment surface in cm.
concentration of determinand in sample. In TCM data, concentration values recorded as below the limit of detection or determination should contain the limit of detection or determination in the concentration field, with the LimitFlag field set to <.
Bottom depth of sediment
depth of sea bottom at sampling site in m.
organic carbon content as a percentage of total dry weight.
Dry wet ratio
ratio of dry weight to wet weight as a percentage.
abbreviation of EEA Member or Collaborating country. ISO 3166-alpha-2 code elements.
internally produced, unique identifier used to represent the monitoring station for rivers, lakes, transitional, coastal and marine waters, and water quantity, in the format CountryCode_WaterDataSet_NationalStationID (e.g. AT_RV_001), or the groundwater body, in the format CountryCode_WaterDataSet_EWN-Code (e.g. AT_GW_AT001).
unique sample identifier required if multiple samples taken on same day. SampleID default value is 0.
Chemical Abstract Service Number of the hazardous substance, as defined in the codelist.
