The Quality table contains disaggregated data on nutrients, oxygen and organic matter in seawater, 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.
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 <.
depth at which sample taken in m below water surface
salinity of sample.
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.
unit of measurement.
Limit of detection or determination flag
flag to indicate sample below analytical limit of detection or determination in format <.
vertical position relative to thermocline at transitional, coastal and marine water station. AT=above thermocline, IT=in thermocline, BT=below thermocline.
vertical position relative to halocline at transitional, coastal and marine water station. AH=above halocline, IH=in halocline, BH=below halocline.
To save electricity, before you leave don’t forget to unplug as many appliances as is possible. If the appliances are still plugged in, they continue to use up energy. even if you switch them off.
