Waterbase - TCM: QualityWaterD

This website has limited functionality with javascript off. Please make sure javascript is enabled in your browser.

The QualityWaterD table contains disaggregated data on nutrients, oxygen and organic matter in seawater, measured at Eurowaternet transitional, coastal or marine water monitoring stations. Each station has been assigned a unique Waterbase identifier (WaterbaseID) which can be used to link the Quality data with their respective Stations and Pressure data.

Table definition

Year	Year	year of aggregation period or year in which sample taken, in format YYYY.	int(4)	0
Month	Month	month in which sample was taken, values in range 0-12 (it is possible that the month has not been supplied, in which case the value will be 0).	int(4)	0
Day	Day	day in which sample was taken, values in range 0-31 (it is possible that the day has not been supplied, in which case the value will be 0).	int(4)	0
SampleID	Sample ID	unique sample identifier required if multiple samples taken on same day. SampleID default value is 0.	nvarchar(50)	0
Determinand	Determinand	determinand name.	nvarchar(200)	0
Unit	Unit	unit of measurement.	nvarchar(30)	0
SampleDepth	Sample depth	depth at which sample taken expressed as m below surface with value >=0.	float(8)	0
Salinity	Salinity	salinity of sample or salinity to which sample concentration is normalised in practical salinity units (psu).	float(8)	0
LimitOfDetection	Limit of detection	concentration for which there is a desirably small probability (around 5%) that the determinand will not be detected i.e. there is a 95% probability that the determinand will be detected.	float(8)	0
LimitOfDetermination	Limit of determination	the smallest concentration that can be distinguished from the analytical blank at a chosen level of statistical confidence (usually 95%).	float(8)	0
Concentration	Concentration	concentration of determinand in sample. For observations reported as below the analytical limit, the field will contain the upper (reporting) limit.	float(8)	0
ThermoPos	Thermocline position	vertical position relative to thermocline at transitional, coastal or marine water monitoring station: AT = Above thermocline, IT = In thermocline, BT = Below thermocline.	varchar(2)	0
HaloPos	Halocline position	vertical position relative to halocline at transitional, coastal or marine water monitoring station: AH = Above halocline, IH = In halocline, BH = Below halocline.	varchar(2)	0
CountryCode	Country code	ISO 3166-alpha-2 code elements.	varchar(2)	0
WaterbaseID	Waterbase ID	Internally produced, unique identifier used to represent the transitional, coastal or marine water monitoring station, in the format: CountryCode_WaterDataSet_NationalStationID (e.g. GB_TCM_12345).	varchar(200)	-1
LimitOfDetectionFlag	Limit of detection flag	flag to indicate sample below analytical limit of detection in format <.	varchar(1)	0
