Waterbase - TCM: QualitySedimentD

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

The QualitySedimentD 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 and Pressures data.

Table definition

Fraction	Fraction	upper limit of particle size in analysed fraction expressed in µm. Blank if whole sediment has been analysed.	int(4)	0
Year	Year	year of aggregation period, or year in which sample taken, in format YYYY.	int(4)	0
Month	Month	month in which sample 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
Determinand	Determinand	determinand name.	nvarchar(200)	0
Unit	Unit	unit of measurement.	nvarchar(30)	0
Sampler	Sampler	name of sampling equipment used at transitional, coastal or marine water monitoring station.	nvarchar(200)	0
WaterbaseID	WaterbaseID	internally produced, unique identifier used to represent the monitoring station for rivers, lakes, transitional, coastal and marine waters and water quantity, or groundwater body, in the format CountryCode_WaterDataSet_NationalStationID (e.g. GB_RV_12345).	nvarchar(200)	-1
SampleID	Sample ID	unique sample identifier required if multiple samples taken on same day. SampleID default value is 0.	nvarchar(50)	0
CaSNo	Chemical Abstract Service Number	Chemical Abstract Service Number of determinand.	nvarchar(20)	0
SedimentBottom	Bottom of sediment layer	bottom of analysed sediment layer measured from the sediment surface expressed in cm. Value "-1" indicates data not available.	float(8)	0
OrganicCarbon	Organic carbon	mean organic carbon content expressed as % of total dry weight.	float(8)	0
DryWetRatio	Dry wet ratio	mean ratio of dry weight to wet weight expressed as %.	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
BottomDepth	Bottom depth of sediment	bottom depth where the sediment sample was taken at transitional, coastal or marine water monitoring station expressed in m, measured from the water surface.	float(8)	0
SedimentTop	Top of sediment layer	top of analysed sediment layer measured from the sediment surface expressed in cm. Value "-1" indicates data not available.	float(8)	0
Basis	Basis	basis of aggregate: D = Dry, W = Wet.	varchar(1)	0
CountryCode	Country Code	ISO 3166-alpha-2 code elements.	varchar(2)	0
GrainType	Grain type	sediment type description if no analysis of grain size: M = Mud, FS = Fine sand, MS = Middle sand, CS = Coarse sand, G = Gravel.	varchar(2)	0
LimitOfDetectionFlag	Limit of detection flag	flag to indicate sample below analytical limit of detection in format <.	varchar(1)	0
