17. Extension of the EEA European Topic Centre’s Work Program to the West Balkan Countries in the field of water 17 Workshop 7-8 November 2006, Belgrade Possible problems with using the data dictionary: Many repetitions of identical code tables Field descriptions that cover different data sets within the TCM Data Dictionary Some unneeded details Have prepared a version with Bookmarks for more easy reference Important specs: Headings Field types (Integer/float/text) Code values Allowed value range Not important: Some details of numeric format

18. Extension of the EEA European Topic Centre’s Work Program to the West Balkan Countries in the field of water 18 Workshop 7-8 November 2006, Belgrade Extracts from methodology notes in Data Dictionary: ……… Data … should be derived from existing national and/or regional monitoring networks Data should provide a general overview, based on truly comparable data, of water quality at a European level Data already submitted to the Marine Conventions need not be resupplied through the Eionet-Water process ……… Technical issues: –Field headings as described in the data dictionary –Excel worksheets should contain values, not formulae –Missing information should be represented as null or empty fields –The character µ (micro) used in measurement units like µmol/l and µg/kg must be set in a persistent way For each table type: –Determinands detailed in codelist. –List is not exhaustive. –Provide name (and CAS Number, if appropriate) of any additional determinands included in data submission.

22. Extension of the EEA European Topic Centre’s Work Program to the West Balkan Countries in the field of water 22 Workshop 7-8 November 2006, Belgrade Input and pressure data Current EEA design is modelled on OSPAR RID data, which are received, but not currently used. Flux stations (Riverine input and pressure data): –River stations near the mouth, Could be part of river data set. –Not always individual rivers, can be summary for coastline Direct discharges: –Related to Waterbodies in current model –Can be referring to two topological types: Point Sources Diffuse direct runoff (length of coastline) –Not meaningful as long as Waterbodies are not well-defined (or even mandatory) anywhere in the data model

23. Extension of the EEA European Topic Centre’s Work Program to the West Balkan Countries in the field of water 23 Workshop 7-8 November 2006, Belgrade Room for improvement of Waterbase design: Connect to definition of marine waterbodies Adjust data design for flux stations to describe point sources and diffuse direct runoff Riverine input and direct discharges combined into one data set on loads. Refer data to well-defined GIS base data set (definitions of point locations, shapes or shape boundary sections). Combine with river/lake data set? Use natural smallest unit for Pressure data: –Intersections of division into catchment by defined waterbody and administrative region –Reporting on smallest unit, and aggregation by river basin across administrative borders –Retention on transfer through transport system should be taken into account

24.

Unit info must be accompanied by information of Basis (Wet, Dry, Lipid for biota, Wet, Dry for Sediment) No need to rewrite data to standard units (done automatically in processing), but units should be declared if not selfevident for check against conversion table) Basis should be in designated field (“µg/kg”, “W”) and not built into the unit (“µg/kg ww”) Determinand names May use defined full names or codes (list available) Other names or codes may be acceptable as aliases –if clearly defined –If not in conflict with other names, codes or aliases

25. Extension of the EEA European Topic Centre’s Work Program to the West Balkan Countries in the field of water 25 Workshop 7-8 November 2006, Belgrade Status of EIONET data delivery Update 2005:

26. Extension of the EEA European Topic Centre’s Work Program to the West Balkan Countries in the field of water 26 Workshop 7-8 November 2006, Belgrade Not all delivered data are processed. Rejecting data may be due to layout or format: Non-English determinand names etc. –(OK in Geographical names) Different data types mixed within the same table (seawater, biota etc.) Many separate tables, requiring editing before being combined –Excel files with decorated layout for printing –MS-Word documents with tables of elaborate design Irregular data formats that takes working time to transform –Coordinates given as text strings (59°7’15”) instead of decimal degrees

27. Extension of the EEA European Topic Centre’s Work Program to the West Balkan Countries in the field of water 27 Workshop 7-8 November 2006, Belgrade Rejecting data may also be due to problems with content: Large amount of unreasonable, unexplained values –0 values or <0 values for hazardous substances missing values set to 0 by courtesy of Bill Gates? special information codes? –obvious mismatch between numbers and units Large amounts of values marked as preliminary Large amounts of data where required information is missing –no unit given, or basis not specified for biota –No information about within-core depths of analysed sediment –missing information about stations not provided previously Data contents do not cover what is requested Only aggregated data submitted May accept data set, but reject individual records not meeting requirements

Make sure stations are defined with coordinates –Degrees with fraction as decimals Use standard determinand names or codes –(Or include a lookup list) Edit tables into ”clean” database-type layout (one heading row + data rows) Excel macro is available Please use the template, but check with Data Dictionary –Important: Use defined codes. –Not important: Detailed spec. of length and numerical precision of ordinary floating-point values
