1. Station mapping Eionet-Water vs. Water Framework Directive (WFD) Hermann Peifer, EEA Jørgen Nørrevang Jensen, ICES Eionet Workshop for Marine and Coastal Environment 14-15 May 2008, EEA, Copenhagen

2. What is the issue? a)Transitional and coastal stations reported under Eionet data collection b)Transitional and coastal stations reported under the Water Framework Directive Question: In how far are we able to map the 2 sets of stations reported under a) and b) in order to ensure consistency between delivered stations and monitoring data?

3. Water Framework Directive: River Basin Districts

4. WFD Art. 8 Monitoring Stations Rivers Lakes Transitional Coastal

6. Done in 2007: Mapping of river, lake and ground- water stations

7. Mapping of Coastal and Transitional stations Mapping technique Visual Basic script: That match each station in one station table (WFD) with the best closest matching station in a second station table (e.g. EIONET Calculates the distance between the stations in this match

8. Mapping WFD CT stations against EIONET CT stations Only 15 stations maps exactly Using a 1 km range 1336 WFD stations gets a match in the EIONET station table Some stations marked as EIONET stations in WFD do not match any station

9. Mapping WFD CT stations against ICES Station dictionary (OSPAR) stations Only 2 stations maps exactly Using a 1 km range 319 WFD stations gets a match in the Station dictionary table

10. The ideal situation A common list of stations with: Nominal coordinates and unique names Information on which monitoring programme these stations belongs to (e.g. stations in Kattegat belongs often to both OSPAR and HELCOM, and maybe also to WFD) Information on the acceptable geographic range around these station (in case the nominal coordinates are not used)

11. Question to NRCs If a national overview of station-belonging (to, e.g., the WFD, EIONET, OSPAR, HELCOM, or MEDPOL) exists for your country, what are the default/nominal positions and the accepted range of positions for those stations? (If e.g. the default position is x longitude and y latitude, is the actual coordinate of x ± 0.1 and y ± 0.1 acceptable for this station?).
