EIONET Priority Data Flows:
EUROWATERNET 2003: Transitional, Coastal and Marine Waters
Further to my letter of 11 August 2003, I am writing to inform you of the detailed plans for the EUROWATERNET annual data flow update that is, as you know, one of the agreed EIONET Priority Data Flows.
This is the second, formal EUROWATERNET annual data flow for transitional, coastal and marine waters and will run from now until Friday 30 January 2004. Technical guidance is provided on the content and format of the data required, including templates and details of the method and structure of data exchange.
The EIONET Water Interest Group on CIRCLE is once again used to facilitate document sharing, data flows and communications between the ETC and NFPs/NRCs. Technical information on the data flow requirements is provided in the document: Guidance on Updating of Priority Data Flows on transitional, coastal and marine waters through EUROWATERNET and the Population of WATERBASE. Detail is provided on the determinands required, the temporal coverage, the type of data to be reported, the units of measurement, and also the method of data provision. Excel templates are also provided which summarise the data exchange formats.
The data sets to be collected through this exercise have been selected on the basis of their relevance to the core set of indicators for water and to the objectives and assessment needs of the Water Framework Directive, the Urban Waste Water Treatment Directive, the Nitrates Directive and the Dangerous Substances Directive. The first three are the major pieces of legislation that will drive EU water policy over the next 15-20 years. The second round of the consultation process for the overall EEA core set of indicators is still under way. However, as with last year's data flow, we will focus on those determinands for which we believe data will be needed whatever the final outcome of the consultation process. For example, we still expect that data on hazardous substances in biota and nutrients in seawater will continue to be needed even though the indicator descriptions may change during the consultation process.
Relationship to Marine Conventions
It is recognised that whilst some countries may have already made a data supply to the Marine Conventions, the time series are somewhat incomplete. It is therefore necessary to ask these countries to supply any missing or additional data. It is not the intention that the EUROWATERNET data flow should require countries to make duplicate supplies of data and so any data already submitted to the Marine Conventions need not be re-supplied through the EUROWATERNET process. These data will be requested directly from the Marine Conventions. The content and format of the data request is the same for both the Marine Conventions and individual countries.
Validation of Existing Data
By the end of November 2003, data on hazardous substances in biota, the physical characteristics of the monitoring stations and upstream catchment / basin pressure data will be visible on Reference WATERBASE. Countries are invited to download, examine and validate their national data previously supplied via Marine Conventions or direct to the EEA. Please provide any missing information as part of the 2003 update. All other transitional, coastal and marine water data collected under the EUROWATERNET process will be visible on the web by Spring 2004, including the latest year data. (Please note that disaggregated data supplied by the Marine Conventions will not be available for download from Reference WATERBASE).
2003 Data Requirements
The elements of data to be collected under the 2003 data flow cover the state (quality) of, and pressures, on Europe's transitional, coastal and marine waters. Quality determinands include those relating to nutrients, organic pollution indicators and hazardous substances.
This year we also request data on riverine input loads and direct discharges in order that detailed assessments may be made on the impact of loads and discharges to the marine environment.
The data sets required are detailed below:
Detailed descriptions of the contents of each data set are provided in the template file EWN_TCM_2003.xls and the EWN update guidance for transitional, coastal and marine waters, both of which can be downloaded from the EIONET Water Interest Group on CIRCLE.
Delivery of Data
Data files should be uploaded either to the Central Data Repository or to your national EIONET server, depending on the choice of your country for delivering EIONET priority data. All data files should be delivered in either Excel (.xls), tab delimited ASCII text (.txt) or Access database (.mdb) format. Please use the Excel templates as a guide to formatting your data.
Deadine for Delivery
We hope that this letter will be useful for you when organising a programme of work with your NRCs in order to deliver the required data flows by the deadline of:
Friday, 30 January 2004
