The role of EMODnet Chemistry in the European challenge for Good Environmental Status

Abstract. The European Union set the ambitious objective to reach within 2020 the goal of Good Environmental Status. The European Commission (2008) represents the legislative framework that drives member state efforts to reach it. The Integrated Maritime Policy supported the need to provide a European knowledge base able to drive sustainable development by launching in 2009 a new European Marine Observation and Data Network (EMODnet). Through a stepwise approach, EMODnet Chemistry aims to provide high-quality marine environmental data and related products at the scale of regions and sub-regions defined by the Marine Strategy Framework Directive. The chemistry lot takes advantage and further develops the SeaDataNet pan-European infrastructure and the distributed approach, linking together a network of more than 100 National Oceanographic Data Centres providing data from more than 500 data originators. The close interaction with EEA, RSCs, ICES and EMODnet–MSFD coordination group facilitated the identification of the most appropriate set of information required for the MSFD process. EMODnet Chemistry provides aggregated and validated regional data collections for nutrients, dissolved gasses, chlorophyll, and contaminants, properly visualized with OGC WMS and WPS viewing services. Concentration maps with 10-year moving window from 1960 to 2014, by season and for selected vertical layers, are computed and made available.
