| Abstract | Administration and dimensions,Chemical oceanography,Cross-discipline,Environment Abstract EMODNET is a pilot component for a final operational European Marine Observation and Data Network, launched by the Directorate-General for Maritime Affairs and Fisheries (DG MARE). EMODNET aims to assemble fragmented and inaccessible marine data into interoperable, continuous and publicly available data streams for complete maritime basins. The specific objectives of the pilot action are to: collate existing data from public and private organisations and process them into interoperable formats; assessing their accuracy and precision; develop, test, operate and maintain a portal allowing public access and viewing of these data and products; monitor and report on the effectiveness of the system in meeting the users needs; analyse the necessary requirements to maintain the components built up in each lot as a sustainable infrastructure. EMODNET Chemistry is focused on the groups of chemicals required for monitoring the Marine Strategy Directive: synthetic compounds (i.e. pesticides, antifoulants, pharmaceuticals), heavy metals, radionuclides, fertilisers and other nitrogen- and phosphorus-rich substances, organic matter (e.g. from sewers or mariculture), hydrocarbons including oil pollution. It concerns the Greater North Sea, including the Kattegat, and the English Channel, the Black Sea and five spots in the Mediterranean (Balearic Sea, Gulf of Lion, North Adriatic Sea, Gulf of Athens and NE Levantine basin). EMODNET Chemistry is based on SeaDataNet network of NODC’s, which oversee data collection for the requested geographic areas, will run and further develop SeaDataNet infrastructure, which provides a unified and transparent overview of metadata and a controlled access to large data collection, in combination with other multidisciplinary data sets. Specific expertise will coordinate data analyses and validation, and the creation of data products. |
