SeaDataNet (2006 - 2011), funded by the EU as an FP6 Research Infrastructures project, is actively operating and further developing a Pan-European infrastructure for managing, indexing and providing access to ocean and marine data sets and data products, acquired from research cruises and other observational activities in European marine waters and global oceans. It is undertaken by the National Oceanographic Data Centres (NODCs), and marine information services of major research institutes, from 35 coastal states bordering the European seas, and also includes Satellite Data Centres, expert modelling centres and the Intergovernmental Oceanographic Commission (IOC) of UNESCO, International Council for the Exploration of the Sea (ICES) and EU Joint Research Centre (EU-JRC) in its network. http://seadatanet.maris2.nl/browse.asp
