WaLTER provides via its dataportal access to archived monitoring data of the Wadden Sea. For its infrastructure to achieve this it amkes use of SeaDataNet standards and software. SeaDataNet is the Pan-European infrastructure for marine and ocean data management and delivery services. It is supported by the EU under its Research Infrastructures programme. It connects 40 National Oceanographic Data Centres (NODC's) and 60 other data centres from 35 countries, bordering the European seas and Atlantic Ocean. The centres are mostly part of major marine management and research organisations that are acquiring and managing a large collection of marine and ocean data from various disciplines. The Common Data Index (CDI) data discovery & access service provides harmonised access to the large volumes of datasets that are managed by the connected data centres. The CDI service contains already references and gives access to more than 2 milllion marine and oceanographic datasets as managed by 100 data centres. These numbers are increasing regularly because of further data population and more connected data centres as part of SeaDataNet II, EMODnet and other EU projects. For inclusion in the WaLTER INSPIRE compliant CSW service, the CDI records (at granule level) have been aggregated into CDI collections by a combination of Discipline, Data Centre, and geometric type. Each CSW XML record therefore represents a large collection of individual metadata records and associated datasets. By following the specified URL to the WaLTER portal users can evaluate these metadata in detail and request access by downloading of interesting datasets via the shopping cart transaction system that is integrated in the WaLTER portal.
