Many regions including Europe, the USA, Australia and Canada are making significant progress in facilitating the discovery, access and long-term stewardship of marine data through the development, implementation and operation of national, regional or international distributed ocean observing and data management infrastructures such as SeaDataNet, EMODnet, IOOS, R2R, and IMOS. The Ocean Data Interoperability Platform (ODIP) project, supported by the EU Framework Programme 7 (FP7), National Science Foundation (USA) and Australian government, was initiated 1st October 2012 and continues as ODIP II for another 3 years with EU HORIZON 2020 funding. ODIP includes many of the major organizations engaged in ocean data management in Europe, US, Australia and Canada. ODIP is also supported by the IOC-IODE, closely linking this activity with its Ocean Data Portal (ODP) and Ocean Data Standards Best Practices (ODSBP) projects.
