The Australian Ocean Data Network (AODN) will enhance access to, and re-use of, Australian marine science data and data products, by ensuring standards-of-practice across the marine science data management community, and providing a one-stop-shop for marine science data access, using the foundation architecture and services of the Oceans Portal and MEST (Metadata Entry and Search Tool). The AODN offers a single, standards-based, distributed and federated marine science data network. It builds on existing collaborative relationships, agreements, and infrastructure including the existing “Virtual Hosting Repository”, which offers archiving, ready discovery and access, and delivery of marine science data from a wide range of funding schemes, and from organisations and individuals in both the government and higher education sector. Two projects of interest are BlueNet and the e-Marine Information Infrastructure Project (eMii). BlueNet is assisting Australian universities to link to the AODN through the development of software, outreach to partner universities and through collaboration with AODN agencies and other virtual repositories (e.g. OBIS). eMii is the data management component of the IMOS (Integrated Marine Observing System) program. Using an integrated standards-based approach across a range of marine science disciplines will, for the first time, drive a new generation of approaches to data management and sustainability.
