Communications, data and information exchange are the key elements of the operational ocean monitoring and forecasting networks, defined in the Global Ocean Observing System (GOOS). Development of observing and closely related operational forecasting system in the Black Sea region requires the exchange of significant data and information volumes. ASCABOS is designed to strengthen the communication system ensuring flexible and operative infrastructure for data and information exchange between partners and end users. ASCABOS aims to increase public awareness and to stimulate and motivate the utilization of operational oceanographic information in management and decision-making practices. In the same time, high level of the operational services must be built and retained. ASCABOS will support achievement of these crucial objectives by initiating an educational and training programme designed for young scientists and wide spectrum of end users. Considerable work has been performed on compiling meta-databases on the Black Sea environmental data, information and research within previous international initiatives and projects. To support and to strengthen the exchange between scientists, governmental managers and other users ASCABOS is planning to combine experiences and instruments in order to develop a Black Sea information system, containing all available metadata, validated and efficiently updated through the Internet. ASCABOS plans to organize and realize a cost-effective VOS pilot programme, applying modern technologies and developments for data collection, transmission, storage, use and dissemination. The VOS programme will provide data for model assimilation and respond to the GOOS demand for long-term monitoring of the marine ecosystems.
