RIASSUNTO
The Bulgarian National Operational Marine Observing System (NOMOS) is a system of systems designed to allow the real-time assessment of weather and marine conditions in the coastal, shelf and open sea areas of the western part of Black Sea. NOMOS consists of several subsystems: POMOS, Galata, Shkorpilovtci, BulSeaL and BulARGO. POMOS is an observing system located in the ports (14 measuring sites, 45 instruments, 14 weather and seastate parameters), designed to provide weather and sea state operational information for the areas of major Bulgarian ports (Varna, Burgas and Balchik), intended to secure safety shipping in ports, canals and bays. Galata is a platform which provides open sea Real-time meteorological and oceanographic information from 24 sensors, measuring 31 major oceanographic and meteorological parameters. Shkorpilovtci is a coastal oceanographic station compiling: weather station, sea level gauge, UV radiation sensor and Recording Doppler Current Profiler with wave sensor. BulSeaL is a network of sea level stations including four historical sites, measuring sea level from more than 80 years. BulARGO is a set of Argo floats deployed in the frame if the project supported by Bulgarian National Science Fund, Ministry of education, youth and science. The purpose of the BulARGO project is to develop a new national marine research infrastructure for in situ observation in Black Sea based on autonomous profiling floats as a Bulgarian component of the Euro Argo network. These subsystems collect real time data using various instruments and sensors placed at different strategic locations. All instruments are connected to communication system via intranet which provides direct access to the sensors. The measured data are transmitted to the central collecting system, where the information is processed and stored in database. Access to database is through internet/intranet with the help of browsers. Actual data is controlled by Data Management System an can be displayed on the computer screens using report server supporting thereby needs of different group of users. Next future development will be to install new system which includes five open sea moorings equipped with meteorological and oceanographic sensors as well as with seismometers as a main component of a marine hazards early warning system. The main goal of NOMOS is to support sustainable development of the Bulgarian Black Sea coast and EEZ, and the main task is to provide operational information for the needs of: national security, civil protection, Search and Rescue, government and local authorities, port authorities, shipping, marine industry, fishery and aquaculture, tourist industry, environmental protection, coast protection, oil spills combat and other interested. NOMOS real time data is one of the most important sources of multi-parameter operational information in the Black Sea which will serve for monitoring, verification and improvement of model results and forecasts as well as for collecting long time series of data needed for climatic research, marine physics, chemistry and biology. Free real time data access and developed user friendly WEB and WAP interfaces made the system useful not only for science, marine industry and governmental agencies but also for general public, especially for yachtsmen and windsurfers.
