Abstract

The JRC has constructed and successfully tested a prototype oceanographic buoy capable of collecting meteo-oceanographic data, receiving acoustically transmitted data from the seafloor and from up to 50 m deep in the seabed, and transmitting the data every hour via satellite to the laboratory. A radio link allows commands to be sent from the laboratory to the buoy, and from there acoustically to the seabed, establishing a direct two-way link between the laboratory and the instrumentation in the seabed. This paper discusses the requirements, design, technological choices and tests of the sensors, interfaces, buoy controls and communications, radio and acoustic links. It is concluded from the preliminary tests and in-situ trials that the system functions successfully. The buoy body has proved useful as a platform for the experimental test phase. However, for long-term deployment in coastal waters or on the open ocean, it will need to be adapted according to specific site characteristics, such as climatic and wave conditions. The modular electronics and controls, antennae, sensors, navigation interfaces, radios, acoustic transponders and acoustic receivers, as well as the modular software, fulfil all the design requirements identified.
