Coastal areas are configured as the meeting point and strong interconnection between land and see, as well as of natural and anthropic dynamics, upon which climate changes act synergistically and simultaneously. Therefore, these are areas that need to be continuously and constantly monitored.
The National Institute of Oceanography and Experimental Geophysics (OGS) of Trieste (Italy), Public research body in the field of Earth and Sea, developed a meteo-oceanographic buoy able to measure, in real time, the most important meteo-oceanographic parameters.
MAMBO buoy consists of a hull, an overhead support structure and a battery powered electrical system, to date charged by a solar panel.
In addition to the solar panel, the new version of the MAMBO, which is going to be put to sea in this month of August, will have a wind generator: the WindKinetic Polar 50W.
The supplement of the wind generator has been thought in order to increase the reliability of the whole system, to minimize the risk of lack of electric supply. The only solar system is, by definition, dependent on solar irradiation, therefore sensitive to seasons and night and day alternation.
For this reason, a wind system proves to be complementary to the solar system, because of its capability to offer more energy supply when most needed. In the marine operating context, it is crucial to use products and materials designed on purpose. The WindKinetic Polar 50W generator is in fact functional to the marine use: designed and produced to endure in bad operative conditions, it is able to supply 50W rated power and 100W maximum power. Furthermore, Polar 50W system does not require for maintenance and it is made up of special materials, such as aluminum alloy, AISI 316 steel, polyurea coatings.
The buoy is also equipped with sensors aimed to measure several physical quantities, such as pressure, temperature, saltiness, conductivity, oxygenation etc. along the water column.
A sensors system installed on the external trellis allow the measurement of meteorological parameters. Monitored data are transmitted every 3 hours to the station of the OGS headquarter.
MAMBO presents also a system, which has been developed by the Institute, that controls an ADPC (Acoustic Doppler Current Profiler) positioned on the sea bottom, next to the buoy, to study sea currents with real time data transmission.
