Geonica WaveAlert - Wave measuring system
The WaveAlert System has been designed by GEONICA for sea waves and currents monitoring in sea ports and coastal areas in different applications, be it for coastal oceanographic studies or for providing information on the sea conditions to building companies during the construction of ports, docks, piers, etc., as well as to major oil or liquefied gas tankers, in order to contribute to their safety during the dangerous
unloading works.
Sea waves measurement is carried out using buoys provided with the appropriate measurement instrumentation, as well as equipment transmitting data to a Computer on land, be it via GPRS cellular telephony or radio link.
Another sea waves measurement technique consists in using an ADCP (Acoustic Doppler Current Profiler)-type transducer anchored at a distance from the coast and connected, via a sunken cable, to an electronic unit on land. Said transducer, using a complex process of the Doppler signal received from the oscillating sea surface, is capable of measuring the directional waves from the bottom of the sea (usually located at depths of up to 40-50 meters or above), but with the advantage of offering as well, and simultaneously, the profile of the sea currents, from the bottom of the sea to its surface.
