netH2O: Calafuria-GlobalService


This netH2O personal smart buoy, sponsored by Global Service srl from Livorno for Associazione Costiera di Calafuria, is positioned on a water depth of approximately 11m. The location is close to "Grotta del Grongo", one of the most famous diving spots in the "Magic mile" south of Livorno.

This buoy is equipped with several accessories, including webcam, solar panels, and a floating component and mooring system which can be used also for the mooring of diving boats.

The site is ideally located for the positioning of a scientific buoy, which can also mitigate the environmental pressure from recreational diving activities.

Global Service srl, sponsor of the initiative, asked Elements Works to design, build and install a complete system based on the netH2O, which then was made available for free to Associazione Costiera di Calafuria to conduct scientific activities.

To preserve the seafloor, Elements Works has used for this netH2O a mooring based on immersed tensioned buoys (jumpers). This system avoids completely the problem of abrasion of the sea floor from mooring lines. The jumpers, placed at 5m depth, can also be used by divers for a stop during their ascent.

This netH2O can measure the water temperature and estimate direction and intensity of currents and waves. An underwater module, linked to the surface one by cable, is equipped with a webcam which transmits its "feed" via the internet. Elements Works is responsible for collecting the data and making it available to ISPRA, to Associazione Costiera di Calafuria and to Global Service itself.

Diving Centers, which can freely use the buoy for mooring, are involved in the cleaning of the sensors and in the monitoring on the mooring lines. The promoters of the initiative want to involve also schools in it, to increment the knowledge and the safeguarding of the territory by the population, in the spirit of "Citizen Science"
