We designed effective, high reliability Tsunami Warning System starting registered tsunami after the Stromboli Volcano eruption in December 2002. The system has been based on multisensor (both seismic wide spectrum, and pressure gauges) deep ocean platforms.
Envirtech deployed the 15th buoy of the Italian Data Buoy Network, formerly known as "Rete Ondametrica Nazionale".
Vulcan Class are built around a broadband Ocean Bottom Seismometer. To assure the best coupling between sea bottom and the seismometer has been developed a special release mechanism. All the units are hosted in Titanium vessels. A special CPU, based on Arm technology, has been developed to reduce power consumption to assure at least 2 years authonomy. High rate sea bottom collected data are transmitted to the surface buoy using an inductive modem coupled to the mooring line. MORE ...
It is fully operational the Envirtech radar tide station installed next the Malamocco gate to the Venice laguna. The station collects 12 samples/min of tide level with no stilling well. Gathered data can be used to evaluate any kind of low frequency sea motion inside the laguna and are published on internet each hour. A couple of meteorological stations complete the settlement.

POSEIDON CLASS devices are ocean bottom devices able to collect very high accuracy and stable pressure data. At present the maximum operative depth is 6,000 meters. Collected data are transmitted in real time to a surface "SPAR" buoy via spread spectrum acoustic modem. The surface buoy relay received data to a control center via satellite.
We are a private, European, company based in Italy since year 2009 to manufacture, deploy and maintain data acquisition networks on sea surface and sea bottom. We also provide engineering, projects, systems, ideas, information, software and solutions for global environmental problems. As global technological partner we assist large companies and Governments to develop the best environment oriented solutions. Whatever is your geographic scale project we can solve it developing a tailored solution based on our worldwide recognized experience. More ...
VULCAN CLASS devices are sea bottom laboratories able to collect many parameters and can be tailored on request adding any kind of transducers.
Please see video clips about the buoys deployments. The new Data Buoy Network, owned by ISPRA, the Institute for Environmental Protection and Research consists of 15 oceanographic buoys deployed along italian shores. The buoys collect directional sea motion data, sea surface temperature, wind speed and direction, air pressure and humidity. Gathered data will be available on WMO GTS, via WEB and on the Italian teletext service (RAI-1) . More ...
SPAR BUOYS - Are tall, thin buoys that float upright in the water and are characterized by a small water plane area and a large mass. Because they tend to be stable ocean platforms, spar buoys are popular for making oceanographic measurements. In Envirtech ocean data acquisition systems, SPAR BUOYS are used to collect data from seabottom and to relay them using satellites, like Inmarsat, GOES, Iridium and so on.

Maritime Domain Awareness, MDA, is the effective understanding of anything associated with the Maritime domain that could impact the security, safety, economy, or environment. This is the definition in the USA - National Plan To Achieve Maritime Domain Awareness. There exists limited awareness and effective understanding of vessels that do not emit electromagnetic signals and for emitting targets, it is difficult to correlate transmitted data with actual target behavior. Decision-making authorities require information necessary to identify and react to potential threats to national security arising in the maritime domain. Threats must be identified as early and as far off-shore as possible, requiring awareness of coastal waters out to the Exclusive Economic Zone and even on the high seas.The Envirtech MK-VI Surveillance buoy consents to extend awareness about the marine environment beyond the horizon. As first goal the buoys detects, identifies and tracks cooperative maritime targets, equipped with active AIS and radar transmitter, relaying collected data to an on-shore control centre via LEO Satellite communication systems. Some additional payloads can also detect and track non-cooperative targets using passive sonar and radio interferometer.The buoy has been designed to operate as fixed (moored) node in large networks, to be deployed for long time in deep sea and to reduce maintenance interventions. Further modular and exchangeable payloads allow the buoy to collect meteorological, oceanographic and water quality data, including pollution agents. Flexible solar panels and an emergency lithium power pack assure needed power in any condition. Reduced dimensions and technical solutions adopted in hull design consent to reach high survival ratio to sea storms (cyclones) and collisions.
