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 designed 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. Two 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 established 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.

ENVIRTECH MKIV: 3 Metre Buoy
The MKIV compliants the raising requirements for rugged sea surface platforms able to host biochemical/physical payloads.
All data provided by sensors are stored using a compact flash NVRAM with capacity up to 32 Gb. The MKIV CPU can acquire data from up to 20 async interfaces. All the electronic units are protected inside a waterproof case. It is available a wide choice of telemetry systems, like UHF/VHF, Inmarsat, Orbcomm, Iridium GSM, etc.- The turret and the floats can be disassembled to facilitate the transport of the buoy: the turret can be split into two parts and the float can be divided into three segments.
ENVIRTECH WAVE SENSOR
It is a state of the art IMU (Inertial Measurement Unit) . It measures the buoy hull dynamic parameters using a combination of 3D accelerometers, gyroscopes, and magnetometers. A Digital Signal Processor (DSP) provides real-time 3D orientation, acceleration, rate of turn and earthmagnetic field data. Once calculated the attitude and heading data, a microprocessor unit processes them to obtain a geographically oriented displacement file (HNE file). Learn more.
