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.
At present Envirtech manufacture two classes of devices: the Vulcan Class and the Poseidon Class (learn more).

Tsunami Warning System

Italian Data
Buoy Network

Envirtech deployed the 15th buoy of the  Italian Data Buoy Network, formerly known as "Rete Ondametrica Nazionale".
The new buoy has been moored off shore VENICE  (North East of ITALY in Adriatic Sea). 

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 ...

Venice Microwaves
Tide Station

It is fully operational the Envirtech microwaves 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.  More ...

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,  stock company based in Italy in 1999 to manufacture, deploy and maintain data acquisition networks on land, 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 ...

About us

VULCAN CLASS devices are sea bottom laboratories able to collect many parameters and can be tailored on request adding any kind of transducers.

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. 

Tsunami Bulletins: INDIAN OCEAN - PACIFIC OCEAN

October 16th, 2010 - SOA crew successfully deployed Envirtech "Poseidon Class" tsunameter. To learn more please contact info@envirtech.org or read more info about Poseidon Class Tsunameters.

IN BRIEF:

Max operational depth  6,000 meters, 1 mm H2O accuracy, 2 years power pack, spread spectrum acoustic communications, independent acoustic release, titanium vessels  and AISI 316 stainless steel frame, up to 4 Gb Data Logger.

Thailand: 
Tsunami   Warning  System

Bangkok July 2011 - NDWC has successfully completed the assessment of the new tsunami monitor systems deployed in the Andaman Sea during last December campaign. Two tsunami- buoys and two Poseidon Class tsunameters have completed the marine segment of the Thai Tsunami Warning System. The deployed systems are working properly and releasing data  on Web and  the new BUFR/CREX TM306027 format for GTS worldwide dissemination.

India:  NEW Calypso Tsunameter

Chennai January 2012 -  Acceptance test for the new Envirtech Calypso Class tsunameter  has been completed by the National  Institute of Ocean Technology (NIOT).  Calypso hosts all components in one Titanium cylinder. Standard operation depth is 6,000 meters and  the estimated power authonomy is 2.5 years. All Envirtech tsunameters embed the Mojfeld algorithm for Deep-ocean Assessment and Reporting of Tsunamis and bidirectional spread spectrum acoustic communications.

MKI-3  Envirtech DATA BUOY

Venezia -   Envirtech MKI-3 Data Buoy has been presented at Vega - Science Park. The buoy is state of the art in directional wave measurement and oceanographic data gathering. It includes a solid-state MEMS directional wave measurement pack, an automatic weather station and a sea surface temperature transducer. The payload can be expanded with further underwater instrumentation to measure biochemical and physical parameters, and a multi-satellite, multi-channel receiver for iSSH measurement (tide). The buoy is composed of a central metal pole in AISI 316 stainless steel, and three rotationally moulded, foam-filled floats that are assembled to form the shape of a truncated cone. The buoy dimensions, the focal light height, and the radar corner reflector
allow good visibility in any conditions, day or night.
