MK-I MAWS, Directional Wave Buoy
The DeepSea MKI buoy is state of the art in directional wave measurement and oceanographic data gathering. The buoy 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). Composed of a central metal pole in AISI 316 stainless steel, the buoy dimensions, the focal light height, and the radar corner reflector allow good visibility in any conditions, day or night.

MK-IV 3Metres Oceanographic Data Buoy
The Envirtech MKIV, 3-Metres buoy, is state of the art in met-ocean data gathering. In standard configuration it includes a solid-state MEMS directional wave measurement pack, an automatic weather station (AWS)and a sea surface temperature transducer. Payloads can be expanded with further instrumentation to measure bio-chemical and physical parameters, like multi-parameter probes, ADCPs, multi-satellite, multi-channel receiver for iSSH measurement (tide). The buoy dimensions, the focal light height and the radar corner reflector allow good visibility in any conditions, day or night. The buoy is the ideal solution for permanent floating laboratories.

MK-III Tsunami Buoy
Envirtech MKIII Data 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 the sea bottom and to relay this data using satellites, such as Inmarsat or Iridium, to a control center on shore. The buoy assures a very stable platform for bidirectional communications to/ from the ocean bottom, and allows total remote control of deployed devices. Together with an Envirtech Tsunameter the MKIII is a reliable part of any marine tsunami warning system.

MKI-4 Easy To Deploy (Etd)Tsunami Buoy
Envirtech Mki-4 Buoy Assures A Stable Platform For Bidirectional Communications To/ From The Ocean Bottom, And Allows Total Remote Control Of Deployed Devices. Together Underwater Modules, Like Calypso Or Poseidon Class Devices, The Mki-4 Is A Reliable Part Of The Marine Segment Of A Tsunami Warning System. It Can Be Deployed Easily Using Relative Small Fishing Boats Or Oceanographic And Supply Vessels And Can Be Serviced On Board Avoiding The Return In Port For Maintenance Operations. The Mki-4 Can Be Ordered In Two Configurations With Solar Panels Or Powered By Lithium Batteries.

MKVI Surveillance buoy and multistatic sonar node
The Envirtech MKVI buoy consents to extend awareness about the marine environment beyond the horizon. As first goal the buoy detects, identifies and tracks cooperative maritime targets, equipped with active AIS and radar transmitter, relaying collected data to an onshore control center via LEO Satellite communication systems. Some additional payloads can also detect and track non-cooperative targets using passive and active sonar (Multistatic sonar) and radio interferometer. The buoy has been designed to operate as fixed (moored) node in large networks, to be deployed for long time operation 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.
