Our Products

Cyprus Subsea develops products that add value to autonomous observing systems through increased capabilities and lower costs.


Smart Interoperable Real-time Maritime Assembly (SIRMA™)

The Smart Interoperable Real-time Maritime Assembly (SIRMA™) is a re-programmable cable assembly connecting a marine sensor to a platform. Designed to reduce the costs of adopting marine autonomous systems, SIRMA™ simplifies the integration of a new sensor with a platform.

Developed through the RIF-funded SMART Cable Project, SIRMA™ consists of a low-power modular printed circuit board embedded between two cable connectors. This cable assembly allows several functionalities – from data processing to data logging to voltage regulation between a sensor and a platform such as a glider, AUV, or buoy. SIRMA™ turns any cable assembly from a passive device into a smart processing unit.


Ocean Acoustics Payloads

Ocean acoustics is the study of sound and its behavior in the sea. When underwater objects vibrate, they create sound pressure waves that alternately compress and decompress the water molecules as the sound wave travels through the sea. Sound waves radiate in all directions away from the source. The compressions and decompressions associated with sound waves are detected as changes in pressure using man-made sound receptors such as a hydrophone, or underwater microphone. A scientific echosounder uses sonar technology for the measurement of underwater physical and biological components. The sonar and electronics record the time interval between emission and return of a pulse.

Cyprus Subsea developed ocean acoustic monitoring and detection systems integrated onto autonomous ocean platforms such as underwater gliders and buoys.

A scientific echosounder such as the Kongsberg SIMRAD EK80 WBT-mini pictured below uses active sonar technology for the detection and characterization of underwater physical and biological components present in the water column. The sonar and electronics record the time interval between emission and return of a reflected pulse. They provide information on the density of particles, their characteristics, and distribution.

Cyprus Subsea develops both passive and active ocean acoustic monitoring and detection payloads — integrated them with autonomous ocean platforms such as underwater gliders and buoys. Most importantly, these payloads drastically increase the ability to monitor the ocean while also keeping costs low.


DeepEcho Module

DeepEcho Echosounder and Transducer

The DeepEcho Module is the first scientific wide-band echosounder – deployable to a depth of 1000 meters – successfully integrated onto an ocean glider.

Cyprus Subsea redesigned the compact version of SIMRAD EK80 wideband transceiver (WBT) echosounder in order to fit into the payload bay of a Seaglider. As a result, the reconfigured WBT electronics fit into a cylindrical aluminum pressure housing. Our design includes a 333 kHz or 200 kHz single-beam transducer.


gListen Board

gListen Board

The gListen Board is an Ethernet to RS-232 converter with voltage regulation and onboard memory for downloading data.

Paired with an OceanSonics icListen digital hydrophone, the gListen board keeps track of events detected by the hydrophone. At the end of each dive, the board reports the detected events via satellite.

The board facilitates near real-time event detection and spectrum retrieval. In addition, user-configured frequency spectra can be transmitted.


Passive Acoustic Monitoring (PAM) Buoy

A Passive Acoustic Monitoring (PAM) Buoy offers real-time acoustic monitoring with a digital hydrophone, environmental data buoy and GSM Bridge.

When deployed in the ocean, the PAM Buoy captures sounds from the surrounding environment & facilitates real-time acoustic data transmission.

Cyprus Subsea has integrated a digital hydrophone with a GSM bridge to provide users with real time connection to their hydrophone providing both an acoustic stream and detected events.
