New Portable Echo Repeater System
Chelsea Technologies Group (CTG) won a tender from an American company for a portable echo repeater system, with a further system going to Singapore next year.
This new system is a miniature version of CTG’s flagship towed sonar test and evaluation system, VASS (Versatile Acoustic Source System). A new low frequency hand-deployable acoustic transducer will be employed along with a portable PC for operation from small vessels. It includes much of the functionality of the larger VASS system and now operates down to 300Hz whilst maintaining its portable advantage.
The system is controlled by an easy-to-use Graphical User Interface commanding the Digital Signal Processor which is used to Echo Repeat, Transpond, and produce Calibrated transmissions with up to 24 Tones simultaneously.
It provides a highly versatile and flexible sonar test system that is configured by simple mouse or keyboard selections. In addition to instant configuration changes, it allows desktop set-up of complete trials programs in advance hence avoiding costly errors in signal definition during calibration trials.
Existing users of the VASS & PERS systems include QinetiQ, the UK Director of Submarines, NATO SACLANT Undersea Research Centre, La Spezia, Italy and the Belgian Navy.

CEESCOPE Survey Program Commenced at Mississippi River Grain Terminal
Grain from US farming is transported down the Mississippi River in enormous quantities for export to customers all around the world. The grain barges that have been transported downriver are unloaded at grain elevators and rapidly transferred to cargo vessels alongside the docks. Ships are continuously arriving to collect their grain cargo and safe operation of the terminal relies on having enough water at the dock to accommodate the vessels. The Mississippi River is a huge river with a high sediment content and...

Ultrasonic impact on algae and other Aquatic Life Forms
A Technical Explanation The Hydro BioScience® Quattro-DB® and Mezzo-DB™ devices emit ultrasonic frequencies (i.e. above human hearing capability) that cause simply constructed forms of algae to vibrate at their natural frequency. Matching that frequency causes critical structural resonance to occur, much like playing the natural frequency of a crystal glass back to the glass that will cause it to vibrate violently and eventually break the glass by fatigue. Some types of algae that have complex...

SPARUS II AUV proves to be a very good option for equipment integration
National Oceanography Centre (NOC) is the United Kingdom’s centre of excellence for oceanographic sciences. Back in 2018, NOC team chose IQUA’s SPARUS II platform to become a test bed for new developments that may be later transferred to other vehicles in their fleet. The team picked this AUV for its versatility, its ROS driven software and its possibilities for sensors integration. In this case, NOC team has closely worked with Sonardyne, a global provider of underwater acoustic, inertial, optical...
