Professor Andrew McMinn and his team from the Institute for Marine and Antarctic Studies, University of Tasmania have been using a Chelsea FastOcean Fast Repetition Rate fluorometer (FRRf) to gain an insight into primary production, photosynthesis and photosynthetic health in the Southern Ocean and Antarctic. His most recent deployments unearthed some new and interesting results relating to the physiological adaptations of Antarctic phytoplankton surviving in almost complete darkness under the E Antarctic sea ice. 

"Chelsea's hydrophone arrays are being used by the Institute of Marine Research in Bergen to study the reactions of fish to sound," reports Chelsea’s acoustics specialist Paul Bolton.  “Three custom designed, 8m long, active hydrophone arrays are now being used to map the sound field inside a fish pen at Austevoll, just south of  Bergen.    The reactions of a school of herring (ca. 10000 fish) to waterborne acoustic signals and noise of various types is currently being studied to get a better understanding of the environmental impact human-made noise can have on fish."

Ballast water is critical to the safe operation of ocean-going vessels. However, during ballast water exchange, thousands of aquatic organisms can stowaway and be transported from one part of the world to another. The transfer of these organisms in ships' ballast water can have devastating effects on the marine environment.  Chelsea has been working closely with both manufacturers of ballast water treatment systems and the certification authorities responsible for the formulation of testing criteria, to develop sensors capable of operating at the IMO level of compliance.

The Institute of Oceanology Chinese Academy of Sciences (IOCAS ), Qingdao, has just taken delivery of a Chelsea SeaSoar towed oceanographic system. The sale has been facilitated through Chelsea’s agents China ORES Co Ltd. The SeaSoar system is to be on permanent deployment from IOCAS's new Research Vessel, the Kexue Hao.

Chelsea Technologies Group is pleased to announce today the sale of another Echo Repeater Acoustics Source (ERAS) system for export. "ERAS is a compact and versatile acoustic system for the performance evaluation of a wide range of active and passive sonars," said Chelsea's Marketing Director, Richard Burt. "It will be used by the customer as a hand held, portable system from small vessels in remote locations.  ERAS is extremely attractive to users due to its relative low cost, small size and light weight. Systems are operating with customers in Europe, USA and Asia,”

"Chelsea Technologies Group has completed delivery of a further Sonar 2115 oceanographic sensor system, for HMS AUDACIOUS the fourth Royal Navy Astute class submarine," reports Richard Burt, Chelsea's Marketing Director. This follows on the successful delivery of systems for HMS ASTUTE, HMS AMBUSH and HMS ARTFUL. A separate system has also been installed at the Shore Based Integration Facility.  

 When most people think of warships, they think big guns, missiles and helicopters. But for hydrographic vessels the most important systems they carry aren’t necessarily their weapons, but their state-of-the-art underwater survey suites. Four SeaSoar undulating oceanographic recorders (UORs) are currently in use on the Royal Navy’s survey vessels, HMS ECHO and HMS ENTERPRISE. These UORs are towed behind the ships and collect a vast range of information using highly advanced oceanographic sensors. 

Sensors and electronics, provided by Chelsea have just been installed onboard RV Callista, the University of Southampton’s research vessel,  as part of the Technology Strategy Board co-funded WaveSentry project and are now collecting real-time wave data. Wave data is logged against the GPS position of the boat and will be merged with numerous other data streams by HR Wallingford, to enable more accurate 'nowcasting' and forecasting of sea conditions.  

Unique System FZE, one of the world’s leading integrated turnkey subsea and offshore solution providers has been appointed representative for Chelsea's products in the UAE. 

Chelsea Technologies Group are delighted to be holding two free, one-hour sessions on board the Research Vessel Callista plus an FRRf classroom session during Ocean Business. These events are designed to give delegates an opportunity not only to see first-hand the next generation coastal and oceanographic monitoring sensors, but also to ‘road test’ them.  To book your place on one of these FREE in-water demonstrations or arrange a meeting on Stand No: T8, please contact Ellen Keegan.

Chelsea' Justin Dunning presented at the Effluent Treatment Seminar at Sustainability Live, NEC Birmingham (18 April 2013). Justin's presentation focussed on recent academic work on the use of UV fluorescence to analysis effluent within water systems. He outlined the work Chelsea has been doing using this technology for real-time monitoring of effluent.

CTG is delighted to be participating in The UK Integrated Marine Observing Network (UK-IMON) workshop hosted by PML on 27-28 November 2012. The aim of the UK-IMON  initiative is to ensure that a national marine observatory is in place to improve the evidence base for future assessments of environmental status, using the most cost-effective technologies available to the UK marine science community. The group will be exploring adding value to existing key monitoring sites.
