Leaders in environmental consulting @PLANCTON_ANDINO (Chile) have been using a @Chelsea_CTG  Act2 #frrf3 to monitor red tides as part of the Bivalve Molluscs Health Program.

Leading environmental consultants Plancton Andino SpA (Chile) are using a CTG FastAct Laboratory FRRf System to monitor red tides as part of the Bivalve Molluscs Health Program.

Chile is the world’s fourth largest producer of mussels and the health of the mussels is of paramount importance to the economy. These “red tides” or Harmful algal blooms (HABs) are natural events occurring around the world. Since first being reported in Chile in 1972 in the Strait of Magellan these HAB have increased in both frequency and geographic coverage.


Leading subsea technology developer Sonardyne International Ltd. has acquired maritime and marine science technology specialist Chelsea Technologies Group Ltd. The acquisition is part of a long-term growth strategy for Sonardyne, to diversify into markets where it sees an opportunity to build on its core technology base and expertise in underwater acoustic and optical communications, navigation and autonomous monitoring systems. In acquiring Chelsea (also known as CTG), Sonardyne will both strengthen its presence in the maritime, marine and ocean science sectors and create new opportunities in the water environmental, defence and process control markets. Chelsea will gain access to Sonardyne’s considerable research, production, testing, compliance and global distribution capabilities, allowing the company to access many more international territories.

Introducing new V-Lux Fluorometer

The Our Ocean Wealth Summit, takes place in Galway, Ireland as part of SeaFest 2018  on 28/29 June. A major part of the two-day programme is the Marine Ireland Trade Show which CTG are delighted to participate in.

CTG’s Managing Director, Dr Brian Phillips and Marine Sales Manager,  Sam Kirby will be showcasing the new V-Lux: Multi-parameter fluorometer configured to detect either Aromatic Hydrocarbons, Algae or Tryptophan-like fluorescence.

Marine Tech Expo Plymouth

CTG are delighted to be exhibiting at the 2nd Marine Tech Expo @Marine_Expo this week. The event brings together decision makers involved in the latest marine innovations in blue technology under one roof at the University of Plymouth, 21-22 June 2018.

CTG's Stephanie Lavelle will be demonstrating the FastBallast, a portable ballast water compliance monitor for use with discrete or flow-through samples.  CTG's Sam Kirby will be demonstrating the Act2-based FRRf laboratory system for measuring primary productivity and assessing the health of phytoplankton communities. We look forward to seeing you.


CTG Pipeline Leak Detection System chosen by ECA Group, France

ECA Group, France, leading providers of advanced unmanned and autonomous systems has chosen a CTG Pipeline Leak Detection System (PLD) to be employed in the role of subsea pipeline inspection and oil leakage detection. The 600 metre, certified system contains a CTG Uvilux configured for hydrocarbons. The PLD system will be integrated into ECA’s innovative ROV, the H800-SUR alongside a hydrophone, water sampler and sediment sampler.  Lets talk more - We are sponsoring the 4th Premiam Conference "Post Spill Monitoring, Looking Back and Moving Forward" on the 21st June at the Natural History Museum, London. We'll be showcasing our range of  hydrocarbon and oil monitoring products.

National Institute for Environmental Studies buys second FastOcean APD for algal studies in Japanese lakes After successful field studies with their first CTG FastOcean profiling system, acquired in early 2016, the National Institute for Environmental Studies (NIES) in Japan has just purchased their second FastOcean profiling system.

NIES have been using CTG Fast Repetition Rate fluorometers (FRRf) for a number of years to study photosynthesis in lakes around Japan as part of a long-term environmental monitoring program. The new profiling system is destined for their Lake Biwa branch, located in the Shiga prefecture in Japan, as part of a jointly funded program.

FastOcean used world-wide to monitor gross and net primary productivity (GPP and NPP)

Over the last year, Chelsea Technologies Group (CTG) has seen a number of publications appear regarding the use of the FastOcean Fast Repetition Rate fluorometer (FRRf) in the field. The FRRf is a great tool for measuring primary productivity and assessing the health of phytoplankton communities. The published papers (see below) demonstrate a wide range of uses for the instrument. These include investigating phytoplankton physiology in the Southern Ocean with regard to iron availability, comparing the effect of ocean acidification and irradiance on photophysiology in different phytoplankton groups and investigating the effect of silver nanoparticle toxicity in diatoms.
