Ocean Science

Chelsea Technologies’ range of sensors & systems are used in a variety of ocean science applications including algal health monitoring, oil spill detection, sewage contamination monitoring, primary productivity assessment & climate change studies. These high precision sensors are robust and easily integrated into oceanographic platforms such as CTDs, Ferryboxes and moorings.

Our range of algal sensors are being used for the detection and quantification of chlorophyll a, phycocyanin and phycoerythrin. Lightweight & compact the TriLux & UniLux are perfect tools for oceanographic surveys, dye tracing studies, continuous monitoring and algal class differentiation. The FastOcean range of active fluorometers uses specialist Fast Repetition Rate fluorometry to analyse the efficiency of photosynthesis in algae and is used to estimate Gross Primary Production.

Chelsea solutions

­­­­­­­­­­­­­­­Chelsea Technologies range of optical sensors have been specifically designed to be low-cost, compact, lightweight and robust to be utilised with various sensor platforms. Analogue and RS232 communications are provided as standard for ease of integration.

The TriLux sensor is particularly useful as it combines three parameters into one small, low-cost sensor for monitoring chlorophyll a and a choice of turbidity, phycocyanin or phycoerythrin. The low cost makes them suitable for large scale monitoring programs, whilst their compact and lightweight design allows them to be easily integrated into platforms such as AUV’s and gliders.

The VLux MiniSonde  is a multi-parameter sensor providing robust data collection for either UV or visible fluorescence monitoring. The miniature, high quality MiniSonde provides integrated corrections for multiple environmental parameters, with models suitable for monitoring: BTEX, PAH, Tryptophan and Algae.

The established Chelsea FastOcean active fluorometer is the only commercially available multi-wavelength Single Turnover Active Fluorometer (STAF) system for in situ assessment of Phytoplankton Primary Productivity (PhytoPP). Over recent years, the STAF method incorporated within the APD system has increasingly been accepted as a practical alternative to 14C-based measurement of carbon fixation. When not profiling, the FastOcean sensors can be combined with Act2 systems to run fully automated FLCs in the lab.
