Water quality profiling and monitoring


WES has played an integral part in many studies involving investigations into the environmental impact of human activity. A common requirement is to measure water quality parameters such as temperature, salinity and suspended sediment concentrations to assess the dispersion characteristics of the dredged material for example.

The instrument illustrated above is a specially adapted Space Technology Systems (NBA) 'Rapid Drop Profiler'. Used in conjunction with our in-house software, it presents and logs real-time through-depth profiles of turbidity and CTD.


Its unique integral 3-channel 'CB' water sampling array also enables water samples to be collected at discreet levels for calibration purposes.
