Marine Science: Dye Tracing (Rhodamine, Fluorescein) using Chelsea Fluorometers

Monitoring the dilution and movement of a tracer introduced into the water column provides an excellent means of determining the path that may be followed by a discharge and the rate at which dilution is likely to take place. Fluorescent dyes such as Rhodamine, Fluorescein or Agma are the most frequently used tracers for such investigations.  Chelsea Technologies has been providing dye tracing systems since 1982. 

 

Typical marine scinece applications include sub-sea pipeline leak detection, pollution studies, water flow analysis (ocean currents, cave water flows etc). Dye tracing operations are common in determining water retention and flow in newly commissioned or modified oil or gas sub-sea pipelines. CTG has had a number of year's experience supporting these activities.

 

The CTG systems can be configured for a wide variety of tracers, are highly sensitive, robust, and deliver real-time data. They can be moored, profiled, towed or affixed to ROVs, gliders or AUV platforms.
