| Product Description | |
|
GLOWtracka’s precision flow meter stimulates bioluminescent organisms – principally dinoflagellates. The instrument then measures the light flashes as the organisms pass the detector. The complete range of flashes that can occur – from single events to mesoscale – is measured. The measurements indicate changes in primary productivity in an area, giving the instrument a useful role in pollution monitoring and biomass studies. Since the abundance of individual bioluminescent species can be studied, it is often an indication of toxic algal blooms. GLOWtracka
is designed to be moored, profiled (with pumped systems) or deployed in
towed vehicles. |
