Product Description

Applications

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.
.

  • Primarily used in the marine environment for biomass studies.

  • Whilst the abundance of individual bioluminescent species can be studied, it is often an indication of toxic algal blooms.

  • Primary production assessment

  • Designed to be moored or profiled (with pumped systems) or deployed in towed vehicles (AQUAshuttle, Nn-Shuttle, SeaSoar).

Features

  • Small, rugged

  • Low power consumption

  • High sensitivity

  • interface for flow sensor
