Monitoring of Algal Production / Monitoring of Algae Growth - Monitoring & Testing

Over the past 20 years active fluorescence has been widely adopted by the scientific community, ecosystem managers and crop growers as a rapid and non-invasive method of estimating photosynthetic performance within a wide range of organisms, including phytoplankton (microalgae and cyanobacteria), biofilms, benthic autotrophs (corals, macroalgae and sea grasses) and terrestrial plants. The main rational for applying active fluorescence is that changes in key fluorescence parameters can reveal the early onset of chronic and acute degradation of photosynthetic performance and subsequent growth, e.g. resulting from nutrient deficiency or the presence on one or more toxicants.

Over the past 15 years we have been developing an active fluorescence technique called Fast Repetition Rate (FRR) fluorometry to monitor algae populations in the open-ocean, primarily to support climate and ocean modelling.
