Harmful algal blooms (HABs), occur when colonies of algae—simple plants that live in the sea and freshwater—grow out of control while producing toxic or harmful effects on people, fish, shellfish, marine mammals, and birds. The human illnesses caused by HABs, though rare, can be debilitating or even fatal. HABs have been reported around the world, and their occurrence is on the rise. HABs are a national concern because they affect not only the health of people and marine ecosystems, but also the 'health' of local and regional economies. A deadly algal bloom hit the world’s second biggest salmon exporter, Chile in 2016, which resulted in the death of nearly 23 million fish and the economic impact from lost production was roughly $800m. Continuous monitoring is key to early detection of harmful algal blooms.
CTG has a range of algae monitoring systems to choose from including:
FastOcean APD System: Fast Repetition Rate (FRR) fluorometry provides a non-intrusive and non-destructive method for probing photosynthesis by phytoplankton.
Act2-based laboratory and FerryBox systems: Act2 & the FastOcean FRR fluorometer can be combined to produce a highly automated system for probing oxygenic photosynthesis by phytoplankton.
The ALGAE-Wader & Pro provides real-time display of key Chlorophyll parameters necessary for water quality monitoring. As well as being very sensitive, these fluorometer sensors are optimised to provide low noise results.
