TriLux is a low cost, miniature algae sensor that monitors three key algal parameters in a single highly sensitive probe. The 3-in-1 fluorometer enables widespread monitoring in a variety of applications, including harmful algal blooms, aquaculture, water treatment works, river catchments and coastal studies.

With three different parameter combinations and depth ratings to 2000m, TriLux is suitable for a wide variety of water environments:

  • Chlorophyll a, Phycocyanin, Turbidity for freshwater deployments
  • Chlorophyll a, Phycoerythrin, Phycocyanin for coastal deployments
  • Chlorophyll a, Phycoerythrin, Turbidity for marine deployments

TriLux is compact and easy to integrate in wider systems and platforms including CTDs, data buoys, monitoring stations, AUVs and gliders. Adding the Hawk or Watchkeeper accessories allows real-time data display and logging with portable or wall mounted systems.

Questions & Answers
What is blue green algae?
Blue green algae (BGA) is not actually algae, but it looks like it. In fact it’s many tiny bacteria that can’t be seen with the naked eye. When the bacteria group together, they form large clumps, which look very much like floating algae. BGA can take many forms. It’s most recognizable as a shimmering blue-green layer on the surface of the water. At its peak, it can create a much more obvious scum. It can also appear as green streaks on the surface and as tiny green specks within the water. Sometimes it makes the water look a different color. It usually occurs in still waters where there isn’t much flow, such as reservoirs and quieter canals. You might also see it when there hasn’t been any rain for a while.

Lake Malawi: A Treasure to Protect

Lake Malawi (also known as Lake Nyasa and Lake Niassa) doubles as a Rift Valley Lake and one of the seven African Great Lakes. Due to its unique biodiversity, it’s a great place to conduct limnological studies. Harvey Bootsma is a professor for the School of Freshwater Sciences at the University of Wisconsin-Milwaukee and has had an interest in limnology ever since he was a kid. Bootsma fondly recalls summer vacations to Georgian Bay, Ontario, “I probably spent as much time in the water as I did out of it.” He continues,”I remember telling myself ‘I’m going to get a job where I can stay here all the time.’” While Harvey didn’t end up working on Georgian Bay, he was offered a job working on Lake Malawi. He continued working there while completing his Ph.D.

Microbes and Human Health: Aquatic Microbial Communities May Hold Clues about How Deadly Pathogens Spread

Aquatic ecosystems are incredibly complex, with many different biotic and abiotic factors constantly interacting. Microbial communities are a key part of aquatic ecosystems, involved in the constant flow of energy and recycling of organic matter, according to Science Direct .  The true scope of microbial community impacts on aquatic ecosystems is still not entirely understood. Eric Benbow, a professor of community ecology at Michigan State University, is exploring how microbial communities and pathogens may be negatively impacting human health, and how a changing climate could worsen this problem.  How Do Pathogens Arise? Benbow, along with his students and colleagues, are studying a realm of community ecology that is still relatively unknown.
