Smart buoy for measuring water pollutants

All over the world, lakes, rivers, and coastal waters are threatened by high nutrient inputs. Nitrate or phosphates from waste-waters or fertilizers causes eutrophication. The consequence: Algae, in particular cyanobacteria (blue-green algae), grow uncontrollably and may release toxic substances. Hence, extensive water monitoring is indispensable for drinking water supply and water protection. Researchers have now develop a smart monitoring system, combining various technologies in a depth profile-measuring multi-sensor buoy for monitoring water bodies and in particular algae growth.
