Abnormal outbreaks of aquatic cyanobacteria have severely impacted water quality in many coastal areas and lakes worldwide. Cyanobacteria can increase significantly when nutritional, temperature, climatic, and light conditions are favorable and appear in a high-density accumulation state at the water's surface. Such a state is comparable to a limitation of the natural vertical migration function of cyanobacteria. It is thought to cause physical effects not seen in everyday physiological phenomena of aquatic cyanobacteria. In this study, we investigate the forces that act on cyanobacteria to maintain high-density accumulation at the water surface by conducting tank experiments.
