The continual bottom flow provides an effective ventilation system, drawing in new oceanic water and expelling brackish water. Although the surface appears calm, the underwater intersection of fresh and salt water roils with turbulent eddies as strong as any in the ocean. A pH of less than 7 indicates acidity, whereas a pH of greater than 7 indicates a basic or alkaline condition. These "blue-green" algae blooms, are a form of bacterial known as Cyanobacteria, whose cells may release a toxin when they die. Phycocyanin is measured using a fluorescence sensor.
