Blue Tide. Seasonal winds can cause the upwelling of nutrients which in turn can cause plankton populations to bloom as "red tides." Here, a dinoflagellate population (Noctiluca sp.) turns the ocean a luminous blue colour as the disturbance by the wind triggers a light-generating chemical reaction. The production of light is thought to attract fish predators that prey on potential predators of the dinoflagellates.” Attribution: Bruce Anderson (University of Stellenbosch).
