NATURAL PHENOMEN … RED TIDES

RED TIDES

Also known as the algal bloom, the Red Tide is the rapid accumulation of estuarine, marine, or fresh water algae in a water column, which tints the water red.

When the algae, or phytoplankton, accumulate in such a manner, they form dense clouds near the water’s surface. Since the phytoplankton is usually brown, red and green, the water, naturally, reflects this colour on the surface.
