Preferred term

red tide  

Definition

  • RED TIDE IS the common term used to refer to the dramatically increased concentration of microscopic phytoplankton or algae which tend to accumulate near marine or fresh water surfaces. Currents play an important role in providing nutrients and transporting the algae, while the red in their name comes from the algae's reddish pigment, which gives the appearance of a red color to surface waters.
