	Redtides
		Outbreaks of red tide along the South African coast are reported periodically in the media, with warnings to the public about the dangers of collecting and consuming shellfish in the affected areas.
		Red tides are therefore not a result of sudden population explosions of phytoplankton attributable to increased division and growth rates, but result from confinement or concentration of phytoplankton following normal population increases to such an extent that they discolour the water.
		The mass mortality of the red tide organisms once the nutrients have been depleted results in an increase in the number of bacteria which are responsible for decomposition in the sea.

	ABOUT RED TIDE ...
		Red tide cells occur naturally through out the Gulf and develop into highly concentrated “bloom” conditions as a result of physical, chemical and biological factors that are conducive to bloom formation most frequently along the unique, shallow environment of the west
		Scientists are working very hard to understand the complex combination of these factors that result in a red tide bloom, so that we might predict bloom formation and investigate possible ways to eliminate or reduce their adverse impacts on marine life and public health.
		Red tide is the result of a massive multiplication (or "bloom") of tiny, single celled algae called Karenia brevis, usually found in warm saltwater, but which can exist a lower temperatures.

	Red tide - Wikipedia, the free encyclopedia
		Red tide is an estuarine or marine algal bloom and is caused by a species of dinoflagellates, often present in sufficient numbers (thousands or millions of cells per milliliter) to turn the water red or brown.
		As another example, non- red tide algal blooms in lakes and rivers may be caused by greatly increased amounts of phosphorus or nitrogen entering an aquatic ecosystem from either sewage systems or surface runoff of agricultural fertilizers.
		Red tide can also increase fish mortality; they are also accumulated in the digestive tracts of filter feeders.

	Red Tide FAQ
		Red tide is a naturally-occurring, higher-than-normal concentration of the microscopic algae Karenia brevis (formerly Gymnodinium breve).
		When red tide algae reproduce in dense concentrations or "blooms," they are visible as discolored patches of ocean water, often reddish in color.
		Red tide is a natural phenomenon not caused by human beings.

	Offshore / Inshore Fisheries Development & Technologies: Red Tides
		However, many of the discolourations due to algae in marine waters are red, hence the origin of the terms "red tide" or "red water." The terms are now associated with the phenomenon itself, so the colour of a "red tide" is not necessarily red, but may be any other colour.
		It has been suggested that a red tide was responsible when mussels, scallops and oysters developed a bitter taste so unpleasant and persistent that they were unable to market the shellfish for 7 months (long after the disappearance of the red tide).
		Red tides - harmful and non-harmful - have a long history and are a "fact of life" or a part of nature.

	NASA - An Active Florida Hurricane Season Adds to Red Tide
		Red tides, which may or may not be harmful, are primarily caused by the toxic phytoplankton, Karenia brevis on the west Florida Shelf.
		Red tides occur in the same area off west-central Florida almost every year, mostly between August and March, from north of Tampa to south of Naples, Fla. The 2005 red tide poisoned the ocean waters and killed fish, turtles, birds, and marine mammals.
		We believe that submarine groundwater discharge provides the missing nutrients, and may trigger and maintain red tides off west-central Florida." Hu and his colleagues proposed that the unusual number of hurricanes in 2004 resulted in high runoff, and in higher than normal discharge of groundwater that was deposited along the west Florida coast throughout 2005.

	START: Solutions To Avoid Red Tide on Florida's Gulf Coast
		Red tides are caused by the explosive growth and accumulation of certain microscopic algae, predominantly dinoflagellates, in coastal waters.
		The dinoflagellate Karenia brevis, or K.brevis, which is the predominant red tide organism in the Gulf of Mexico (and can also occur on the Atlantic side of the Florida coast) can kill fish in vast numbers, make shellfish poisonous to humans, and release toxic airborne irritants that drive coastal residents and tourists from beaches.
		The red tide is then transported into the nutrient-rich, shallow waters by winds and/or currents, where it continues to multiply to harmful levels.

	ABOUT RED TIDE ...
		The Florida red tide is caused by blooms of a dinoflagellate that produce potent neurotoxins.

	Surfrider Foundation A-Z: Red Tide and Harmful Algal Blooms
		The term "red tide" is thus a misnomer because they are not associated with tides; they are usually not harmful; and those species that are harmful may never reach the densities required to discolor the water.
		Red tides are natural occurrences; the plankton community becomes dominated by one or a few species at extraordinarily high concentrations.
		To really know why red tides appear and to be able to predict their appearance, dense and continuous sampling all up and down the Southern California Bight for several months prior to a bloom would have to be done.
