Algal Bloom

The Growth of a superabundance of algae usually from an enrichment of a natural body of Water by the addition of dissolved nutrients, especially Nitrogen and Phosphorus. The enrichment may be natural, or unnatural, for example, from Water Pollution, or controlled such as is done for the Aquaculture of Phytoplankton. If the bloom becomes detrimental to Animals, it is called a Harmful Algal Bloom.
