the rapid increase of algae in an aquatic environment.

rapid growth of phytoplankton in water bodies usually in the surface layers. May be hazardous both through the production of toxins and through the blocking of insolation to lower layers.

A large, often considered excessive, growth of algae on or near the surface of water (lakes or sea), occurring naturally or as a result of an oversupply of nutrients from organic pollution. United Nat [..]

A rapid increase or accumulation in the population of algae in an aquatic system.

A reproductive explosion of algae in a lake, river or ocean.

A rapid growth of large amounts of micro- or macroalgae or cyanobacteria in water.

A sudden, rapid growth of algae in lakes and coastal oceans caused by a variety of factors including, for example, warmer surface waters or increased nutrient levels. Some algal blooms may be toxic or [..]

An algal bloom is a proliferation of either phytoplankton or seaweed and is a natural phenomenon. However, nutrient pollution has resulted in a substantial increase in algal blooms along many coastal regions over the past two decades. Phytoplankton blooms can produce toxic effects on humans and other organisms, cause physical impairment of fish and [..]

Sudden, massive growths of microscopic and macroscopic plant life, such as green or bluegreen algae, which develop in lakes and reservoirs, which can affect water quality adversely and indicate potent [..]

A condition resulting from excessive nutrient levels or other physical and chemical conditions that enable algae to reproduce rapidly.

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, [..]

An Algal Bloom where the algae produce powerful toxins that can kill fish, Birds, and Mammals, and ultimately cause illness in Humans. The harmful bloom can also cause Oxygen depletion in the Water du [..]

A excessive growth of algae, usually as a result of excess nutrients in the water. Algal blooms can be harmful, due to reduced amounts of oxygen in the water as the excessive amounts of algae die, see [..]

An extensive growth of algae in a body of water (river, lake, dam), usually as a result of high nutrient levels in the water.

Sudden, massive growths of microscopic and macroscopic plant life, such as green or blue-green algae, which can, under the proper conditions, develop in lakes, reservoirs, and ponds.

High number of algal cells in the water, leading to a green to brown color in the water. Algal blooms often lead to fish and shellfish kills due to chemical production, oxygen depletion in the water d [..]

a phenomenon whereby excessive nutrients within a river, stream or lake cause an explosion of plant life which results in the depletion of the oxygen in the water needed by fish and other aquatic life [..]

A sudden spurt of algal growth due to high concentrations of plant nutrients (eutrophication), which can affect water quality adversely. Blooms can result in oxygen depletion and biological impacts su [..]

a heavy growth of algae in and on a body of water; usually results from high nitrate and phosphate concentrations entering water bodies from farm fertilizers and detergents; phosphates also occur naturally under certain conditions.

the rapid and excessive growth of algae; generally caused by high nutrient levels combined with other favourable conditions. Blooms can deoxygenate the water leading to the loss of wildlife.

  the rapid development of algae in aquatic systems resulting from nutrient enrichment. Algal blooms can be highly detrimental to the functioning of aquatic ecosystems, fish kills being the most vi [..]

An event of high phytoplankton biomass.
