dinoflagellate bloom

Definition

Rapid and localized increase of planktonic species, often in spring or autumn, can cause large temporary concentrations of these organisms to dominate the community and result in discoloured waters (red tides). Phytoplankton (algal) blooms may be associated with the release of toxins (e.g. blooms of the dinoflagellate Gymnodinium).
