Definition noun Photosynthetic (plant-like) constituent of plankton, mainly comprised of unicellular algae Supplement Plankton pertain to the small organisms that drift, float, or weakly swimming in aquatic habitats. This is called a phytoplankton "bloom" and in the blooming, these little guys take up tons of CO2 out of the water, which in turn pulls CO2 out of the air (ie, atmosphere), and - presto! a definition would not lend to many bloom observations in mesotrophic or oligotrophic waters, and it clearly contra-dicts the conclusion from the 1984 ICES Exceptional Plankton Bloom Meeting stating that a bloom is a deviation from the ‘‘normal cycle of phytoplankton biomass’’ (Parker 1987).
