Phytoplankton biomass and photosynthesis in relation to the environmental conditions in Tokyo Bay.

The article refers to phytoplankton biomass. Phytoplankton biomass and photosynthesis were investigated in relation to physicochemical environmental conditions in Tokyo Bay from May 1979 through March 1981. Vertical and seasonal variations of "chlorophyll a," photosynthetic and respiratory activity, and environmental conditions were investigated in the inner part of the bay. It is found that "Chlorophyll a" concentrations were generally high when salinity was low, but no definite relationship was observed between photosynthesis and salinity. No clear relationship was observed between chlorophyll a and nutrient concentrations.
