Abstract

Data of field observations carried out in the Volga Delta in the period of largest biological production from 2007 to 2010 were used to establish the existence of a distinct relationship between the concentrations of dissolved forms of mineral phosphorus and silicon. The character of this relationship varies in accordance with year-to-year variations in phytoplankton biomass, which consists of more than 90% diatoms consuming both phosphorus and silicon.
