Biogeochemical Processes of Phosphorus and Silicon in the Bohai Sea

Despite the role of phosphorus as one vital nutrient, the distributions and dynamics of marine phosphorus pools are less well characterized in comparison with those of the bioelements carbon and nitrogen (Suzumura and Ingall, 2004). Phosphorus is the key element for phytoplankton growth and one of the factors in coastal estuarine and seawater eutrophication. Recently, phosphorus has been observed to limit phytoplankton production in both coastal waters and the open sea.

Biogeochemical Processes of Phosphorus and Silicon of Surface Sediments in the southern Bohai Sea... 

Abstract In this chapter the biogeochemical processes in the Bohai Sea are described. The main contents deal with the distributions, transformation, and their controlling factors of carbon, nitrogen, phosphorus, silicon, and pollutants such as heavy metals and persistent organic pollutants (POPs) in the seawaters and sediments. In the Bohai Sea, human activity and riverine input are the most important controlling processes in the variation of biogenic elements and pollutants.
