Phosphorus biogenic silicon

The time-sequence pattern of P deposition to the sediment surface differed markedly from that observed with silicon (25). Biogenic silicon underwent relatively little dissolution in the water column as compared with phosphorus, which resulted in a bell-shaped deposition pattern (Figure 11). Rapid regeneration of P during sedimentation resulted in a slower net settling rate for P than for biogenic silicon. 

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.
