Abstract

Abstract

Biogeochemical process of major elements has been systematically studied in sinking particulate of Nansha coral reef lagoons,the South China Sea.The main results are as follows:The contents and vertical fluxes of major elements in Nansha coral reef lagoons were different.Vertical fluxes of most major elements in Yongshu Reef lagoon were higher than those in Zhubi Reef lagoon.Ca has the highest flux,about 1.4 g/cm²·d).Na,K,Ca,Mg and Sr were transferred onto sea floor mainly in carbonate in Yongshu Reef lagoon,Fe,I and Ba in iron-manganese oxides and Al,Br in silicate,Cl transformation tended to be in the forms of carbonate and silicate.Pdost of Br,K,A1,I in sinking particulate can recycle into seawater,half of total Mg,Na and Cl can be released into seawater.Most of Ca,Sr,Ba and Fe can be really precipitated into sediment.The order of precipitation ratio was Ca >Mg >I >Al >Br >K.Vertical fluxes of major elemenu have close relationship with SST.Na and other 8 elements decreased exponentially with SST,but K and Ba had not the relationship.The order of sensitivities to SST was Fe >Br >Sr >Ca >Na >Cl >Mg >I >Al.The vertical flux changes of Fe and Br can react SST variation.
