English Abstract

The SeaWiFS loaded on SEASTAR is used as remote sensing data source. With the in-situ data of suspended sediment concentration (SSC) and total particulate phosphorus (TPP), and inverse regression equation, which suggests the exponential relationship between in-situ suspended sediment concentration data and in-situ radiance data, is employed: y(subscript ssc)=0.382 6exp[4.9748(R670/R555)], r^2=0.9179. Meanwhile the concentration of particulate phosphorus can be obtained by the following algorithm: y(subscript TPP)=0.0076x(subscript ssc)+0.1599, r^2=0.720. So the distributive characteristics of suspended sediments and particulate phosphorus in the Changjiang River Estuary and nearshore were retrived through satelite data. The result suggests that (1) the retrieved concentration distribution accords with the ground trouth, and reflects the actual transport path of ocean current to some extent; (2) the concentration of TPP declines gradually from inshore to offshore; and (3) the algorithm is only applicable for Case Ⅱ water, not for Case Ⅰ water.
