- Abstract
Sea-viewing Wide Field-of-view Sensor (SeaWiFS) chlorophyll- a distribution in summer in the East China Sea during 1998–2007 was analyzed. Statistical analysis with K-means clustering technique allowed us to define the proper satellite chlorophyll- a concentration indicating the Changjiang Diluted Water (CDW). The spatial distributions of the higher satellite chlorophyll- a concentrations (>0.48 mg m−3) corresponded well with the distributions of lower salinity CDW (<30–32) every year. Interannual variation of the CDW area, indicated by the high satellite chlorophyll- a, correlated with the interannual variation of the Changjiang summer freshwater discharge. The correlation analysis indicated that the CDW spread eastward in the East China Sea with a time lag of 1 to 2 months after the discharge.
