| Abstract: | Light transmission data collected from June to July 1987 and from February to March 1997 by theR/V Kexue 1 in the East China Sea were used to analyze its distribution characteristics and its relation to the sediment transport
in this sea. Some results obtained were: (1) The Taiwan Warm Current flowing northwards seemed to be a barrier preventing
suspended matter discharged from the Changjiang River Estuary from continuously moving southeastward and causing the suspended
matter to flow along a path near 123°30′E in summer and 123°00′E in winter. (2) Suspended matter in the area adjacent to the
Changjiang River Estuary could not be transported southward along the coast in summer due to opposing offshore currents including
the Taiwan Warm Current flowing northward and the Changjiang Diluted Water turning northeastward. (3) The thermocline and
temperature front bar suspended matter from crossing through.
