Abstract

Abstract

The data of concentrations of suspended matter, temper ature and salinity in the northern East China Sea (ECS) were collected in June 1986, December 1996, February 1997 and July 1998 respectively.The distribution, its influential factors and transport of suspended matter in the northern ECS in winter and summer are studied.The results indicate that the distribution of suspended matter in the study area shows a seasonal variation, that is, the concentrations of suspended matter in this area in winter are much higher than those in summer.The influential factors for the distribution and transport of suspended matter in the study area are the ECS current circulation, storm and tidal current, and the controlling factor is the ECS current circulation.The suspended sediments from the Changjiang discharging into the sea can not almost be crossed to the east of 124°00'E both in winter and summer due to the obstr uction of Taiwan Warm Current (TWC).The diffusive area of the Huanghai Coastal Current (HCC) carrying a massive suspended matter resuspended in the old Huanghe subaqueous delta in the northern Jiangsu Province southeastwards in the winter is evidently larger than that in summer.The most shelf suspended matter in Section 32°N is limited in the west of 126°30'E due to the obstruction of the Huanghai Warm Current (HWC) both in winter and summer.The most shelf suspended matter in Section P-N also can not almost be transported to the shelf margin in winter and summer because of the obstruction of the TWC and climbing water of the Kuroshio Current.It is suggested that the possible area for the transport of suspended matter from the shelf to the Okinawa Trough in the northern ECS is in the shelf margin corresponding to the southeastern edge of the HCC with high concentration of suspended matter, and this main season is the w inter not the summer.
