A study on suspended matters in the South Huanghai Sea in summer time

A joint investigation of marine geoloy in the South Huanshai Sea was carried out by the Institute of Oceanology,Academia Sinica,and the Woods Hole Oceanographic Institution,USA during 1983~1984.This paper reports the investigation results of the suspended matters in the water column at 55 stations in July,1984 (summer time).
The highest concentration region where the value is less than 0.5 mg/L,is found in the central part of the study area and the southern part of Shandong Peninsula.The Taiwan Warm Current which might obstruct the discharge of the Changjiang River to the east of the sea,appears in the distribution of the suspended matters outside the Changjiang River Estuary.
Although lots of materials are brought into the sea during the high flow period of the Huanghe and the Chansjiang Rivers in July,this does not form the main scarce of the suspended matters.The main source is the resuspension of depesits.The materials brought by rivers come the second,and biogeneons components in the sea come the third.
The substances discharged from present rivers nave an effect on the suspended matters near the north and south boundary lines of the study area.
There are therawcline,halacline and pycnacline in the offshore water column.Their existence restricts the bottom materlals from being tra}ported upward.The motion and movement of the materials in water column go on mainly in bottom layer.The way of its process may be in the farm of suspending-depositing-resuspending-redepasiting.
There exists intensely an organic influence in the bottom water of the Huanghai Sea,as it is shallow water area.
