南海北部１９８７年９月～１９８８年１０月沉积物捕获器中颗粒物质和硅藻通量的季节性 变化受到季风气候的控制。颗粒物质与硅藻在东北和西南季风盛行期增加，在季风转变期减 少。浅层和深层的颗粒总通量、蛋白石通量、碳酸钙通量、蛋白石／颗粒总通量比值、碳酸钙／颗 粒总通量比值、有机碳／磷的比值以及浅层硅藻Ｔｈａｌａｓｓｉｏｎｅｍａ ｎｉｔｚｓｃｈｉｏｉｄｅｓ、Ｃｏｓｃｉｎｏｄｉｓｃｕｓ ｅｘｃｅｎｔｒｉｃｕｓ、Ｃｏｓｃｉｎｏｄｉｓｃｕｓ ｎｏｄｕｌｉｆｅｒ、Ｎｉｔｚｓｃｈｉａ ｍａｒｉｎａ和Ｒｈｉｚｏｓｏｌｅｎｉａ ｂｅｒｇｏｎｉｉ的通量在东北 季风期间明显地增加了，这些变化可能与１９８７年～１９８８年发生的ＥＩ Ｍｉ ｏ事件相关。
Seasonal changes in the flux of particulate matter and diatoms in the sediment trap from September 1987 to October 1988 in the northern South China Sea are controlled by the monsoon climate. Particulate matter and diatoms increased in the northeast and southwest monsoon periods and decreased during the monsoon period. Shallow and deep total flux, opal flux, calcium carbonate flux, opal / pellet flux ratio, calcium carbonate / pellet flux ratio, organic carbon / phosphorus ratio and shallow diatoms Thalassionema nitzschioides, The fluxes of Coscinodiscus excentricus, Coscinodiscus nodulifer, Nitzschia marina and Rhizosolenia bergonii increased significantly during the northeast monsoon period, and these changes may be related to the EI Mi o events that occurred between 1987 and 1988.
