南海中部 1 993～ 1 995年连续两年的浅层和深层时间系列沉积物捕获器试验 ,揭示浮游有孔虫总通量以及Globigerinoidessacculifer,Globigerinoidesruber,Neogloboquadrinadutertrei,Globigerinitaglutinata等种的通量和相对百分数在东北季风和西南季风盛行期出现高值 ,而Globigerinabulloides,Pulleniatinaobliquiloculata和Globorotaliamenardii等种则仅在冬季东北季风盛行期出现高值 .此外 ,还发现浮游有孔虫属种的通量呈现出明显的年际变化 .研究表明这种季节和年际变化主要受与东亚季风相关的表层初级生产力和海洋水文条件变化的控制
Shallow and deep time series sediment traps experiments conducted in Central South China Sea from 1993 to 1995 for two consecutive years revealed the total flux of planktonic foraminifera and the relative percentages of Globigerinoidessacculifer, Globigerinoidesruber, Neogloboquadrinuteuterei, Globigerinitaglutinata and other species in the northeast Monsoon and southwesterly monsoon high, while Globigerinabulloides, Pulleniatinaobliquiloculata and Globorotaliamenardii only appeared high in the winter monsoon prevalence period.In addition, it was also found that the flux of planktonic foraminifera showed a significant interannual variation The study shows that this seasonal and interannual variation is mainly controlled by changes in the primary productivity of the surface and changes in ocean hydrological conditions associated with the East Asian monsoon
