从太阳号(SONNE95)1994航次的南海表层沉积物中分离出了有孔虫,并分析了它们的氧碳同位素组成.浮游有孔虫氧同位素组成的空间变化,主要和海洋物理因素有关.在蒸发作用较强的东沙、中沙和南沙海域,表层种G. ruber氧同位素偏重,而在淡水来水方向,即南海北部、西部和西南部,其氧同位素偏轻;次表层种P. obliquiloculata的氧同位素等值线图,指示氧同位素较重的黑潮水经由巴士-巴林塘海峡进入南海,并与氧同位素偏轻的南海冲淡水混合.浮游有孔虫的碳同位素空间变化趋势主要受海洋生物因素影响.在饵料来源丰富的珠江口外水域,以及光照充沛的南沙海域,G. ruber的碳同位素偏轻.在黑潮水所经之处,P. obliquiloculata的碳同位素偏重.浮游有孔虫氧碳同位素等值线在东沙和中沙海域变化梯度较大,与黑潮入侵引起的海水环流有关.
