| 摘 要： | 对南海北部N-31柱状样沉积物进行了浮游有孔虫定量分析鉴定、氧碳同位素、碳酸盐含量和粒度测试以及AMS14C测年,并采用古生态转换函数计算了表层海水古温度和温跃层深度,揭示了该海区约55 ka以来的古海洋环境特征.转换函数计算的表层海水古温度结果表明,夏季温度的变化范围为27.0～29.6℃,变化幅度为2.6℃,冬季温...

| Abstract: | The South China Sea is the largest marginal sea in the western Pacific Ocean and its' north and south are wide continental shelf.There are many rivers flow into the South China Sea.The high-resolution sediment records abundant environmental information of land and sea.This area has become one of hotspots on paleoceanography research and made a lot of research results.Planktonic foraminifera are very sensitive to changes of marine environment.Sea water temperature changes can directly affect the migration an... |
