Cores DOC024,retrieved from the northern Okinawa Trough in the East China Sea,are used to reconstruct the upwelling evolution over the last 7 300 years based on a multi-proxy approach including the combination of planktonic foraminifer fauna,Neogloboquadrina dutertrei δ18O,sea surface temperature(SST)and depth of thermocline.
对取自冲绳海槽北部的DOC024岩心进行了浮游有孔虫氧同位素和统计分析,依据浮游有孔虫群落组合和Neogloboquadrina dutertreiδ18O的记录以及表层海水温度、温跃层深度的变化揭示了近7300aBP以来日本九州西南海区上升流的演化过程。
Our results indicate that winter SST varied over ~5℃ in the glacial-interglacial cycles and the depth of thermocline(DOT) has shoaled gradually since 1.
6 Ma以来冰期旋回中赤道西太平洋的表层海水温度和温跃层深度的变化,为研究西太平洋暖池的变动提供了重要依据。
Glacial-interglacial fluctuations and long-term changes in carbonate dissolution and preservation, sea surface temperature (SST), depth of thermocline (DOT), paleoproductivity and predominant PF species as responding to the East Asian paleo.
11′E，水深2，772米)997个样品中浮游有孔虫群的研究，揭示了210万年来南海南部高分辨率(约2千年)的古海洋学变化历史，展示了碳酸盐溶解与保存、海水表层温度、温跃层深度、古生产力以及浮游有孔虫主要属种在冰期-间冰期和长时间尺度上的变化，以及对东亚季风和热带气候演化的响应。
The relationship between the thermocline depth of tropical ocean and the intensity of the South China Sea summer monsoon;
热带海洋温跃层深度与南海夏季风强度关系探讨
Affected by the South China Sea(SCS) monsoon and complex topography,the circulation field in the SCS has complicated spatial structure and obvious seasonal variations,and the meso-scale eddies frequently occurred in the sea area,so these features inevitably affect the horizontal distributions and seasonal variations of the thermocline depth in the SCS.
受南海季风和复杂地形的影响,南海环流场具有复杂的空间结构和明显的季节变化,同时此海域又是中尺度涡多发海域,这些特征必然对南海温跃层深度的水平分布及季节变化有显著影响。
