利用南海东北部黑潮经巴士海峡进入南海的海域表层沉积物中常见的热带海洋浮游硅藻Nitzschiamarina、Racsoleniabergonii和Azpeitiaafricana/Azpeitianeocrenulata，分析了黑潮对南海的影响。在过去的115000年中，黑潮的影响似乎在主要的温暖时期相对较强，在较小的程度上，在较小的温暖时期。最强的影响发生在全新世的主要部分和海洋同位素阶段（MIS）5e的非常晚期阶段。黑潮对南海的影响有两个变化幅度：大的变化发生在冰期和间冰期之间的变化，而较小的变化似乎在冰期和间冰期以及全新世都出现过。气候/海洋变化和海平面变化可能是黑潮对南海影响的两个最重要的机制。黑潮和季风相关过程之间的相互作用也可能发挥了作用。然而，由于对现今黑潮海流的了解有限，以及由于古地理的显著变化而缺乏与古代南海的现代类似物，这种关系很难建立。版权所有© 2006约翰威利父子有限公司。
We used the tropical oceanic planktonic diatom species Nitzschia marina, Rhizosolenia bergonii and Azpeitia africana/Azpeitia neocrenulata, most commonly found in the surface sediments of the northeasternmost South China Sea (SCS) where the Kuroshio Current enters the SCS through the Bashi Strait north of Luzon, to analyse the influence of the the Kuroshio Current on the SCS. The impact of the Kuroshio Current seems to be relatively strong during major warm periods and, to a lesser degree, in minor warm periods during the last 115 000 years. The strongest influence took place during the main part of the Holocene and during the very late phase of Marine Isotope Stage (MIS) 5e. It is possible to distinguish two magnitudes of change in the impact of the Kuroshio Current on the SCS: large changes occurred at shifts between glacial and interglacial conditions, while smaller changes seem to have recurred in both glacial and interglacial episodes as well as during the Holocene. Climatic/oceanographic changes and sea‐level variations were possibly the two most important mechanisms for the varying influences of the Kuroshio Current on the SCS. The interaction between the Kuroshio Current and monsoon‐related processes may also have played a role. However, because of restricted knowledge of the present‐day Kuroshio Current and the absence of a modern analogue to the ancient SCS due to the marked changes in palaeogeography, this relationship is difficult to establish.
