黄海暖流（YSWC）和黄海冷水团（YSCWM）是黄海最重要的水文特征，它们强烈影响着黄海区域的物质运输、沉积以及底栖和中上层环境。以往的研究主要集中在较短时间尺度（如全新世以来）的YSWC和YSCWM的形成和演化，较长时间尺度的研究相对较少。本研究对南黄海北部DLC70-3岩心（水深71.2 m）进行了高分辨率磁地层调查。结果表明，Brunhes/Matuyama极性反转边界位于59.08 m深度。在磁地层学和14c测年的双重约束下，底栖有孔虫含量揭示的3个沉积期分别对应于海洋同位素阶段（MIS） 5-MIS9、MIS11-MIS17和MIS19-MIS21的高海平面期。研究沉积物的冷水底栖有孔虫种类、总有机碳、总硫、钼元素和长链不饱和烯酮指数表明，YSCWM和YSCWM都是在中更新世以来形成的，主要是由于海平面波动和局部构造沉降的共同作用。MIS5e-MIS9、MIS19和MIS21高海平面期间，YSWC和YSCWM均有所增强。此外，YSWC和YSCWM的出现并不总是像MIS5a-5d时期那样同时发生，MIS5a-5d时期的特点是YSCWM相对较强，而YSWC的缺失。这些研究显著提高了我们对该地区YSWC和YSCWM进化机制的认识。
The Yellow Sea Warm Current (YSWC) and the Yellow Sea Cold Water Mass (YSCWM) are the most significant hydrological characteristics of the Yellow Sea as they strongly influence the matter transportation, sedimentation, and the benthic and pelagic environments of the region. Previous studies focused mostly on formation and evolution of the YSWC and the YSCWM on shorter time scales (e.g., since the Holocene) and studies on longer time scales are rather sparse. This study conducted a high-resolution magnetostratigraphic investigation on core DLC70-3 (with a water depth of 71.2 m) in the northern part of the south Yellow Sea. Results show that the Brunhes/Matuyama polarity reversal boundary is located at a depth of 59.08 m. Constrained by both magnetostratigraphy and14C dating, three sedimentation episodes revealed by the benthic foraminifera content correspond to high sea level periods of marine isotope stage (MIS) 5–MIS9, MIS11–MIS17, and MIS19–MIS21, respectively. Cold-water benthic foraminifera species, total organic carbon, total sulfur, molybdenum element, and long-chain unsaturated alkenones index of the studied sediments show that both the YSWC and the YSCWM have evolved since the middle Pleistocene mainly due to combined effects of fluctuations of sea level and local tectonic subsidence. More specifically, both the YSWC and the YSCWM were intensified during high sea level periods of MIS5e–MIS9, MIS19 and MIS21. In addition, occurrence of the YSWC and the YSCWM are not always coeval as in the MIS5a–5d period, which is characterized by relatively stronger YSCWM but absence of the YSWC. These studies significantly improve our understanding of the evolution mechanism of both the YSWC and the YSCWM in this region.
