| 印尼贯穿流源区指的是苏拉威西海东部、马鲁古海北部以及棉兰老岛以东和巴布亚新几内亚岛以北的海域，其海洋环流的结构和变异对全球大洋环流的物质和能量平衡以及气候变化有重要影响，但是却缺乏大规模的现代海洋观测。本文总结近几年来基金委西太平洋开放共享航次、全球变化研究国家重大科学研究计划项目以及中科院海洋先导专项项目——“主流系与西太平洋暖池变异机制及其气候效应”等项目在低纬度西太平洋和印尼贯穿流源区的观测成果，初步刻画了印尼贯穿流源区海洋环流的多尺度结构特性，阐明这一海区环流对厄尔尼诺与南方涛动（ENSO）动力学、季节内振荡研究以及全球变暖减缓和加速的重要性。介绍了项目团队在过去几年里，通过国际合作，促成中国科学院海洋研究所与印尼科学院海洋研究中心达成战略合作伙伴关系。目前，双方已经在印尼海和印尼贯穿流关键海峡进行了卓有成效的合作观测，建成了有史以来最大规模的印尼海同步潜标观测网，为探讨印尼贯穿流变异及其在全球气候变化的作用问题和服务国家“一带一路”倡议提供了坚实的数据基础。 |

| Abstract: |
| The Pacific entrance of the Indonesian Throughflow refers to the area composed of the eastern Sulawesi Sea, northern Maluku Sea, and the western Pacific Ocean southeast of Luzon and north of Papua New Guinea. The ocean circulation in this area is very important to global ocean mass and heat balances and to climate changes, but is least observed historically. Based on a review of historical studies in the area and the latest observations during the multiple cruises in the western Pacific Ocean conducted by the Institute of Oceanology of the Chinese Academy of Sciences (IOCAS) since 2010, we give a preliminary description of the multiple-scale characters of the regional ocean circulation, the importance of which on the dynamics study of El Niño and the Southern Oscillation, on the intraseasonal variability, and on the hiatus and expedition study of the global warming are discussed. These western Pacific cruises are supported by the National Science Foundation of China Share Cruise Project, the National Basic Research Program of Global Change Project, and the Strategic Priority Project of the Chinese Academy of Sciences under its first theme “Dynamics and climatic effects of the western Pacific main ocean currents and warm pool variability”. In the past few years, we have worked with the Research Center for Oceanography of the Indonesian Institute of Sciences (RCO/LIPI) to launch multiple oceanographic surveys in the Indonesian seas and conduct time series measurements in key channels of the Indonesian Throughflow. A mooring array of the largest scale in history has been constructed in the Indonesian seas. Based on the international cooperation, strategic partnership between IOCAS and the RCO/LIPI has been established. The oceanographic data obtained through the international cooperation will provide valuable information to support the study of the variability of the Indonesian Throughflow and its role in climate changes, and to serve the “One Belt and One Road” national policy. |
