| 摘 要： | 西北太平洋黑潮延伸体是全球海洋动力过程最复杂、对全球气候变化最敏感和全球海洋渔业产量最大的区域之一,然而,目前对该海区物理、生态及生地化循环等过程的认识仍受限于长期连续海洋观测资料的缺乏。本文回顾了国际上针对黑潮延伸体海区的相关观测情况和取得的主要进展,介绍了近年来我国在该区域观测系统的构建工作及取得的初步成果,包括构建了全球首个西北太平洋黑潮延伸体定点观测系统;发现黑潮延伸体海区海洋涡旋的平流效应对该海区模态水的总潜沉率贡献超过一半,所携带当地的模态水只需要一年半的时间就可到达海盆的西边界;基于潜标首次展示了黑潮延伸体区域3种不同类型次温跃层涡旋流速的直接观测结果,为开展其生成消亡机制及其全球次表层物质能量输运提供了重要的现场观测基础。最后,本文展望了今后观测系统的发展方向,即在跨圈层和多学科交叉方面发展成为我国在西北太平洋重要的深远海综合观测网络。这将为揭示多尺度物理-生物过程耦合、深海能量串级及其气候效应与深海碳循环等领域实现突破提供重要的观测支撑。

| Abstract: | The Kuroshio Extension (KE) in the Northwest Pacific is one of the regions that are dynamically most complex, most sensitive to climate change and have the most productive fishing ground in the global ocean. However, it is also a region with the least long-term continuous observation, which can hinder our understanding of the physical, ecological and biogeochemical processes in the region. This paper reviews the recent progress and accomplishments in the international KE observations as well as the ongoing efforts by Chinese scientists-including in 2020 the successful construction of the Kuroshio Extension Mooring System (KEMS), the first real-time data-transmission mooring array in the Northwest Pacific. During the construction of the KEMS, it was found that subduction by eddy lateral advection accounted for more than 50% of the total subduction rate for mode waters. The mesoscale eddies could trap and transport such mode waters southwestward to the western boundary of the subtropical gyre within one and a half year. By simultaneous temperature/salinity measurements and velocity measurement from the mooring arrays, the dynamic features of subthermocline eddies (STEs) in the KE region were examined in detail. For the first time in situ evidence of three types of STEs were obtained in this region, which provided a solid observational basis for further investigation of the detailed generation and erosion mechanisms of the KTEs as well as the global subsurface mass/heat transport processes. The paper proposes that future observational systems should include integrated open-ocean observational platforms for multisphere, multidisciplinary studies, which can provide important observational support for the understanding of multiscale physical biological coupling, deep-ocean energy cascade and its climate effects, and deep-ocean carbon cycle. |
