Collaborative Research: Kuroshio Extension System Study

0221008 瓦特 黑潮延伸系统研究 (KESS) 的总体目标是识别和量化控制黑潮延伸和再循环环流的变化和相互作用的动态和热力学过程。来自三个美国机构的研究人员将部署最先进的阵列，其中包括系泊剖面仪和海流计系泊装置以及配备近海底压力和电流传感器的倒置回声测深仪。剖面浮标将监测黑潮延伸段以南再循环环流的温度和盐度结构。 KESS 阵列旨在协同使用这些工具，以比其中任何一个工具单独观察更完整的方式观测黑潮延伸区。特别是，倒置回声测深仪将绘制喷流演化过程中的特征图，并与系泊剖面仪相结合，量化正面通量，而剖面浮标将监测黑潮延伸区周围的上层海洋结构及其再循环环流。 KESS 将利用这些综合观测来识别和量化控制黑潮延伸区和再循环环流的变化及其之间相互作用的动态和热力学过程。所提出的方法广泛使用卫星数据（表面温度和海面高度）。研究人员还将与研究整个黑潮系统的日本科学家密切合作。 KESS 阵列的测量结果将指导作为 CLIVAR 一部分的长期观测计划的未来规划。

0221008 WattsThe overall goal of the Kuroshio Extension System Study (KESS) is to identify and quantify the dynamic and thermodynamic processes governing the variability of and the interaction between the Kuroshio Extension and the recirculation gyre. Investigators from three US institutions will deploy a state-of-the-art array consisting of moored-profiler and current-meter moorings and inverted echo sounders equipped with near-bottom pressure and current sensors. Profiling floats will monitor the temperature and salinity structure in the recirculation gyre south of the Kuroshio Extension. The KESS array is designed to use these tools synergistically to observe the Kuroshio Extension in a more complete way than any one of them could do alone. In particular, the Inverted Echo Sounders will map features of the jet as they evolve and, in combination with the Moored Profilers, will quantify the cross-frontal fluxes, while the profiling floats will monitor the upper ocean structure around the Kuroshio Extension and its recirculation gyres. KESS will use these combined observations to identify and quantify the dynamic and thermodynamic processes governing the variability of, and the interaction between, the Kuroshio Extension and the recirculation gyre. The proposed approach makes extensive use of satellite data (surface temperature and sea-surface height). The investigators will also collaborate closely with Japanese scientists studying the overall Kuroshio system. The measurements from the KESS array will guide future planning for a long term observational program as part of CLIVAR.
