Collaborative Research: Kuroshio Extension System Study

0221008瓦特黑潮延伸系统研究的总体目标是确定和量化控制黑潮延伸和再环流的可变性和相互作用的动力和热力学过程。来自美国三家机构的调查人员将部署一个最先进的阵列，包括系泊剖面仪和海流计系泊设备，以及配备近底部压力和电流传感器的倒置回声探测仪。剖面浮标将监测黑潮延伸部以南的再循环环流中的温度和盐度结构。KESS阵列的设计是为了协同使用这些工具，以比它们中的任何一个单独完成的更完整的方式来观察黑潮延伸。特别是，倒置回声探测仪将绘制出急流演变过程中的特征图，并与系泊剖面仪相结合，将量化跨锋面通量，而剖面浮标将监测黑潮延伸部分及其再循环环流周围的上层海洋结构。KESS将利用这些综合观测来确定和量化控制黑潮延伸区和环流的可变性及其相互作用的动力和热力学过程。该方法广泛使用了卫星数据(地表温度和海面高度)。调查人员还将与研究整个黑潮系统的日本科学家密切合作。来自KESS阵列的测量将指导作为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.
