摘要 黑潮延伸系统研究（KESS）旨在量化控制黑潮延伸和再循环环流的变化及其相互作用的过程。为了实现这一目标，部署了一套仪器，包括 43 个配备底部压力计和电流计的倒置回声测深仪 [电流和压力记录倒置回声测深仪 (CPIES)]。该阵列以日本东部第一个准静止曲流波峰和波谷为中心，这也是涡流动能最高的区域。 KESS 是第一个部署大量此类新型 CPIES 仪器的实验，其独特之处在于这些仪器部署在接近其操作极限的水深（5300-6400 m）中。提供了从 KESS CPIES 阵列产生温度、比容异常和速度的介尺度分辨四维环流场的方法的全面叙述。此外，一种改进的去除 p 的技术...
Abstract The Kuroshio Extension System Study (KESS) aimed to quantify processes governing the variability of and the interaction between the Kuroshio Extension and the recirculation gyre. To meet this goal, a suite of instrumentation, including 43 inverted echo sounders equipped with bottom pressure gauges and current meters [current and pressure recording inverted echo sounders (CPIES)], was deployed. The array was centered on the first quasi-stationary meander crest and trough east of Japan, which is also the region of highest eddy kinetic energy. KESS was the first experiment to deploy a large quantity of these new CPIES instruments, and it was unique in that the instruments were deployed in water depths (5300–6400 m) close to their limit of operation. A comprehensive narrative of the methodology to produce mesoscale-resolving four-dimensional circulation fields of temperature, specific volume anomaly, and velocity from the KESS CPIES array is provided. In addition, an improved technique for removing p...
