摘要本文介绍了一种用于上层海洋水平变化采样的二维系泊基阵的设计和性能。在马萨诸塞州湾水深84 m处部署了系泊装置，用于测量内波的水平结构。系泊设备上装有三个声学海流计（ACM），它们沿一条170米的水平电缆间隔沿着，该电缆在海面以下20米的两个水下浮标之间伸展。五根25米长的垂直乐器弦悬挂在水平缆绳上。一个安装在底部的声学多普勒流速剖面仪（ADCP）被部署在附近，以测量整个水柱的流速。安装在水下浮标和垂直仪器串上的压力传感器用于测量阵列响应于海流的垂直位移。从ACM和ADCP的测量被用来构建随时间变化的，二维电流场。当前字段用于...
Abstract This paper describes the design and performance of a two-dimensional moored array for sampling horizontal variability in the upper ocean. The mooring was deployed in Massachusetts Bay in a water depth of 84 m for the purpose of measuring the horizontal structure of internal waves. The mooring was instrumented with three acoustic current meters (ACMs) spaced along a 170-m horizontal cable that was stretched between two subsurface buoys 20 m below the sea surface. Five 25-m-long vertical instrument strings were suspended from the horizontal cable. A bottom-mounted acoustic Doppler current profiler (ADCP) was deployed nearby to measure the current velocity throughout the water column. Pressure sensors mounted on the subsurface buoys and the vertical instrument strings were used to measure the vertical displacements of the array in response to the currents. Measurements from the ACMs and the ADCP were used to construct time-dependent, two-dimensional current fields. The current fields were used as in...
