EM-POGO: Development of a Fast Free Falling Velocity Profiler

9617869罗斯比这个项目是为了开发一种剖面海流计，它可以从表面到深处工作，最大可达5,000米。它被称为EM-POGO，是两项成熟技术的结合，即消耗性电流剖面仪(XCP)和滴加探空仪(也称为POGO)。XCP技术得到的洋流垂直结构的相对精度为1-2厘米/S，而滴管位移测量的垂直平均速度也达到了约1-2厘米/S。整套仪器将重约15公斤，因此可以手动展开，因此可以在任何大小的船只上使用。该仪器的吸引力在于精度高、使用方便、速度快、成本低。这些属性应该会引起人们对它在许多研究应用中的相当大的兴趣。必要的技术是众所周知的；拟议的工作包括将这两种技术适应到一个操作系统中。由此产生的技术将可用于商业制造。

9617869 Rossby This project is to develop a profiling current meter that can operate from the surface to depths as great as 5000 meters. Called the EM-POGO, it is a merger of two well- established techniques, the expendable current profiler (XCP) and the dropsonde, also known as the POGO. The XCP technique yields the vertical structure of ocean currents to a relative accuracy of 1-2 cm/s, and the dropsonde displacement measures the vertically averaged velocity also to about 1-2 cm/s. The complete instrument will weigh about 15 kg enabling it to be deployed by hand and hence used from boats of any size. The appeal of the instrument lies in its high accuracy, ease and speed of use, and low cost. These attributes should lead to considerable interest in it for a number of research applications. The necessary technology is well-known; the proposed work consists of adapting these two techniques into one operating system. The resulting technology will be made available for commercial fabrication.
