Vector Measuring Current Meter (VMCM) Upgrade/Replacement

小行星9601625 矢量测量电流计（VMCM）由Robert Weller和Russ Davis博士开发，并由EG G Sealink System进行商业生产。 根据PI，在浮标附近的近表面区域进行高质量矢量测量的科学要求继续增加，VMCM螺旋桨流速计被认为是当前的标准。 问题是，VMCM不再是商业上可用的，最初由Sea Data Corp制造的数据记录器和读取器也不再可用或维修。该提案寻求资金，以重新设计矢量测量电路、数据采集和存储组件，从而提供一种新的、更轻、灵活、廉价和低功耗的仪器。 更换老化的磁带录音机将增加数据返回。 尺寸和重量的减小将允许在新的系泊设计中使用VMCM，例如水平阵列。 该项目将允许超过40个EG G Sea Link，Inc。 上层海洋过程小组使用的VMCM，以及在海洋学界的其余部分将可靠地使用到下一个十年。 WHOI的费用份额为159 000美元，占该项目总费用的51%。 ***

9601625 Weller The Vector Measuring Current Meter (VMCM) was developed by Drs. Robert Weller and Russ Davis and commercially produced by EG&G Sealink System. According to the PIs, the science requirements for high quality vector measurements in the near surface region near buoys continue to increase and the VMCM propeller current meter is recognized as the current standard. The problem is that the VMCM is no longer commercially available and the data recorder and reader, originally manufactured by Sea Data Corp, are also no longer available or repairable. This proposal seeks funding to redesign the vector measuring circuitry, data acquisition and storage components so as to provide a new, lighter, flexible, inexpensive and low power instrument. Replacement of aging tape recorders will increase data return. Reduction of size and weight will permit the use of the VMCM on new mooring designs, such as horizontal arrays. The project will permit the over 40 EG&G Sea Link, Inc. VMCMs that the Upper Ocean Processes group uses, as well as those within the rest of the oceanographic community to be used reliably into the next decade. WHOI's cost share of $159,000 represents 51% of the total cost for this project. ***
