9730433 Moum This oceanographic instrumentation development project is to build and test a low-cost and low power sensor for in situ ocean measurements of velocity on small space scales that are critical in microstructure and turbulence studies. The proposed approach is to adapt a three-component pitot tube probe, presently used for atmospheric measurements on aircraft, for use on different oceanographic instrumentation packages. The recent commercial availability of low-cost and low-power differential pressure strain gauges suggests that newly designed velocity sensors can replace certain existing oceanographic sensors that are relatively expensive and that have high power requirements. The new sensor should be capable of resolving velocities with mms-1 resolution on scales of a few centimeters. The sensors will be adapted for dropped, towed, and moored instrument packages and will be useful for planned and envisioned long-term deployments of observational platforms for physical oceanographic investigations.

9730433 Moum 该海洋学仪器开发项目旨在构建和测试低成本、低功耗传感器，用于在小空间尺度上原位海洋测量速度，这对于微观结构和湍流研究至关重要。 所提出的方法是将目前用于飞机大气测量的三部件皮托管探头改造为用于不同的海洋仪器包。最近低成本、低功耗差压应变计的商业化表明，新设计的速度传感器可以取代某些相对昂贵且具有高功率要求的现有海洋传感器。新传感器应该能够在几厘米尺度上以 mms-1 分辨率解析速度。这些传感器将适用于投放、拖曳和系泊的仪器包，并将有助于计划和设想的物理海洋调查观测平台的长期部署。
