The Skidaway Institute of Oceanographic will acquire a two- axis, fiber-optic laser doppler velocimeter (LDV) for the study of benthic boundary layers. Studying the small-scale dynamics between seafloor sediments and the water just above requires a multi-dimensional approach. Such studies involve laboratory and field measurement programs, and numerical modelling. Recently developed LDVs offer a modern way to non-invasively measure mean velocities, turbulence intensity in both along-stream and vertical directions, and turbulent shear stress. The LDV flow measurement system will be integrated into a large flume research facility being constructed with institutional funds. It will serve a number of investigators in the Southeastern U.S. working on multidisciplinary problems relating to sediment geochemistry, sediment transport, and benthic ecology.

斯基德韦海洋研究所将获得一台两轴光纤激光多普勒测速仪(LDV)，用于研究海底边界层。研究海底沉积物和上面的水之间的小尺度动力学需要多维的方法。这类研究涉及实验室和现场测量方案，以及数值模拟。最近发展起来的LDV提供了一种非侵入性测量平均速度、沿流和垂直方向的湍流强度以及湍流剪应力的现代方法。LDV流量测量系统将被整合到一个大型水槽研究设施中，该设施正在用机构资金建造。它将为美国东南部的一些研究人员提供服务，他们致力于研究与沉积物地球化学、沉积物运输和底栖生物生态学有关的多学科问题。
