Construction of a New Fine- and Microstructure Profiler

0118401Polzin/WHOIThe project supports the design, construction and testing of a new instrument to measure velocity on vertical scales that range from the microscale to the depth of the ocean. This instrument will have the unique capacity to obtain profiles of turbulent quantities to within a few meters of the bottom of the deep ocean and thus be able to sample both the upper part of the bottom boundary layer and the ocean interior. The design is based on an existing profiler that is nearing the end of its working life. However, design enhancements will permit closer approaches to the sea-floor, more accurate measurements and greater data storage. It is anticipated that the instrument will be used in future research into a variety of scientific questions about the ocean in which small-scale mixing and small-scale structure in the density field are important. These include questions about the maintenance and evolution of the large-scale stratification and circulation of the ocean as well as questions concerned with how tracers are mixed through the ocean.

0118401POLZIN/WHOITHE项目支持新仪器的设计，构造和测试，以测量从微观尺度到海洋深度的垂直尺度上的速度。 该仪器将具有独特的能力，可以在深海底部的几米内获得湍流数量的概况，从而能够对底部边界层的上部和海洋内部进行采样。 该设计基于现有的探索者，该档案师即将结束其工作寿命。 但是，设计增强功能将允许更紧密地进入海底，更准确的测量和更大的数据存储。 预计该仪器将在未来的研究中用于有关海洋的各种科学问题，其中小规模混合和密度领域中的小规模结构很重要。 这些问题包括有关大规模分层和海洋循环的维护和演变的问题，以及与示踪剂如何通过海洋混合的问题。
