0095382/AlfordThis project involves the study of thermohaline intrusions in Puget Sound. The study seeks to determine the relative contribution, to heat and salt fluxes at the edges of the intrusion, of shear-generated turbulence and doubly diffusive processes. The work will involve a two-ship survey of an intrusion within the Sound and subsequent data analysis. It is anticipated that the work will provide information about a basic question in geophysical fluid dynamics, the way in which two distinct processes, shear turbulence and double diffusion, contribute to small scale mixing when both are present. The work will also provide information on the structure and evolution of a type of feature, a thermohaline intrusion, known to be present in many oceanic situations, particularly near thermohaline fronts, but not yet well studied. Last, the work will evaluate an experimental approach for possible future use in the study of thermohaline intrusions in a more oceanic setting.

0095382/Alfordthis项目涉及Puget Sound中热盐侵入的研究。 该研究旨在确定剪切产生的湍流和双重扩散过程的相对贡献，对热量和盐通量的相对贡献。 这项工作将涉及对声音中的入侵和随后的数据分析的两件调查。 可以预料，这项工作将提供有关地球物理流体动力学中一个基本问题的信息，这是两个不同的过程，即剪切湍流和双重扩散的方式，在两者都存在时会导致小规模混合。 这项工作还将提供有关一种特征的结构和演变的信息，一种热盐侵入，已知存在于许多海洋情况下，尤其是在热盐局部附近，但研究尚未得到很好的研究。 最后，这项工作将评估一种实验方法，以在更海洋环境中研究热盐侵入的研究中可能使用。
