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/Alford该项目涉及对普吉湾温盐侵入的研究。 这项研究旨在确定的相对贡献，在入侵的边缘，剪切产生的湍流和双重扩散过程的热量和盐通量。 这项工作将包括对海湾内的入侵进行两艘船的调查，并随后进行数据分析。 预计这项工作将提供有关地球物理流体动力学的一个基本问题的信息，这两个不同的过程，剪切湍流和双扩散，有助于小尺度混合时，都存在的方式。 这项工作还将提供关于一类特征的结构和演变的资料，即已知存在于许多海洋情况中，特别是在温盐锋附近，但尚未得到充分研究的温盐侵入。 最后，这项工作将评估一种实验方法，以便将来可能用于研究海洋环境中的温盐入侵。
