Three-Dimensional Evolution of Intrusions

这个项目涉及普吉特海湾温盐侵入的研究。该研究旨在确定剪切产生的湍流和双重扩散过程对侵入边缘的热通量和盐通量的相对贡献。这项工作将包括两艘船对海湾内的入侵进行调查和随后的数据分析。预计这项工作将提供有关地球物理流体动力学中的一个基本问题的信息，即当剪切湍流和双重扩散这两个不同的过程同时存在时，它们是如何促成小尺度混合的。这项工作还将提供关于一种特征的结构和演变的信息，这种特征是温盐侵入，已知存在于许多海洋环境中，特别是在温盐锋附近，但尚未得到充分研究。最后，本工作将评估一种实验方法，以便将来在更海洋的环境中研究热盐侵入。

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.
