Analytical studies will be made of the relationship between finestructure and microstructure, using data obtained from the Caribbean Sheets and Layers Transects Experiment (C- Salt) and from the Patch Experiment (PATCHEX). Optical observations in C-SALT revealed horizontal, rather than the expected vertical bands in regions favorable to salt fingers. Two analytical approaches will be used to investogate this phenomenon: fingers stretched and tilted by shear, and secondary instabilities due to horizontal intrusions. The larger scale CTD data set will be used to investigate the relationship between layer thickness and other staircase properties with the objective of better quantifying the vertical salt flux and larger scale properties. PATCHEX data will be used to investigate various aspects of shear instability and mixing, specifically the relationship between internal waves and the shear and strain fields.

将对这种关系进行分析研究 精细结构和微观结构之间的关系， 从加勒比片和层样带实验（C- 盐）和来自贴片实验（PATCHEX）。 光学 C-SALT的观察显示水平，而不是 在有利于盐指发育的区域出现了预期的垂直条带。 两种分析方法将被用来调查这一点 现象：手指因剪切而伸展和倾斜，以及 水平侵入造成的次生不稳定性。 的 更大规模的CTD数据集将用于调查 层厚与其它阶梯的关系 目的是更好地量化 垂直盐通量和更大尺度的性质。 PATCHEX数据 将用于研究剪切的各个方面 不稳定性和混合，特别是 内波以及剪切和应变场。
