Shear Profiling and Analysis in Conjunction with Direct Measurements of Dissipation and Diffusion

将在1992年秋和1993年春进行详细的垂直速度剪切测量，以支持北大西洋示踪剂释放实验，使用称为笛卡索潜水器的自动剖面仪。观察将在四个不同的地点进行，并与微观结构剖面相一致。本研究的科学目标是将温跃层中的湍流混合过程与背景内波场联系起来，并将由示踪剂扩散获得的直接扩散率测量与基于湍流耗散率的涡动扩散率模型联系起来。

Detailed vertical velocity shear measurements will be conducted in the fall of 1992 and spring of 1993 in support of the North Atlantic Tracer Release Experiment (NATRE) using an autonomous profiler called Cartesian Diver. The observations are to be conducted at four different locations in concert with microstructure profiling. The scientific objectives of this study are to relate turbulent mixing processes in the thermocline to the background internal wave field and to relate direct diffusivity measurements obtained from tracer diffusion to eddy diffusivity models based on turbulent dissipation rates.
