OCE 96-33794 Melville The project will investigate the initial development of coherent structures in the surface boundary layer, known as Langmuir Circulation (LC), through a series of laboratory experiments. Theories suggest that LC is generated by the interaction of surface wave Stokes drift with sheared flow in the boundary layer. However, no detailed examination of the LC instability theory has been made under controlled conditions. At issue is whether the presently accepted theory can be proven correct in a laboratory setting, and whether it is relevant to oceanic conditions. Successful completion of this project would resolve the first issue and frame appropriate questions for investigation of the second.

OCE 96-33794梅尔维尔 该项目将通过一系列实验室实验，研究表面边界层中相干结构的初步发展，即朗缪尔环流。 理论表明，LC是由表面波斯托克斯漂移与边界层中剪切流的相互作用产生的。然而，没有详细的检查LC不稳定性理论已在受控条件下。 争论的焦点是目前被接受的理论是否可以在实验室环境中被证明是正确的，以及它是否与海洋条件有关。成功完成这一项目将解决第一个问题，并为调查第二个问题提出适当的问题。
