Bioluminescence Imaging of Wave Induced Ocean Turbulence

破碎的海浪在许多近表面过程中是至关重要的，如混合、海流的产生、质量热、动量和气体的通量。该项目将使用生物发光腰鞭毛虫作为响应流体剪切应力的显微传感器，对破碎波峰内随时间变化的流体剪切应力和能量耗散进行定量测量。这些测量将在实验室破碎波中进行，然后将这些测量结果纳入现有的破碎波中空气夹带机制的模型中。 本科生将积极参与实验和数据分析。此外，还计划开展外联活动。

ABSTRACTOCE-0242065Breaking ocean waves are critically important in many near-surface processes sucha as mixing, the generation of currents, the flux of mass heat, momentum and gases. This project will use bioluminescent dinoflagellates as microscopic sensors responsive to fluid shear stress to make quantitative measurements of time-evolving fluid shear stress and energy dissipation inside a breaking wave crest. The measurements will be made in laboratory breaking waves and then these measurements will be incorporated into existing model of air entrainment mechanisms in breaking waves. Undergraduate students will be active participants in the experiments and the data analysis. In addition, outreach activities are planned.
