Near-Inertial Oscillations (NIO) in the coastal ocean may play a significant role in vertical mixing and horizontal dispersionof nutrients and particles in the eastern Gulf of Mexico, particularly on the West Florida Shelf (WFS). There is evidence that on the WFS the depth of the thermocline appears to migrate vertically over the course of a day, suggestive that a NIO mode structure may be modulating the thermocline depth and possibly affecting the distribution of biota across the thermocline, making the NIO potentially important to the coastal ocean ecology on the WFS. This award will support a Postdoctoral Fellow to investigate the dynamics of NIO on the WFS. The Fellow will work at the College of Marine Science at the University of South Florida (USF-CMS) with the sponsorship of Dr. Robert H. Weisberg, and in the Center for Ocean-Atmospheric Prediction Studies at the Florida State University (FSU-COAPS) with the co-sponsorship of Dr. Dmitry Dukhovskoy.She will also mentor a summer undergraduate student through the Florida-Georgia Louis Stokes Alliance for Minority Participation (LS-AMP) at FSU, develop a physical oceanography lab to add to a set of bio-geochemical labs for the Oceanography Camp for Girls and contribute physical oceanography questions for the Spoonbill Ocean Sciences Bowl.The PI will investigate the kinematics of NIO on the West Florida Shelf (WFS) with a full documentation of their spatial and temporal variations. This will be followed by a thorough investigation of the dynamics of the processes, particularly, how turbulence and bottom stress enter into the force balances and affect the conditions and mechanisms of generation of NIO in the region. Finally, the role of near-inertial motions in mixing on the WFS will be assessed.

近惯性振荡（NIO）对墨西哥湾东部，特别是西佛罗里达陆架（WFS）的营养盐和颗粒的垂直混合和水平扩散有重要作用。 有证据表明，在WFS上，温跃层的深度似乎在一天的过程中垂直迁移，这表明NIO模式结构可能正在调节温跃层的深度，并可能影响整个温跃层的生物群分布，使NIO对WFS上的沿海海洋生态具有潜在的重要性。该奖项将支持博士后研究员调查NIO在WFS上的动态。该研究员将在南佛罗里达大学海洋科学学院工作，由Robert H. Weisberg和佛罗里达州立大学海洋大气预测研究中心的研究人员Dmitry Dukhovskoy博士的共同赞助。她还将通过佛罗里达州-乔治亚州路易斯斯托克斯少数民族参与联盟（LS-AMP）指导一名暑期本科生，建立一个物理海洋学实验室，地球化学实验室的海洋学营的女孩和贡献物理海洋学问题的琵鹭海洋科学碗。PI将调查的运动学NIO在西佛罗里达大陆架（WFS），并提供其空间和时间变化的完整文件。接下来将对这些过程的动力学进行深入研究，特别是湍流和底应力如何进入力平衡并影响该地区NIO生成的条件和机制。最后，近惯性运动在WFS上混合的作用将被评估。
