Ocean surface waves mediate the transfer of momentum, heat, and gas across the air-sea interface. Yet there exist very few detailed observations of the role of short ocean wave growth and directionality in mediating these exchanges. This project is to analyze a large set of ocean surface wave, near-surface hydrodynamics, and air-sea momentum flux data collected at the Air-Sea Interaction Tower (ASIT) between late 2019 and early 2020. The proposed work will help to resolve fundamental aspects of the relationship between air-sea momentum flux, ocean surface waves, and near-surface hydrodynamics. The results will be incorporated into classroom material for a new course on physical air-sea interaction at the University of New Hampshire and an existing course at Columbia University. Additionally, the results will be made available to K-12 teachers in the New York City area through the LDEO program "Earth2Class (E2C) Workshops for Educators". The project will quantify the relationship between wind forcing and the directional growth and relaxation of short surface gravity and gravity-capillary waves. The air-sea momentum fluxes will be addressed by combining the observed thermal skin advection and short-wave propagation data with the atmospheric turbulent stress profile and subsurface velocity profile. One of the outcomes of this project will be to produce a new parameterization for the ocean surface current response to wind forcing that incorporates turbulent stress and the ocean surface wave state.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

海面波介导动量，热量和气体在整个空气界面上的转移。然而，很少有关于短海浪生长和方向性在介导这些交流中的作用的详细观察。该项目是为了分析2019年下旬至2020年初在气海相互作用塔（ASIT）收集的大量海面波，近地面流体动力学以及空气动量通量数据。拟议的工作将有助于解决空气动量通量，海洋表面波，海洋水平和近距离水力的基本方面。结果将被纳入教室材料中，以在新罕布什尔大学和哥伦比亚大学现有课程中进行新课程。此外，结果将通过LDEO计划“ Earth2Class（E2C）为教育工作者进行”，向纽约市地区的K-12老师提供结果。该项目将量化风力强迫与方向生长与短表面重力和重力毛细管波的松弛之间的关系。空气动量通量将通过将观察到的热皮肤对流和短波传播数据与大气湍流应力曲线和地下速度曲线相结合来解决。该项目的结果之一将是为海面电流对风力强迫的反应产生新的参数化，并融合了湍流压力和海面波状态。该奖项反映了NSF的法定任务，并被认为值得通过基金会的知识分子优点和更广泛的影响标准通过评估来进行评估。
