There is a need to quantify the way climate change is impacting the carbon dioxide exchange dynamics across the ocean-atmosphere interface. Surface waves affect these processes, and in particular, the effect of nearshore waves and white caps together with sprays and bubbles is not understood sufficiently. A more complete understanding requires long-term uninterrupted CO2 flux measurements at multiple locations. To enable these measurements, this project would utilize theory and at-sea measurements to investigate an unexplored energy source based on the nonlinear interaction of nearshore surface waves with the seafloor. The project would involve a high-school student volunteer, a paid undergraduate senior from an under-represented community, and another undergraduate volunteer. Student work would culminate in properly acknowledged posters and videos that will be available through the University’s web site and the students’ social media sites.This research would lead to an energy converter on the seafloor at depths at which first-order dynamic pressure under surface waves is small, but second-order pressure due to resonant nonlinear interaction of surface waves with the seafloor is significant. At full realization, the energy converter-sensor would enable improved (i.e., long-term and uninterrupted) monitoring of the effect of nearshore waves on the CO2 exchange across the ocean surface.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.

有必要量化气候变化影响跨大气界面的二氧化碳交换动力学的方式。表面波影响这些过程，尤其是近海波和白色帽以及喷雾剂和气泡的影响不正确。更完整的理解需要多个位置的长期不间断的二氧化碳通量测量。为了实现这些测量，该项目将利用理论和AT-SEA测量结果来研究基于近岸表面波与海底的非线性相互作用的意外能源。该项目将涉及一名高中生志愿者，来自代表性不足社区的有偿大学生和另一位本科志愿者。学生的工作将最终达到通知的海报和视频，这些海报和视频将通过大学的网站和学生的社交媒体网站可用。这项研究将导致在地板上的一阶动态压力在地面上的一阶动态压力在地面波动下是小而二阶压力，但由于表面波动与Seafoer的表面波动相互作用而引起的一阶压力。充分意识到，能量转换器传感器将能够改善（即长期和不间断的）监测近海波对跨海面的二氧化碳交换的影响。该奖项反映了NSF的法定任务，并已通过评估基金会的智力和更广泛的影响来诚实地认为，通过评估诚实的支持。
