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对海洋-大气界面二氧化碳交换动态的影响方式。表面波影响这些过程，特别是，近岸波和白色帽与喷雾和气泡一起的影响还没有得到充分的理解。更全面的了解需要在多个地点进行长期不间断的CO2通量测量。为了进行这些测量，该项目将利用理论和海上测量，根据近岸表面波与海底的非线性相互作用，调查一种未开发的能源。该项目将涉及一名高中生志愿者，一名来自代表性不足的社区的有偿本科高年级学生，以及另一名本科生志愿者。学生们的工作最终将在适当承认的海报和视频，将通过大学的网站和学生的社交媒体网站提供。这项研究将导致在海底深处的能量转换器，在这个深度，表面波下的一阶动态压力很小，但由于表面波与海底的共振非线性相互作用引起的二阶压力很大。在完全实现时，能量转换器-传感器将能够实现改进的（即，该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
