Collaborative Research: EAGER: Energy for persistent sensing of carbon dioxide under near shore waves.

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。面波影响这些过程，尤其是近岸波和白帽以及喷雾和气泡的影响还没有得到充分的了解。要更全面地了解，需要在多个地点进行长期不间断的二氧化碳通量测量。为了能够进行这些测量，该项目将利用理论和海上测量，以近岸表面波与海底的非线性相互作用为基础，调查一种尚未探索的能源。该项目将包括一名高中生志愿者，一名来自代表性不足社区的有偿本科生大四学生，以及另一名本科生志愿者。这项研究将导致在海底深处建立能量转换器，在那里，表面波作用下的一阶动压力很小，但由于表面波与海底的共振非线性相互作用而产生的二阶压力很大。在完全实现时，能量转换器-传感器将能够改进(即，长期和不间断地)监测近岸波对大洋表面二氧化碳交换的影响。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

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.
