ABSTRACTOCE-0623679Surface waves, especially breaking ones, are perhaps the most visually obvious aspect of air-sea interaction. These interactions affect the fluxes of energy, momentum and materials between the air and the sea. Despite their importance, most of our knowledge of these surface wave processes comes from inferences from laboratory data. In this innovative proposal, scientists at Scripps Institute of Oceanography will develop an instrument to measure, for the first time, the flow under naturally-occuring waves which or either breaking (through spilling or plunging) and non-breaking waves. These data will provide unique tests of theories regarding wave-current interactions. They also will provide intriguing images of the flow structures under waves which should be attractive in engaging the public's interest in the scientific study of the nearshore ocean.

表面波，尤其是破碎波，也许是海气相互作用中最直观的方面。这些相互作用影响着空气和海洋之间的能量、动量和物质的流动。尽管它们很重要，我们对这些表面波过程的大部分知识都来自实验室数据的推论。在这项创新的提议中，斯克里普斯海洋学研究所的科学家们将开发一种仪器，首次测量自然发生的波浪下的水流，这些波浪或破碎（通过溢出或暴跌）和非破碎波浪。这些数据将为波流相互作用的理论提供独特的测试。它们还将提供波浪下流动结构的有趣图像，这应该是吸引公众对近岸海洋科学研究的兴趣。
