An Air-Sea Interaction Buoy for High Winds

PI提议建造、装备和测试海气相互作用浮标，以在强风条件下进行近地表海气相互作用测量。具体而言，浮标将配备测量湍流通量的动量，潜热，感热，和二氧化碳沿着平均气象，辐射通量表面波，和水质量的数量。还将研究喷雾和气泡传感器的结合。浮标将被设计为在南大洋等大风/海浪环境中自主运行1年。更广泛的影响这项工作的结果将允许在南大洋全年测量海气通量。这有可能大大提高我们对海气热量和气体交换的理解。即使是有限数量的大风事件的现场测量的可用性将大大提高我们利用全球卫星观测估计海气交换的能力。该项目将培养一名研究生，并为本科生提供研究机会。

The PI proposes to build, equip and test an air-sea interaction buoy to conduct near-surface air-sea interaction measurements in high wind conditions. Specifically, the buoy will be equipped to measure the turbulent fluxes of momentum, latent heat, sensible heat, and carbon dioxide along with mean meteorology, radiative fluxes surface waves, and water mass quantities. The incorporation of spray and bubble sensors will also be investigated. The buoy will be designed to operate autonomously for a period of 1 year in a high wind/wave environment such as the Southern Ocean. Broader ImpactsThe results from this work will allow air-sea fluxes to be measured year-round in the Southern Ocean. This has the potential to improve our understanding of air-sea heat and gas exchanges substantially. The availability of in situ measurements from even a limited number of high wind events will substantially improve our ability to estimate air-sea exchanges using global satellite observations. The project will train a graduate student and will offer research opportunities to undergraduates.
