PI: JessupProposal Number: 9911320Funds are provided for a combination laboratory and field study of the role of microbreaking in air-sea gas exchange. Microbreaking involves the breaking of small waves without the entrainment of air into the water. The resulting turbulence disrupts the thin skin layer near the sea surface, bringing deeper fluid in contact with the air-sea interface. The gas transfer velocity has been observed to correlate with the fractional area of the sea surface associated with microbreaking as well as with the mean squared sea surface slope. This effort is designed to understand the mechanisms behind the relationship between the gas transfer velocity and fractional area of microbreaking and to determine if the relationship of gas transfer velocity to mean squared slope is determined by microbreaking. It is anticipated that this will allow development of a theoretical framework associating gas exchange and microbreaking. Such a theoretical relationship would be of use in air quality prediction and global change and climate studies.

PI：JessupProposal编号：9911320 Funds用于微破裂在海-气交换中的作用的实验室和野外相结合的研究。微破碎是指在不将空气卷进水中的情况下，使小波破碎。由此产生的湍流破坏了靠近海面的薄皮肤层，使更深的流体接触到海气界面。观察到气体传输速度与与微破裂有关的海面分数面积以及海面坡度的均方相关。这项工作旨在了解气体传递速度与微破碎分数面积之间的关系背后的机理，并确定气体传递速度与均方斜率的关系是否由微破碎决定。预计这将允许发展一种将气体交换和微破裂联系起来的理论框架。这种理论关系将在空气质量预测、全球变化和气候研究中使用。
