Accurate parameterisations of absorption rates of low-solubility gases (e.g. oxygen, carbon dioxide) across open air-water interfaces are important to industry and the environmental sciences, e.g. for estimating carbon dioxide transfer rates in industry and the global environment as well as rates of the re-aeration of nutrient-enriched water. Recent studies show that at open air-water interfaces under moderate wind forcing, absorption rates are primarily determined by microscale wave breaking. This project will determine the dependence of gas flux rates on the scale, strength and intermittency of microscale wave breaking and, by incorporating this key process, produce substantially improved predictive schemes.

低溶解度气体(例如氧气、二氧化碳)在开放的空气-水界面上的吸收速率的准确参数对工业和环境科学非常重要，例如用于估计工业和全球环境中的二氧化碳转移速率以及营养丰富的水的再曝气速率。最近的研究表明，在温和的风强迫下，开放的空气-水界面上的吸收速率主要由微尺度的波破裂决定。该项目将确定气体通量速率与微尺度波破裂的规模、强度和间歇性的相关性，并通过纳入这一关键过程，产生显著改进的预测方案。
