实验在法国马赛LUMINY实验室的IRPHE-IOA的大型海气相互作用模拟隧道中进行，旨在提高我们对破碎波对气体传递影响的理解，并提供传递速度的参数化。详细研究了水和空气中的破波现象、气泡和湍流，以及各种物理性质气体（CO2、CH4、N2O、DMS、CH3Br、4He和SF6）的交换速率。空气-水传递速度与摩擦速度和施密特数的简单标度在高风速下失效。气泡对转移速度的溶解度依赖性增强只能部分解释这种行为。“界面阻力”模型可以解释高风速下的许多突出行为。气泡介导的转移、湍流和表面气泡造成的表面破坏以及界面阻力，都被认为是大风和海况下海气交换的重要因素。
Experiments were undertaken in the Large Air Sea Interaction Simulation Tunnel of IRPHE-IOA, Laboratoire de LUMINY, in Marseille, France, aimed at improving our understanding of the effects of breaking waves on gas transfer, and providing parameterisations for the transfer velocities. Detailed studies were made of breaking wave phenomena, bubbles and turbulence in water and air, and exchange rates of gases with a variety of physical properties (CO2, CH4, N2O, DMS, CH3Br, 4He and SF6). A simple scaling of air-water transfer velocities with friction velocity and Schmidt number breaks down at high wind speeds. A solubility-dependent enhancement of transfer velocity by bubbles can explain only part of the behaviour. An "interfacial resistance" model can explain much of the outstanding behaviour at high wind speeds. Bubble-mediated transfer, surface disruption by turbulence and surfacing bubbles, and interfacial resistance, are all identified as significant to air-sea gas exchange at high wind and sea states.
