OCE 96-33423 Jessup The project will determine the role of microscale wave breaking as a forcing mechanism in air-sea gas transfer. The breaking of very short surface gravity waves without air entrainment, known as microscale breaking, disrupts the diffusive sublayer which governs the flux of gas across the air-sea interface. Thus, microscale breaking has been proposed as a dominant mechanism for gas transfer. This proposal will establish a new approach for the prediction of air-sea gas transfer velocity based on quantitative measures of microscale breaking derived from infrared (IR) imaging techniques in the laboratory.

该项目将确定微尺度波浪破碎作为海气输送强迫机制的作用。在没有空气夹带的情况下，非常短的表面重力波的破裂被称为微尺度破裂，破坏了控制气海界面气体通量的扩散亚层。因此，微尺度断裂被认为是气体传递的主要机制。本文提出了一种基于实验室红外成像技术的微尺度断裂定量测量预测海气输送速度的新方法。
