A careful analysis of upper ocean field data collected during two cruises (1995 and 1997) funded under the Coastal Ocean Process (CoOP) program will be conducted to estimate air-sea gas exchanges. A focus of the investigation will be on the interactive role that atmospheric forcing and surfactants play generating and damping small waves and near-surface turbulence, and how the modification of these processes affects the transfer velocity and therefore the turbulent gas flux. The expected outcome of the analyses is an improved parameterization of the air-sea gas transfer velocity which incorporates all the relevant physical and chemical processes, and is applicable to wide range of environmental conditions.

将对沿海海洋过程方案资助的两次巡航（1995年和1997年）期间收集的上层海洋场数据进行仔细分析，以估计空气-海洋气体交换。研究的重点将是大气强迫和表面活性剂在产生和抑制小波和近地表湍流中所起的相互作用，以及这些过程的改变如何影响传递速度，从而影响湍流气体通量。分析的预期结果是一种改进的海气传递速度参数化，它包含了所有相关的物理和化学过程，并适用于广泛的环境条件。
