我们首次报道了两次北大西洋巡航在开阔海洋上同时测量二氧化碳和二甲基硫化物(DMS)的涡旋协方差通量。在施密特数归一化后，在2-10ms−1的风速范围内，两种气体的气体传递系数和风速依赖关系基本相同。数据表明，气体传递系数与平均风速之间存在线性关系，测得的气体传递系数略高于Wanninkhof(1992年)的参数化值，特别是在低风速时。
We report the first simultaneous eddy covariance flux measurements of CO2 and dimethylsulfide (DMS) over the open ocean for two North Atlantic cruises. After normalization for Schmidt number, the two gases give essentially identical gas transfer coefficients and wind speed dependences for the wind speed range 2–10 ms−1. The data indicate a linear relationship between the gas transfer coefficient and mean wind speed, with measured gas transfer coefficients slightly above the Wanninkhof (1992) parameterization, particularly at low wind speeds.
