“…The problem addressed in this note is that, owing to experimental and methodical difhculties, the present observational basis available to estimate oceanatmosphere gas transfer coefficients is limited indeed, so that improvement is called for. Except for reactive (Liss and Slater, 1974) or exceedingly soluble (a > 10, (Miinnnich et al, 1978)) gases (Slinn et al, 1978), the resistance for interfacial gas transfer is concentrated in the laminar sublayer at the water side of the air-water interface (i.e., k x k,). Only the determination of the liquid-phase transfer resistance, k; ', will be considered in the following.…”
