胶州湾海水微表层粘度及其在海-气通量计算中的作用

The Viscosity of Sea Surface Microlayer in the Jiaozhou Bay and the Effect on the Flux of Chemical Species Between Air and Sea

物质海 -气通量计算新建议中将物质海 -气通量计算公式 F=K(CL- b Cg)中的 CL 用CL ( SML ) 代替。本文着重于对公式中质量迁移系数 K的讨论。在测定了海水微表层、次表层水粘度并同时测定了其它一些化学参量基础上 ,得出如下结论 :海水粘度与盐度、碱度有一定相关性 ;微表层与次表层海水的粘度变化小于 3%。因此 ,海水微表层效应影响 K值 ,与海水微表层效应影响物质浓度相比 ,可以不考虑。

C L was substituted for C L (SUL) in the calculation formula for the flux of chemical species between air and sea in 'the new advice for the flux of chemical species between air and sea'. In this paper the measurement of the viscosity of seawater (sea surface microlayer and subsurface layer) is reported for the first time in the literature and the mass transfer coefficient ' K ' is discussed. The correlation between the viscosity of seawater and salinity and alkalinity is positive. The viscosity of sea surface microlayer is 2%～3% higher than that of subsurface layer. Thus the effect of sea surface microlayer on the value of K should not be discussed in contrast to the effect on the value of the concentration for chemical species.
