中文摘要：

一氧化碳（CO）在大气化学中是一种重要的中间化合物,也是一种间接的温室气体,而海洋是大气中CO的源。本研究以中国近海有代表性的陆架海区—东海和黄海为调查区域,于2009年11-12月对其溶解CO的浓度分布以及海-气通量进行了研究。结果表明,东海和黄海表层海水中CO的浓度为0.13-3.30nmol L^-1,平均为0.84±0.54nmol L^-1。CO浓度的垂直分布特征表明,CO浓度最大值一般出现在表层,随深度增加CO浓度逐渐减小。CO在东海和黄海所有调查站位基本都是过饱和的,过饱和系数为0.3-19.8,平均为3.88±2.95,海气通量为0.24-3.10μmol m^-2d^-1,平均为0.84±0.82μmol m^-2d^-1,表明调查期间东海和黄海是大气中CO的源。

英文摘要：

In atmospheric chemistry, carbon monoxide （CO） is an important intermedial compound and an indirect greenhouse gas. The ocean has been known as a source of CO to the atmosphere. In this work, the distributions and sea-to-air flux of CO in the East China Sea （ECS） and the Yellow Sea （YS） during Nov.-Dec. 2009 were studied. The concentrations of CO in the surface water of research area varied from 0.13 to 3.30 nmol L^-1 , with an average of 0. 84-1-0. 54 nmol L^-1. Vertical profiles of the concentrations of CO showed a gradually decreased trend with depth in the water column, with the highest value appearing at the sea surface in general. Concentrations of CO were supersaturated relative to its atmospheric concentrations at all investigated stations in the ECS and the YS, and the supersatu- ration factors ranged from 0. 3 to 19.8 with an average of 3.88 ±2. 95. The sea-to-air fluxes of CO vaired from 0.24 to 3.10 μmol m^-2 d^-1 , with an average of O. 844±0.82μmol m^-2 d^-1.
