摘要 于2006年4月至2007年1月对桑沟湾海域进行了4个航次的调查,采集表层海水样品,研究了该海域表层海水中溶解N2O的分布特征及海气交换通量的季节变化,结果表明:桑沟湾表层海水中溶解N2O浓度和饱和度存在一定的季节性变化,浓度表现为冬季最高而饱和度为夏季最高。利用Liss和Merlivat公式(LM86)以及Wanninkhof公式(W92)估算了该海湾海水中N2O的年平均海-气交换通量,分别为0.2μmol/(m2.d)±0.1μmol/(m2.d)和1.5μmol/(m2.d)±1.0μmol/(m2.d)。 Distributions and fluxes of N2O are determined during four surveys on Sanggou Bay between 2006 and 2007. The results show an obvious seasonal variation with the highest concentration occurring in winter and the highest saturation occurring in summer. Liss and Merlivat relationship (LM86) and Wanninkhof relationship (W92) are employed to estimate the average sea-to-air N2O fluxes. The results show that N2O fluxes from Sanggou Bay are 0.2 μmol/(m^2·d)±0. 1 μmol/(m^2·d) and 1.5 μmol/(m^2·d) ± 1.0 μmol/(m^2·d) by LM86 and W92, respectively.
