摘  要：
选择山东俚岛湾大型藻类养殖水域作为研究区域,根据2011年4、8、10月和2012年1月4个航次的大面调查获得的pH、总碱度(TA)、叶绿素a等基础数据,分析了该区域表层海水溶解无机碳(DIC)体系各分量的浓度、组成比例及时空变化特征,估算了海-气界面CO2的交换通量。结果表明,该区域表层海水DIC、HCO-3、CO2-3及CO2的年平均浓度分别为2024.8±147.0、1842.4±132.1、170.0±42.8和12.4±2.5μmol/L。养殖区与非养殖区之间DIC、HCO-3浓度差异不显著(P>0.05),而CO2浓度差异极显著(P<0.01)。表层海水pCO2和海-气界面CO2的交换通量的年平均值分别为287.8±37.9μatm和-32.7±17.2mmol/m2.d,养殖区与非养殖区之间、不同季节之间均差异极显著(P<0.01)。大型藻类的养殖活动有利于海洋对大气CO2的吸收。

摘  要：
In order to assess the effect of seaweed aquaculture on sea-air CO2flux,a large-scale seaweed aquaculture area which is located in Lidao Bay,was selected as the investigation area.Based on the investigation data of pH,total alkalinity(TA),Chl-a,etc.during four cruises from April 2011to January 2012,the spatial and seasonal variations of dissolved inorganic carbon(DIC)system parameters and aqueous pCO2were investigated.Results showed that the mean annual concentrations of DIC,HCO3,CO23 and CO2were2024.8±147.0 μ mol/L,1 842.4±132.1 μ mol/L,170.0±42.8 μ mol/L and 12.4±2.5 μ mol/L,respectively.There were no significant differences between areas in concentrations of DIC and HCO 3(P>0.05),while the differences for the concentration of CO2were highly significant(P<0.01).The mean annual values of aqueous pCO2and sea-air CO2flux were 287.8±37.9 μ atm and-32.7±17.2 μ mol/m2.d,respectively.There were highly significant differences(P< 0.01)for aqueous pCO2and sea-air CO2flux not only between different areas,but also between different seasons.Seaweed aquaculture is helpful for the diffusion of CO2across the sea-air interface.
