【摘要】 根据1983年9月至1984年12月4个航次的调查资料,应用非线性最小二乘迭代拟合法,得出南海中部深水中溶解氧和总无机碳的垂直分布模式——稳定态非守恒组分的一维垂直扩散-对流方程KC″-ωC′+J=0;溶解氧和总无机碳的平均拟合方差分别为±0.03ml/kg和±0.02mmol/kg。与它们相应的测量精密度很相近。同时也简要地讨论了调查海区深水中溶解氧和总无机碳之间的相互关系。结果表明,南海中部深水中的平均氧消耗与总无机碳的再生量基本相同。更多还原

【Abstract】 The vertical distribution models of dissolved oxygen and total inorganic carbon, one-dimensional vertical diffusion-advection equations for the stable nonconservative tracers, KC"-ωC’+J = 0, in the deep-water area of the central South China Sea have been derived by using a nonlinear least-squares iterative fitting procedure from the investigation data obtained at four stations during four cruises from September, 1983 to December, 1984. The model can fi the observed data well. The mean fitting square deviations are about ±0.03ml/kg for the dissolved oxygen and ±0.02m mol/kg for the total inorganic carbon. These are nearly equal to the measurement precisions. The total CO2-O2 interrelationships in the deep waters of the studied area have also been investigated. It shows that the mean consumption of oxygen is approximate to the production of total inorganic carbon.更多还原
