标准化为恒定盐度（S）被广泛用于调整海洋无机碳化学数据，如总碱度（AT）和总溶解无机碳（CT）。这种方法可以追溯到海洋化学的最早研究，但忽略了河流输入的碱度和海洋中生物碳酸盐溶解的影响。我们测试了不同的调整的可能性，并得出结论，在大多数地区的海洋表面的归一化概念并不反映代表现实的关系。在本文中，我们提出了一个盐度调整的基础上，一个恒定的和区域特定的S = 0，它表示河流径流，从下面的溶跃层，钙化，和横向海面水交换上升。归一化概念的一个应用是其扩展到AT以及模型中的CT预测和实现。我们给这样的扩展的使用进行了简要的讨论。
Normalization to a constant salinity (S) is widely used for the adjustment of marine inorganic carbon chemistry data such as total alkalinity (AT) and total dissolved inorganic carbon (CT). This procedure traces back to the earliest studies in marine chemistry, but ignores the influence of riverine input of alkalinity and of dissolution of biogenic carbonates in the ocean. We tested different adjustment possibilities for AT and conclude that in most parts of the surface ocean the normalization concept does not reflect relationships which represent reality. In this paper, we propose a salinity adjustment based on a constant and region‐specific term for S = 0, which expresses river run off, upwelling from below the lysocline, calcification, and lateral sea surface water exchange. One application of the normalization concept is its extension to AT and also CT predictions and implementation in models. We give a brief discussion on the usage of such extensions.
