标准化至恒定盐度 (S) 广泛用于调整海洋无机碳化学数据，例如总碱度 (AT) 和总溶解无机碳 (CT)。这一过程可以追溯到海洋化学的最早研究，但忽略了河流碱度输入和海洋中生物碳酸盐溶解的影响。我们测试了 AT 的不同调整可能性，并得出结论，在海洋表层的大部分地区，标准化概念并不反映代表现实的关系。在本文中，我们提出了基于 S = 0 的常数和特定区域术语的盐度调整，该术语表示河流径流、溶斜线下方的上升流、钙化和横向海表水交换。归一化概念的一个应用是将其扩展到 AT 以及 CT 预测和模型中的实现。我们简要讨论此类扩展的用法。
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.
