通过对海洋化学数据的反褶积，表明海洋中O2利用与磷酸盐产生的比值为175±6（而不是Redfield等人（1963）提出的138）。我们没有发现任何证据表明这一比例随海洋位置或深度而显著变化。我们已经使用这个新的比例来计算初始磷酸盐浓度的沃茨采样期间的GEOSECS和TTO计划。这些新结果的重要应用是在约束的起源和流动模式的深沃茨在海洋中。我们认为，可以提出一个强有力的理由，即南极洲盐度最高的水（即，蒙哥马利（1958）的普通水）是由从印度洋、太平洋和大西洋的中深度进入南极的沃茨与威德尔海底层水（南部成分）混合而成的。南极共有水由大约45%的威德尔海底层水、30%来自太平洋和印度洋的中间沃茨和25%来自北方大西洋的深层水组成。
Through the deconvolution of ocean chemical data it has been shown that the ratio of O2utilization to phosphate production in the sea is 175±6 (rather than 138, as proposed by Redfield et al. (1963)). We find no evidence that this ratio changes significantly with location or depth in the sea. We have used this new ratio to calculate the initial phosphate concentrations for the waters sampled during the GEOSECS and TTO programs. The important application of these new results is in constraining the origin and flow patterns of deep waters in the ocean. We believe that a strong case can be made that Antarctic salinity maximum water (i.e., the common water of Montgomery (1958)) is produced by the mixing of waters entering the Antarctic from mid‐depths in the Indian, Pacific, and Atlantic with Weddell Sea bottom water (southern component). Antarctic common water consists of about 45% Weddell Sea bottom water, 30% intermediate waters from the Pacific and Indian oceans, and 25% deep water originating from the northern Atlantic.
