将海洋模型中获得的 32Si/SiO2 比率的计算结果与作为 GEOSECS 计划一部分的该比率的测量结果进行比较（Somayajulu 等人，1987 年，1991 年）。发现一个重大差异；虽然模型预测大西洋深海的比率比太平洋和印度洋深海的比率高三到五倍，但在测量中没有看到这种差异。这表明测量中存在缺陷。我们的建模结果表明，这种半衰期 120 年的宇宙成因同位素最有趣的应用是作为上升流的监测器。然而，考虑到与 32Si 测量相关的费用和难度，此类研究可能被证明是不切实际的。
Calculations of the 32Si/SiO2 ratio obtained in ocean models are compared with measurements of this ratio made as part of the GEOSECS program (Somayajulu et al., 1987, 1991). A major difference is found; while the models predict threefold to fivefold higher ratios in the deep Atlantic Ocean than in the deep Pacific and Indian oceans, no such difference is seen in the measurements. This points to a flaw in the measurements. Our modeling results suggest that the most interesting application for this 120-year half-life cosmogenic isotope is as a monitor of upwelling. However, considering the expense and difficulty associated with 32Si measurements, such studies may prove impractical.
