Abstract
Atmospheric oxygen has been found to be enriched in oxygen-18 by 23.5 +/- 0.3 per mil relative to average ocean water (SMOW). Oxygen dissolved in seawater is further enriched in oxygen-18 by 0.85 per mil at 0 degrees C. The temperature dependence of the solubility enrichment is given by epsilon (per mil) = 0.85- 0.010 t ( degrees C). This result is in good agreement with earlier measurements of the solubility effect in distilled water.
摘要
大气中的氧相对于平均海水（SMOW）的氧-18 丰度增加了 23.5 +/- 0.3 per mil。在 0°C 时，溶解在海水中的氧进一步增加了 0.85 per mil 的氧-18。溶解度富集的温度依赖性由 epsilon（per mil）= 0.85-0.010 t（摄氏度）给出。这一结果与早期对蒸馏水溶解度效应的测量结果吻合良好。
