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°C. The temperature dependence of the solubility enrichment is given by ε (per mil) = 0.85— 0.010 t (°C). This result is in good agreement with earlier measurements of the solubility effect in distilled water.Keywords
