Determination of Deuterium‐Hydrogen Ratios in Hawaiian Waters

Previous determinations of the deuterium-hydrogen ratios in natural waters revealed the fractionation of deuterium; a fractionation resulting from differences in the vapor pressure of H 2 O and HDO. Measurements of the deuterium in sea, rain, and condensate waters of Hawaii, are reported here. These results show a concentration of deuterium in sea-surface waters, and an inverse relationship of D with altitude in rain and condensate taken on a mountain side. The possible significance of these measurements for cloud physics studies is briefly discussed. DOI: 10.1111/j.2153-3490.1957.tb01917.x
