説明
Hydrogen and oxygen isotope measurements of rain and of snow samples collected from Nagaoka in Niigata pref., Japan, were examined. Their variations of isotopic composition changed considerably within a few days. The rain samples were collected daily from 10/15 to 10/18 during the 10th typhoon of 1998. The snow samples were collected on 2/24 and 2/25 in 1999. Oxygen and hydrogen isotope ratios of the rain and the snow samples were measured with a Micromass PRISM mass spectrometer using an equilibrium technique of carbon dioxide and hydrogen with platinum, respectively.<br>The following two results were obtained:<br>(1) The average values of δD and δ18O of the rain and the snow samples were between -32.5 and -62.9 per mil, and between -7.7 and -9.8 per mil, respectively.<br>(2) The d value calculated using the obtained δD and δ18O were between 2.46 and 22.06 for the rain and between 28.84 and 37.46 for the snow.<br>Surprisingly, the isotopic composition of water precipitated in Japan changed rapidly based on the obtained results. The implication of these results suggests that analyzing isotopic ratios may lead to a prediction of a possible disaster caused by heavy rain or snow.
