内容記述 |
δ^<18>O and major ions of the snow surface layer were measured during hoarfrost formation. In the nighttime, δ^<18>O decreased when surface hoar and depth hoar crystals formed above and beneath the snow surface, respectively, while δ^<18>O increased due to evaporation in the daytime. These results suggested that H_2^<16>O was enriched by condensation of the hoar crystals, whereas H_2^<18>O was concentrated on the snow surface by the evaporation of light H_2O to the atmosphere. Concentrations of major ions were observed to change as well according to condensation and evaporation of water vapor. δ^<18>O of hoar crystals condensed on March 5 to 6 was estimated to be approximately 5‰ lower than that of the original surface layer. |
