Abstract
1 Simultaneously collected rain samples from 3 stations in the Alps (altitude difference 1680 m) show that the evaporation from falling drops causes an isotopic altitude effect of ?0.2‰ per 100 m. 2 Despite the lack of altitude effect in Alpine snow fall, the summer melting and the wind erosion cause distinct isotopic variations in the net-accumulated material on Kesselwandferner. 3 These variations are reflected in the ice in the ablation zone, and they may be used for studying glacier flow patterns.
