Isotopic analysis of the snow cover at an alpine glacier as an indicator of local climatic variations and isotopic homogenization processes
Stratigraphic variations of 18O/16O ratios of winter-accumulated snow at an alpine temperate glacier correspond to temporal pattern of local climatic variations. Although the snow is influenced by percolation and homogenization processes, the isotope stratigraphy in the glacier's accumulation a...

| Summary: | Stratigraphic variations of 18O/16O ratios of winter-accumulated snow at an alpine temperate glacier correspond to temporal pattern of local climatic variations. Although the snow is influenced by percolation and homogenization processes, the isotope stratigraphy in the glacier's accumulation area is not destroyed during the first part of summer. Below the equilibrium line altitude, rapid melting results in isotopic homogenization. Variation of δ 18O values in the firn are relatively small. |
