摘要
Variations of 180 in the snow which accumulates at a Nordic temperate glacier during the winterare not entirely eliminated after a few months of ablation in the following summer. Survive of isotopicsignals closely relates to the re-freezing capacity of snow accumulated in winter when its temperature wasbelow 0 .C. The melt-water re-freezing ice layers formed in winter hindered subsequent melt-water percolationin summer when snow temperature was at melting point and. therefore. varied isotopic record wasreserved between these ice layers.
