| Abstract: | 10 m and 2.3 m ice cores were obtained on Austre Brøggerbreen, Spitsbergen in Svalbard (78°53 ' N, 11°56 ' E, 450 m a.s.l.) in September 1994 and in March 1995, respectively. Stratigraphy, bulk density, pH, electrical conductivity, and major ions were obtained from the core samples.
The chemical effect of meltwater percolation through snow/ice is examined. Good correlation between Cl? and Na+ was obtained. The ratio of Cl? to Na+ was 1.14 which was nearly the same value as in bulk sea water. However, the variation of Cl?/Na+ shows that higher ratio occured in the bubble-free ice. Furthermore the Cl? ions remain in higher concentration than SO 4 2? or Na+ ions. |
