Abstract:

10 m and 2.3 m ice cores were obtained on Austre Brøggerbreen, Spitsbergen in Svalbard (78°53N, 11°56E, 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.
