概要

Preliminary glaciological investigation was carried out on the accumulation area of Sofiyskiy Glacier, Russian Altai Mountains in July2000.Analyses of a 12.3m core and 3m deep pit samples show that seasonal variations of δ^<18>O, tritium and melt features remained in the wet snow layers.Annual layer thickness determined on the basis of seasonality of these elements for 12.3 m core is 0.99 m of water on average in 1994-1999 with a minimum in 1998 when the minimum mass balance was observed for three other glaciers in the Altai Mountains.High correlations of NH_4^+ concentration with concentrations of K^+, SO_4^2, NO_3^- and PO_4^<3->are found.NH_4^+ and K^+ are considered to be of biomass burning origin, and PO_4^<3-> and NH_4^+ are due to chemical ingredients used for fire extinction in biomass burning.
