Abstract
This paper focuses on field activity by the "Japan-Russia Joint Glaciological Research on Sofiyskiy Glacier, Russian Altai Mountains" carried out during 15 - 24 July 2000 and 6 - 17 July 2001. The purpose of this investigation was to reconstruct climate and environment records in the past few decades through ice core study. Three ice cores 25.1 m, 12.3 m and 9 m deep were recovered and two pits of 3 and 4.5 m deep were made on the accumulation area of Sofiyskiy Glacier (49o47'10"N, 87o43'48"E; 3435m a.s.l.). The deepest 25.1m core will preserve the environmental record during the last 10 to 20 years. Ice core samples were cut and melted at the research site, and transported to Japan for more detailed analyses, such as oxygen isotopes, microparticles, pH, anions, cations and bacteria content. Cores consisted of firn and ice layers. It was found that the borehole temperature was 0oC from the surface to 8m depth and also from 16m to 25m depth. The temperature between 8 and 16m was negative with the minimum at 10 m depth (-0.1oC for the 2000 borehole and -0.3oC for the 2001 borehole). Meteorological observations were also carried out. After the investigation on Sofiyskiy Glacier in 2001, reconnaissance survey of glaciers near the Russia-China-Mongolia border region was carried out and surface snow was sampled at two sites.
