Stratigraphy and ice grains of a 25.3m ice core from Sofiyskiy Glacier, Russian Altai Mountains, in 2001
This paper focuses on results of visual stratigraphy and ice grain analysis of a 25.3m ice core from Sofiyskiy Glacier, Russian Altai Mountains, recovered in July 2001. It was found that the ice core consists of firn, icy granular firn, ice layer, infiltration-recrystalization ice and infiltration i...
