Distribution and chemical composition of snow cover of the Sygyktinsky glacier (Kodar Ridge, south eastern Siberia)

Abstract

Snow survey was carried out in the central part of the Sygyktinsky Glacier (Kodar Ridge, south eastern Siberia), and a map of the distribution of snow cover was constructed (average snow thickness was 97 cm). Stratigraphy and the chemical composition of the snow cover were studied in a snow pit. It was established that the chemical composition of the snow belongs to the chloride class, ammonium and sodium groups. At the same time, the ionic composition of snow reflects seasonal changes in atmospheric circulation in the region (local continental sources of ions prevail in winter, while the proportion of marine ions increases in the spring).
