Mountain lakes in East Siberia have been studied for recent changes in water chemistry, turbidity and diatom assemblages preserved in bottom sediments. We performed a regional analysis of the relative effect of climate and glacier changes on change in diatom diversity and supply of meltware in proglacial lakes. We analysed sediment records from East Siberian glacier lakes using geochemical and diatoms proxies. We found that dramatic changes in communities and abundance of diatoms and biogenic proxy could be induced by low nutrient concentrations in glacial lakes and high turbidity due to active degradation of glaciers and snow patches as a result of the global increase in temperature in the Northern Hemisphere. Our evidences show that diatoms have been gradually decreased since ca. the 1880s. A significant tendency towards diatom reducing occurred at high summer regional temperatures. This tendency may be attributed to the fact that glaciers and snow patches thawed actively in East Siberia during ca. 1880-1958, which was induced by the beginning of the Recent Warming (ca. 1850-1860) and a long period of relatively warm regional climate from ca. 1900 to 1960.

The paper presents a study of bottom sediments of proglacial Lake Ehoy, which intakes the meltwater of Peretolchin glacier, the East Sayan Ridge. A bottom sediment sequence that formed in the period of 1885-2013 was investigated with a year/season time resolution using X-ray fluorescence with synchrotron radiation and conventional analysis. A depth-age model of the core was based on counting of the annual laminae. The model was checked by an analysis of the distribution of activity of

A 850-year record climate and vegetation changes in East Siberia (Russia), inferred from geochemical and biological proxies of lake sediments

East Siberia is very sensitive to moisture regimes because it is located in a margin area, where moisture from the North Atlantic is strongly depleted, and the penetration of the East Asian monsoon is weak and rare. In winter months, the Siberian anticyclone strongly blocks and reduces the external influences on the region. The high latitude of the study area at 52°N is probably sensitive to variation in insolation and solar activity. We analysed a 42-cm-long sediment record from Lake Mountain located in East Siberia (Russia) for geochemical, mineralogical, subfossil diatoms, chironomids, and pollen to provide a reconstruction of the climate history of the area for the last 850 years. According to our reconstruction, a clear decrease in summer temperatures occurred in East Siberia after ca. 1400 and we linked this temperature drop with the beginning of the Little Ice Age. The coldest summer occurred about ca. 1570-1700 and 1830-1900. We assumed that the most significant changes of the lake bio-productivity and the catchment area were occurred about ca.
