The dynamics of mountain geosystems in southern Siberia

Tracing recent glacial events in bottom sediments of a glacial lake (East Sayan Ridge, Russia) from high‐resolution SR‐XRF, ICP‐MS, and FTIR records

“…Namely this fine material increased the turbidity of the lake water that led to a decrease in the bio‐productivity. Similar alternations of ‘mobile’ and ‘stationary’ states of glaciers are also observed in other mountain regions of Eastern Siberia …”

“…Those are 1897-1906, 1963, 1982, and 2006-2008. [13,14,50,51,54,55] According to these observations, the bottom bound of the glacier was lowest (Fig. 6).…”

“…In whole, the period of 1938-1970 is characterized by the high summer temperatures, which caused a substantial reduction in the glacier volume and essential approaching of its borders. Field observations in 1982 showed that the bottom border of the glacier was about 42 m lower than in 1963 [51] . From our data, the rate of the glacier retreat decreased significantly in 1970-1980, which is because of a significant lowering in summer air temperatures (refer to Fig.…”

“…Similar alternations of 'mobile' and 'stationary' states of glaciers are also observed in other mountain regions of Eastern Siberia. [51][52][53] Currently, there are four chronological 'slices' for which the edges of Peretolchin glacier were instrumentally measured. Those are 1897-1906, 1963, 1982, and 2006-2008.…”

Fragilidade Ambiental E Dinâmica Geossistêmica: Mapeamento Da Paisagem Na Bacia Hidrográfica Do Rio Lourenço Velho, Sul Do Estado De Minas Gerais-Brasil

“…Nas primeiras duas décadas do século XXI, o avanço dos métodos computacionais de análises de imagens de satélite com possibilidade de monitoramento ambiental, ofertou a possibilidade a novas contribuições no âmbito dos estudos sobre a evolução e dinâmica dos sistemas físicos-naturais dispostos e organizados na superfície, com destaque para os trabalhos de Isachenko (2007) ;Plyusnin et. al.…”
