Abstract. Mobilization of dissolved organic carbon (DOC) and related trace elements (TEs) from the frozen peat to surface waters in permafrost zone is expected enhance under ongoing thaw active layer thickness (ALT) deepening high-latitude regions. The interstitial soil solutions are efficient tracers bio-geochemical processes critical can help decipher intensity metals migration rivers further ocean. To this end, we collected, across a 640 km latitudinal transect sporadic continuous western...
Abstract. The Siberian forest is a tremendous repository of terrestrial organic carbon (C), which may increase owing to climate change, potential increases in ecosystem productivity and hence C sequestration. Phosphorus (P) availability could limit the sequestration potential, but tree roots mine soil deep access mineral P. Improved understanding quantification processes controlling P surface layers ecosystems are thus required. objectives present study were (1) evaluate status horizons from...
The West Siberian Plain stands out among other boreal plains by phenomenal bogging, which has both global and regional significance. polygonal bogs, frozen raised-mound ombrotrophic ridge-hollow raised bogs are the most extensive bog types in study area. These commonly show highly diverse surface patterns consisting of mounds, polygons, ridges, hollows, fens that correspond to microtopes. Here we investigated how microtopographic features landscape affect thermal hydrologic conditions soil...
Abstract The thawing and subsequent decomposition of large stocks soil organic carbon (SOC) currently stored in the northern circumpolar permafrost region are projected to result a ‘positive’ feedback on global warming. magnitude this can only be assessed with improved knowledge about total size geographic distribution SOC pool. This study investigates storage an under-sampled mountain area Russian High Altai. from 39 pits upscaled using GIS-based land cover classification. We found that top...
Thermokarst lakes in the Western Siberian Lowland (WSL) are major environmental factors controlling organic carbon and trace metal storage inland waters greenhouse gas emissions to atmosphere. In contrast previously published research devoted lake hydrochemistry, hydrobiology, sedimentary carbon, processes total dissolved (<0.45 μm) solute composition, colloidal forms of (ОC), related elements remain poorly known, especially across permafrost gradient this environmentally important...
The inland aquatic ecosystems play a significant role in the global carbon cycle, owing to metabolism of terrestrially derived organic matter as it moves through fluvial networks along water continuum. During this transport, dissolved (DOM) is microbial processed and released into atmosphere, but degree intensity processing vary greatly both spatially temporally. Western Siberian Lowlands particular interest for quantitative assessment DOM biodegradation potential because areal-scale effects...
<p>The content and the profile distribution of element composition 1 meter high peat deposits in flat frost mound bogs are investigated. The botanical is described. results analysis showed that consist mainly sphagnum mosses, lichens, shrubs, green pine wood, as well birch bark. A good correlation between degree decomposition brightness dry measured by CIE L*a*b* color model revealed. As a result study samples’ color, it has been found this parameter can be used an express method for...
Abstract The properties and elemental composition of the Histosols polygonal frozen bog in Western Siberia are characterized. study peat soils allowed an evaluation effect micro-landscape on main major element concentrations. According to acid-base characteristics ash content, studied can be qualified as oligotrophic. soil profile shows a tendency increase TOC lower horizons, especially, polygons. highest average TOC, Ca, Mg, K, P, Fe, Na concentrations observed polygons (1.2-2.2 times). A...
The carbon (C) cycle in inland waters, including concentrations and dioxide (CO2) emissions from water surfaces, are at the forefront of biogeochemical studies, especially regions strongly impacted by ongoing climate change. Towards a better understanding C storage, transport emission Central Asian mountain regions, an area knowledge that has been extremely poorly studied until now, here, we carried out systematic measurements dissolved CO2 rivers lakes located along macrotransect various...
Особенности почвообразования и пространственного распространения почв высокогорных склонов Юго-Восточного АлтаяПолучены данные, характеризующие закономерности распространения, строения свойств отрога Курайского хребта Алтая.Важным фактором развития в условиях резко континентального сухого, зимой холодного летом иногда знойного климата является солнечная инсоляция.Неоднородность прогревания вызывает инверсию распространении почвенных типов формаций растительности.Так, установлено, что на...

Abstract. The Russian boreal forest, which mainly consists of extensive forests in Siberia, is the largest continuous forest region on Earth and represents 70 % world's forest. Siberian a tremendous repository terrestrial organic carbon (C), may increase owing to climate change, potential increases ecosystem productivity hence C sequestration. Phosphorus (P) availability could limit sequestration potential, but tree roots mine soil deeper access mineral P. Improved understanding...
