Аннотация: Boreal permafrost soils store large amounts of organic carbon (OC). Parts of this carbon (C) might be black carbon (BC) generated during vegetation fires. Rising temperature and permafrost degradation is expected to have different consequences for OC and BC, because BC is considered to be a refractory subfraction of soil organic matter. To get some insight into stocks, variability, and characteristics of BC in permafrost soils, we estimated the benzene polycarboxylic acid (BPCA) method-specific composition and storage of BC, i.e. BPCA-BC, in a 0.44 km(2)-sized catchment at the forest tundra ecotone in northern Siberia. Furthermore, we assessed the BPCA-BC export with the stream draining the catchment. The catchment is composed of various landscape units with south-southwest (SSW) exposed mineral soils characterized by thick active layer or lacking permafrost, north-northeast (NNE) faced mineral soils with thin active layer, and permafrost-affected raised bogs in plateau positions showing in part thermokarst formation. There were indications of vegetation fires at all landscape units. BC was ubiquitous in the catchment soils and BPCA-BC amounted to 0.6-3.0% of OC. This corresponded to a BC storage of 22-3440 g m(-2). The relative contribution of BPCA-BC to OC, as well as the absolute stocks of BPCA-BC were largest in the intact bogs with a shallow active layer followed by mineral soils of the NNE aspects. In both landscape units, a large proportion of BPCA-BC was stored within the permafrost. In contrast, mineral soils with thick active layer or lacking permafrost and organic soils subjected to thermokarst formation stored less BPCA-BC. Permafrost is, hence, not only a crucial factor in the storage of OC but also of BC. In the stream water BPCA-BC amounted on an average to 3.9% of OC, and a yearly export of 0.10 g BPCA-BC m(-2) was calculated, most of it occurring during the period of snow melt with dominance of surface flow. This suggests that BC mobility in dissolved and colloidal phase is an important pathway of BC export from the catchment. Such a transport mechanism may explain the high BC concentrations found in sediments of the Arctic Ocean.

Аннотация: [1] The oxygen isotope ratio of ice cores and sea-sediments is an extremely useful source of information on long-term climatic changes. A similar approach has been applied to the oxygen isotope ratio of tree rings to enable a pattern-based reconstruction of the isotope variations on the continents. We present an oxygen isotope map for northern Eurasia spanning from Norway to Siberia, that reflects the isotope distribution in the late 19th century, and compare it with an equivalent map for the present-day situation. The average isotope values of 130 trees show a large east-to-west gradient and are highly correlated with the isotope distribution of precipitation. Surprisingly, the (18)O/(16)O ratio of the wood has been decreasing in the interior of the continent since the late 19th century, in contrast to the strong temperature increase recorded by meteorological data. From this isotope trend over time a change in the seasonality of precipitation can be inferred.

Аннотация: Reconstruction of climate change in Central Asia over the last millennium with an annual resolution was made using geochemical and biological proxy in lake bottom sediments and tree-ring data. We investigated the lake in Central Asia- Teletskoe (Altai), Kucherla (Altai), Baikal, Arahlei (Chita) - and adjacent areas. Cores of bottom sediments were investigated by method of scanning X-ray fluorescent analysis with synchrotron radiation with the spatial resolution of 0.1 mm. It corresponds to the time resolution ~ 0.2-0.5 year. At each point analyzed more than 30 trace elements from K to U. Geochemical proxy of terrigenous, organogenous and aerosol components of sediments well correlated with regional meteodata for the last 100-150 years. Time series of lithological-geochemical indicators of climate change based on dating by 14C, 137Cs and 210Pb was calibrated by instrumental hydrometeorological data. We used tree-ring series together with element contents as an additional proxy for calculation of transfer function, considering that tree-ring series are response to summer temperature in this climatic zone. Annual temperature and precipitation change for the Central Asia region (0 - 1000 years ago) have been reconstructed using the transfer functions such as: time series proxy=function (temperature, precipitation).

Аннотация: The study was done to determine concentrations of radionuclides and heavy metals and to evaluate the frequency of chromosomal aberrations in samples of Elodea canadensis, a submerged plant, collected in different parts of the Yenisei River. Samples were collected in the area subjected to radioactive impact of theMining-and-Chemical Combine (MCC) at Zheleznogorsk and in the control areas, upstream of the MCC. The investigations showed that Elodea biomass in the area affected by MCC operation contained a long inventory of artificial radionuclides typical of the MCC discharges. Upstream of the MCC, in the control sampling areas, the sediments and the Elodea biomass contained only one artificial radionuclide - 137Cs. Thus, the exposure doses to Elodea shoots and roots upstream of the MCC are small (not more than 8 ?Gy/d) and the main contribution to them is made by natural radionuclides. At the MCC discharge site (the village of Atamanovo) and downstream of it, the total dose rate increases almost an order of magnitude, reaching its maximal values - 72 ?Gy/d for Elodea shoots and 58 ? Gy/d for roots. Cytogenetic investigations of Elodea roots showed that at the MCC discharge site (the village of Atamanovo) and downstream of it the occurrence of chromosomal aberrations in ana-telophase and metaphase cells of Elodea was considerably higher than in the control area. It is highly probable that this simultaneous dramatic increase in the total exposure rate and the occurrence of chromosomal aberrations in Elodea is associated with the radiation factor. It is suggested that Elodea is affected not only by the radiation factor but also by the chemical factor - toxicity of heavy metals. В© 2009 EDP Sciences.

Аннотация: The method analytical microstratigraphy of lacustrine sediments allows to obtain paleoclimatic information fundamentally new quality was tested on a model object - Lake Teletskoe (Gorny Altai). Teletskoe lake bottom sediments were studied by scanning X-ray microprobe using synchrotron radiation from VEPP-3 (INP SB RAS, Novosibirsk) with an annual time resolution on the time interval of 1500 years. Data on the distribution of isotopes Cs-137, Pb-210, C-14 were used to create an age model: core depth - age. Using this model were constructed time series of sediment cores composition changes. To obtain the time series used a scanning X-ray analysis on synchrotron radiation with 100 micron spatial resolution. At each point of the core at the same time determines the content of more than 20 trace elements: K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Ga, As, Se, Br, Rb, Sr, Y, Zr, Nb, Mo, Ba, Pb, Th, U. Terrigenous elements (Ti, V, Cr, Rb, Y, Th) reflect changes in precipitation in the catchment. Organogenic elements (Br, Zn, U) are more associated with regional temperature changes. The ratio of Rb/Sr shows the size of the particles and associated with spring flooding dynamics. The resulting time series were processed by mathematical methods, including the Hilbert-Huang transformation. Was found a set of cyclical changes in litho-geochemical indicators in the Lake Teletskoe sediments with periods of 3.5±0.3; 8.8±0.9; 18.9±2.0; 37.8±1.6; 86±10; 164±15; 346±30; 596±71 and 993 years. Found cycles can be used to predict climate change in nearest decades. © SGEM2013 All Rights Reserved by the International Multidisciplinary Scientific GeoConference SGEM.

Аннотация: A solar-terrestrial relations were examined using millennium-scale paleoclimatic data from the Central Asia mountain region. The paleoclimatic data were based on nonvarved lake sediments of the Teletskoye lake and temperature-sensitive long tree-ring width chronologies from the Altai region (Altai Mountains, South Siberia, Russia) in the late Holocene (2000 years). Also a solar-activity during late Holocene was used to analyze. Core of the bottom sediments from the Teletskoe lake (Altai Mountains) were investigated using scanning X-ray fluorescent analysis method with synchrotron radiation (spatial resolution is 0.1 mm). A method ensemble empirical mode decomposition (EEMD) was used to extract low-frequency variability from all presented paleoarchives. The results obtained for paleodata indicate palaeoclimatic oscillations in the range of the de Vries (Suess) (?200-year) solar cycles through the late Holocene. Evidence of the influence of solar activity on global climatic processes and terrestrial ecosystems is discussed.

Аннотация: At present, the genesis, nomenclature, and classification of granuzems remain debatable, which is explained by scarce data on these soils. In this paper, data on granuzems described in the forest-tundra of the Norilsk depression, in the valleys of the Tukalanda, Akkit, and Khantaika rivers (68 degrees 30 ' N, 88 degrees 15 ' E) and in the northern taiga within the lower reaches of the Nizhnyaya Tunguska River (66 degrees 20 ' N, 89 degrees 00 ' E) are discussed. Genetic and geographic features of granuzems are closely related to the mineralogy and texture of their parent materials represented by moraine and glaciofluvial loamy and clayey sediments derived from quartz-containing dolerites. Granuzems are characterized by the strongly acid or acid to neutral reaction and, accordingly, by the low base saturation in the upper horizons and moderate base saturation in the lower horizons. Granuzems are characterized by the elevated content of humus of the fulvate composition (C-ha/C-fa < 1) and by the high content of oxalate-extractable iron. The main soil-forming processes are weathering and aggregation of the coagulative cryochemogenic nature. The horizon with strong rounded-grain or crumb-granular structure serves as a diagnostic horizon of granuzems. The surface litter horizon may have different thickness and decomposition degree.
