  1. Geochemical parameters and element contents in a peat section of the Kyzyltun (Bokarevskii) ryam bog

    Larina, N S; Larin, S I; Moiseenko, Tatyana I
    The paper reports geochemical parameters of units in a peat bed from a raised bog in the southern Tyumen territory. Based on radiocarbon dates and variability of geochemical data the following four evolutionary stages of the bed in Holocene are distinguished: an ancient lake (5600-5750 years B.P.), lowland-bog peat (4550-5600 years B.P.), transitional-type peat (4200-4550 years B.P.), raised-bog peat. The major-component technique was applied to analyze relations between various parameters of the bed and evaluate variations in conditions, under which the bog evolved with time, including climatic conditions (in relative units). An anthropogenic signal of accumulation of certain metals in...

  17. (Table 1) Types of White Sea surface layer bottom sediments and concentration of heavy minerals in 0.1-0.05 mm grain size fraction

    Gusakova, A I
    Mineral composition of recent bottom sediments was studied in the White Sea. A single terrigenous-mineralogical province is defined; it is characterized by a mineral association of amphibole, epidote, garnet, and pyroxene. Five regions are assigned in the White Sea in accordance with mineral composition of surface bottom sediments. We argue that granite-metamorphic rock complexes of the Baltic Shield are the main source of recent bottom sediments in the White Sea, while the East European Craton (Russian Platform) plays the secondary role.

  19. Phytoplankton in the surface desalted lens of the Kara Sea

    Sukhanova, Irina N; Flint, Mikhail V; Sergeeva, V M
    Phytoplankton of a surface strongly desalinated water lens was investigated on the basis of materials collected during Cruise 57 of R/V Akademik Mstislav Keldysh in September 2007. The lens with salinity <18 psu had area of ca. 19000 sq. km and was located in the northwestern part of the Kara Sea near the eastern coast of Novaya Zemlya. It was a specific biotope that had been isolated from surrounding waters for more than three months. In the investigated area 66 algae species were identified. The maximal species diversity was found in the upper layers of the desalinated lens, where species...
