    In order to find out a prospecting technique of Khubsugul basin, general conditions of phosphate formation are marked and described. They exhibit a complex of sedimentary environments, making some kind of major deposits' formation model. Factors affecting a phosphate concentrating are examined. A new high - efficiency and ecologically harmless microbiological beneficiating method is proposed for consideration.Для Ρ€Π°Π·Ρ€Π°Π±ΠΎΡ‚ΠΊΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄ΠΈΠΊΠΈ поисков мСстороТдСний Окино-Π₯ΡƒΠ±ΡΡƒΠ³ΡƒΠ»ΡŒΡΠΊΠΎΠ³ΠΎ бассСйна Π²Ρ‹Π΄Π΅Π»Π΅Π½Ρ‹ ΠΈ ΠΎΡ…Π°Ρ€Π°ΠΊΡ‚Π΅Ρ€ΠΈΠ·ΠΎΠ²Π°Π½Ρ‹ основныС условия фосфоритообразования, ΠΎΡ‚Ρ€Π°ΠΆΠ°ΡŽΡ‰ΠΈΠ΅ комплСкс обстановок, ΠΈΠ· ΠΊΠΎΡ‚ΠΎΡ€Ρ‹Ρ… складываСтся своСобразная модСль формирования ΠΊΡ€ΡƒΠΏΠ½Ρ‹Ρ… мСстороТдСний.

The definitive version was published in Journal of Geophysical Research 112 (2007): G04S54, doi:10.1029/2006JG000353.Dramatic changes have been observed in the Arctic over the last century. Many of these involve the storage and cycling of fresh water. On land, precipitation and river discharge, lake abundance and size, glacier area and volume, soil moisture, and a variety of permafrost characteristics have changed. In the ocean, sea ice thickness and areal coverage have decreased and water mass circulation patterns have shifted, changing freshwater pathways and sea ice cover dynamics. Precipitation onto the ocean surface has also changed. Such changes are expected to continue, and perhaps accelerate, in the coming century, enhanced by complex feedbacks between the oceanic, atmospheric, and terrestrial freshwater systems. Change to the arctic freshwater system heralds changes for our global physical and ecological environment as well as human activities in the Arctic. In this paper we review observed changes in the arctic freshwater system over the last century in terrestrial, atmospheric, and oceanic systems.The authors gratefully acknowledge the National Science Foundation (NSF) for funding this synthesis work.

    Water resources of the Russian rivers and their changes

    No full text
    This paper is a review of the recent investigations related to changes in river water resources of the Russian Federation performed at the State Hydrological Institute (SHI). The long-term water resources fluctuations and their changes during the last decades including the significant changes in seasonal runoff are presented. The preliminary estimates of the possible future changes are also given
