Condition of bottom sediment of Kandry-Kul lake (Bashkortostan) in 2010, 2012

The results of studies of bottom sediments of Kandry-Kul lake in 2010, 2012 are presented. The types of silts and the specificity of their spatial-temporal distribution are revealed. The seasonal changes of the structure of silts are characterized. The water-physical properties, chemical components and their seasonal dynamics are studied. The correlations between the properties of medium and the content of silt components are discussed. The certain relations between depth, temperature, silt moisture, pH, redox potential and the organic matter, content of total and mineral phosphorus, iron, carbonats are defined.
