Sources of Organic Matter in the Bottom Sedimentsof Small Rivers Estuaries in Basin of the Tatar Strait
The distribution of organic matter, hydrocarbons, phytopigments and ecological-trophic groups of bacteriobenthos was investigated in the bottom sediments of the internal estuaries of the small rivers Muchke and Toki. The morphological and hydrological characteristics of estuaries influenced on quantitative and qualitative composition of the organic matter in bottom sediments. Investigation of the molecular and group composition of n-alkanes in bottom sediments identified the main genetic types of organic matter closely associated with the specific hydrodynamics of waters and sedimentation in small tidal estuaries.
