- Abstract
Water chemistry has been studied in different-order tributaries of the Bureya R. (Far East), taking into account the geoenvironmental processes of organic carbon transformations in the active biosphere layer (seasonally thawing/freezing soils) at the boundary with permafrost. Changes in water chemistry were evaluated with the use of the spectral characteristic of soluble organic substances (SOM) in aqueous extracts of soils from different horizons of the seasonally thawed layer and the activity of microbial complexes with respect to humic substances. Microbial complexes of the active layer and the depth to the permafrost horizon were found to be the governing factors in SOM composition. Experiments showed that, the temperature being the same, the qualitative composition of SOM in watercourses during permafrost thawing can be significantly different.
