Abstract

This paper is devoted to the study of thermodenudation impact on concentration of the organic matter dissolved in lake water. Summarized are results of the laboratory tests on concentration of colored dissolved organic matter in water samples collected out of the lakes in Central Yamal. Analyzed is the diff erence of colored dissolved organic matter concentration in lakes with the coasts aff ected by active thermodenudation and in lakes with undisturbed coasts. Buried peat layers discovered in the thermocirque exposures appeared to have high concentration of dissolved organic carbon. It is established that average concentration of colored dissolved organic matter is 3.5–4.5 times higher in lakes with thermocirques.
