In a large international study of soil organic carbon in cryogenic soils and upper permafrost, an unprecedented amount of data was analysed, including carbon distribution in more than 2,700 soil profiles.
The analyzed profiles also included data on the content of organic carbon obtained during the study of soils of key sites in the Kolyma Lowland
In the course of an extensive international study of the content of soil organic carbon in cryogenic soils and the upper layer of permafrost, an unprecedented amount of data was analyzed, including the distribution of carbon in more than 2700 soil profiles. The analyzed profiles also included data on the content of organic carbon obtained during the study of soils of key sites in the Kolyma Lowland.
It is well known that the content of organic carbon, as well as the morphological forms of its presence in the profile, directly correlate with the ability of soil material to accumulate various global and local pollutants. Thanks to the use of modern methods of processing remote sensing data and statistical analysis of the material, it was possible to establish the amount of conserved organic carbon, the reserves of which in the upper 100 cm of the soil-permafrost complex are estimated at approximately 510 Pg.
It has been established that the leading factors that ensure carbon accumulation processes in soils and permafrost are soil moisture, altitude above sea level, as well as surface layer temperature and precipitation. The results of the study made it possible to create the first spatial model of interaction between organic carbon accumulation processes and landscape-climatic factors in such a high resolution.
