Due to the natural processes and technogenic influences gases from the upper horizons of rocks including conserved in the permafrost released into the atmosphere. Particular attention of researchers is attracted to methane (CH4) as one of the main greenhouse gases. When analyzing the relationship between climate change and greenhouse gas flows, the main problem is the lack or insufficient amount of empirical data on methane content in natural sources, including permafrost and underground ice. In this regard, it is not possible to adequately assess the contribution of a specific region to the overall global methane budget of the atmosphere. For the first time of the study area, the methane content by the depth in the seasonal thawing layer for different types of landscapes was analyzed. The data obtained show that the greatest amount of methane is realized from the landscapes of highly waterlogged lowland areas and flood plains, in contrast to the watershed landscapes with well drained deposits. Based on the map of landscape zoning for the area of the geocryological station Marre-Sale, a preliminary map of the methane content in the seasonal thawing layer for different types of landscapes was constructed. The study is supported by RSF grant № 16-17-00102.
