In this article we present the results of landscape structure study in the Middle Lena valley (Erkeni, Ensieli and Tuimaada), made using GIS mapping based on Sentinel 2 satellite images andASTER GDEM datasets. Alas complexes and croplands were identi ed using K-means image segmentation with di erent initial numbers. Three machine learning algorithms were tested for pixel-based land cover classi cation. The best result was achieved with the Support Vector Machine classi er. The mapping revealed the landscape structure of 20 spatial units, which were organized into groups of upland, alas, slope, valley and oodplain landscapes. The contrasting landscape structure of the Middle Lena valley was revealed. The northern Ensieli valley is characterized by the predominance of forest larch-pine landscapes, alas complexes mostly dry with steppe meadows are widespread in the watershed. The slopes are dominated by larch forests with patches of birch. The central Tuimaada valley is the most anthropogenically transformed, here steppe meadows and anthropogenic steppes dominate. The plateau part is mainly forested with croplands. The southern valley of the Erkeni is characterized by the smallest area of the valley part dominated by steppe meadows, the slopes of the main bank of the southern and south-eastern exposition are covered with xerophytic meadows. The landscape structure of valleys, oodplain and plakor parts largely determines the speci cs of agricultural land use of the local population. The results obtained can be used for further research into the response of permafrost landscapes of the Middle Lena valleys to increased anthropogenic pressure in the context of climate change.

In this article the problem of studying the landscape structure of inaccessible territories is considered on the example of the neighbourhood of Lake Labynkyr in the Republic of Sakha (Yakutia). The characteristic features of the nature of the unique Lake Labynkyr are highlighted and described. From the position of landscape structure differentiation vegetation indices are analysed. The result of using NDVI (Normalised Difference Vegetation Index), TVI (Transformed Vegetation Index), NRVI (Normalised Ratio Vegetation Index), MTVI2 (Modified Triangular Vegetation Index - improved), MSAVI2 (Modified Soil Corrected Vegetation Index - 2) is presented. The methodology used is based on the experience of studies of areas of similar inaccessibility and uses the raster calculator of QGIS software in combination with slope steepness data obtained from the digital model. Particular attention is paid to the features of the relief, as it is one of the leading factors in the formation of the type of terrain. Characteristic features of five terrain types of the study area are identified and described: slope deluvial-solifluctional, slope deluvial-colluvial, moraine (foothill moraine), mountain-valley, glacial-valley. Based on the analysis of the collected field material, as well as the use of remote sensing methods and geoinformation technologies, the spatial organisation of landscapes was revealed and a map scheme was presented.

The materials of reports and publications on the seismogeological characteristics of the Anabar-Olenek structural zone, the shelves of the Laptev Sea and the East Siberian Sea have been studied. The work performed is aimed at clarifying, detailing and increasing the reliability of further research, previously updated in the process of scientific study of geological exploration materials of past years. The geological factors affecting the distribution of average and interval velocities of seismic reflection waves in the sedimentary cover are considered. For the entire territory, researchers have established an increase in reservoir and average velocities in the sedimentary cover as its thickness increases. This dependence is typical for the continental part of the platform. In the shelf deposits of the northern seas of Yakutia, the velocity dependence is determined by tectonic and magmatic factors, which become decisive for the Gakkel Ridge, Hyperborea, and the Novosibirsk-Chukotka structural zone. In the western part of the Laptev Sea, the surface of the consolidated crust corresponds to the surface of the Archean-Lower Proterozoic crystalline basement. In the rest of the territory, in the wave seismic field, the foundation is the asynchronous acoustic boundary of the surface of metamorphosed and dislocated strata with an age interval from the Riphean to the Paleogene. The observed complex wave pattern and various options for seismic reflector binding, in the opinion of the authors, are largely due to the structural and tectonic features of the evolution and interaction of the Siberian platform, Hyperborea, the Verkhoyansk-Kolyma folded region, the Arctic plume, the Novosibirsk-Chukotka structural-tectonic zone. The work was carried out with financial support within the framework of the state assignment of the Ministry of Science and Higher Education of the Russian Federation No. 122011100158-1 using the scientific equipment of the Center for Shared Use of the Federal Research Center ҺThe Yakut Scientific Centre of the Siberian Branch of the Russian Academy of Sciencesһ within the framework of grant No. 13.TsKP.21.0016.
