This article contains data on the nature and level of study of the territories in which the north-eastern part of the Sakha Republic is located, which are potentially oil and gas bearing. In 1979-1992, seismic exploration of oil and gas was carried out in the Tastakh trough, the Zyryanka depression by JSC Yakutskgeofizika. The section of the Tastakh trough includes strata of terrigenous rocks of lithological unconstrained composition. Its capacity is 2.5-4.5 kilometers. The paper describes reflecting horizons based on Neogene-Quaternary, Jurassic-Cretaceous deposits. In addition, during the research, it was found that the Lower Cretaceous sediments present in the Tompon depression are divided by the Tomporuk-Kitchan zone of thrust divisions of the Late Cretaceous stage of activation of the Verkhoyano-Kolyma region. Upper Jurassic volcanogenic sedimentary rocks, Lower Cretaceous coal-bearing deposits are contained in the Zyryanka depression at 6 and 5 thousand meters, respectively. This article contains an opportunity for the allocation of time intervals, interpretation of sedimentary synchronous complexes of deflections, depressions, shelf. Seismic materials in these territories have a quality that can be recycled. The evidence of the need for this procedure appears during discussions on the topic of geological development, the structure of the mountain-folded Verkhoyano-Kolyma region, as well as the shelf that adjoins it. These data are confirmation of the presence of oil and gas in these territories. The work was carried out with the scientific equipment of the Center for Collective Use of the Federal research center ҺYakut Scientific Center of the Siberian Branch of the Russian Academy of Sciencesһ under grant No. 13.TsKP.21.0016. Support was received in the form of funds under the State Assignment from the Ministry of Science and Higher Education of the Russian Federation No. 122011100158-1.

The physical properties of air and water as carriers of thermal energy, used or taken into account in the development of devices and technologies for the use of natural thermal resources, are briefly stated. The developed cooling and heating devices and technologies that use the thermal energy of air and water are presented. It is shown how the change in the design achieved an increase in the reliability of the air thermosiphon used for local cooling of the soils of the foundations of structures. The technology of accumulating cold atmospheric air in an array of frozen soils containing underground structures, which has been successfully used for more than 10 years to control the temperature regime of the Federal Cryostorage of Plant Seeds in Yakutsk, in which only natural cold resources are used for the first time in the world, is given. The technology for creating an underground accumulator of cold atmospheric air by freezing water and using the heat of its phase transition to cool liquids and gases, as well as the results of experimental tests, are described. The efficiency of using the heat of the phase transition of water for heating some types of industrial premises is shown. A method for reducing the buoyant effect of frost heaving of soils on pile foundations by heating freezing heaving soils with the heat of the phase transition of water is described.

One of the ways to obtain information about the cryogenic state of rocks by GPR is based on the analysis of the in-phase axes of signals reflected from local objects. On the images of GPR radargrams, similar in-phase axes are represented by hyperbolic curves. On the basis of their localization and refinement of the form, the speed of passage of an electromagnetic wave in the medium is determined. To refine the shape of the hyperbolic curve in the developed algorithm, methods based on the Hough transform were used. To optimize the performance of the algorithm, restrictions on the dimensions of the original and accumulator spaces are introduced. The boundaries of the original space were determined on the basis of previous studies on the detection of hyperbolic axes of common-mode signals. The dimension of the Hough space was reduced on the basis of a priori knowledge of the possible allowable speed of electromagnetic waves in the medium. As a result of the work of the created software, the speed of propagation of an electromagnetic wave in space above the local object and the real part of the complex relative permittivity are calculated, which makes it possible to determine the electrophysical properties of the medium. Testing of the developed algorithm was carried out on the results of field georadar measurements and synthetic data. The accuracy of the results of the algorithm was 98.6 %, which indicates the adequacy of its applicability for studying ice in permafrost layers.

The Basin of the Vilyui river is located on the territory of Western Yakutia, one of the most developed and industrialized parts of Yakutia, which is of great economic and strategic importance for Russia. The region is the center of the diamond mining industry of the Russian Federation, where primary and alluvial diamond deposits are developed, a cascade of hydroelectric power stations is located on the river Vilyui. This causes environmental and social problems, negatively affecting all components of the natural environment. It is necessary to study the stability of northern landscapes to technogenic impact and study the hydrobiological state of aquatic ecosystems, in particular, the state of the algoflora of watercourses. As a result of studying the degree of stability of landscapes in the basin of the river Vilyui to technogenic impact on permafrost and bioclimatic indicators, the degree of their resistance is determined. It was revealed that, according to the permafrost characteristics, the northern taiga open forest and haze landscapes are defined as predominantly weakly resistant, the middle taiga as medium resistant. The most unstable in terms of bioclimatic indicators were mountain-tundra landscapes, characterized by the coldest and most humid conditions. As a result of studies of the current hydrobiological state of the rivers in the basin of the river Vilyui determined the low development of phytoplankton and phytoperiphyton in the river Irelyakh, M. Botuobuya and in the upper reaches of the river Vilyui, consisting of a monotonous species composition of diatoms and green algae. The maximum average number of algae varies from 82290 cells/l to 20700 cells/l, the highest biomass was noted in one area and is 1.58 mg/l. The Shannon-Weaver biodiversity index varies by sampling points along the river. Vilyuy from 0.19 bits / copy. and 1.00 bits/copy. up to 2.40 bits/copy. According to the sanitary-biological characteristics, mass species-indicators of water saprobicity were identified, which indicates the III class of water purity, as moderately polluted. Thus, it was determined that the state of phytoplankton and phytoperiphyton is under the influence of the technogenic load of diamond mining and hydropower enterprises.The work was carried out according to the state assignment on the topic “Vegetation cover of the permafrost zone of the taiga Yakutia: biodiversity, habitat-forming functions, protection and rational use” (scientific topic code: FWRS-2021-0023; draft state task (No. FWRS-2021-0014) of the program in the priority area of the PFNI RF for the long-term period (2021-2030).
