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 accuracy of GHCN-CAMS reanalysis reproduction of the intra-annual air temperature distribution was assessed for the historical (1961-1990) and current (1991-2020) climatic periods, on the scale of climatic norms of seasons and individual months. Data on 86 meteorological stations on the territory of the Sakha Republic (Yakutia), for which climatic series in both time periods were available, were used. The climatic norms of meteorological stations for both periods, as well as their change between periods, were compared with the GHCN- CAMS reanalysis data in corresponding pixels. The root mean square error, Pearson correlation coe cient, and Lin’s concordance coe cient were calculated as similarity metrics. Climatic norms for meteorological stations and calculated in the GHCN-CAMS reanalysis model are closely related linearly, with a correlation coe cient above 0.9, and the highest accuracy is observed for spring months. At the same time, the quality of reanalysis reconstruction of change in climatic norms for months and seasons between periods is signi cantly lower; the best reanalysis accuracy is for fall and winter, and signi cantly lower for summer. In general, the GHCN-CAMS model can be used for calculation and forecasting applications that require intra-annual air temperature distribution.
