Adaptation to climate change is seen as an economic task, but it is based on the climatic conditions of territories and their expected changes in the medium term. The purpose of this article is to identify relevant approaches to assessing climate risks based on research data and expert assessments, selecting relevant climate variables, and forecasting the expected (probable) level of climate risks using global climate models. The work uses general scientific methods of analysis, synthesis and scientific generalisation. The analysis of existing regulatory and legal documentation in the field of regional adaptation has been carried out, and the limitations of its requirements have been shown, primarily the emphasis on retrospective analysis of risks and a closed list of indicators characterising the level of their danger. One of the main tasks to be solved in the process of adaptation planning is to find a correspondence between risk and climatic variables that determine its probability of realisation and the level of danger. Approaches to determining the list of regional climatic variables, information about which is necessary for planning adaptation measures, within the framework of the climate or sectoral approach, using standard lists of climatic variables and indices, formed by the World Meteorological Organisation, or on the basis of expert consensus, are considered. It is shown that regional climate forecast is one of the main components in solving the problem of adaptation to climate change, and the methods of forecasting and improving the spatial accuracy of such a forecast (statistical and dynamic downscaling) are considered. The proposed methodological approaches are intended for use in the practice of planning regional adaptation measures, including in the territory of the Republic of Sakha (Yakutia), and in updating the Strategy of Socio-Economic Development of the Republic of Sakha (Yakutia).

The article raises the question of the expediency of studying the possibilities of developing heavy oils and bitumen in the upper part of the section in the northwest of the Republic of Sakha (Yakutia). The Siligir-Markhinsky bitumen field is identified as the most promising object byabundance of manifestations and geographical location. Brief information is given on the lithological and stratigraphic section and the main tectonic elements of the study area. Anomalous thickness of the section with negative temperature (up to 1450 m) is indicated as a distinctive feature of the studied territory. The features of the distribution of epigenetic oil and bitumen occurrences along the section and the influence of hypergenesis processes on the individual and group composition of oils and bitumen are presented in detail. It is concluded that the most studied and attractive object for the extraction of heavy oils, malts and asphalts are the rocks of the Markhinskaya and Morkokinskaya suites in the immediate vicinity of the Udachnaya kimberlite pipe. Physicochemical characteristics of oil sand bitumens are given, indicating their mobility in the temperature conditions of the upper part of the section of the region under consideration. It is proposed to use horizontal drilling in combination with multiplicative petrofracturing for the development of oils and bitumens of the Siligir-Markhinsky field. Direct signs of oil and gas contentestablished during testing of exploration well No. 2-P drilled in non-structural conditions are presented. A possible reason for the failure to obtain oil and gas inflows is the poor quality of the opening of productive layers. It is concluded that the prospects for oil and gas content of the Markhinsky arch along the lower part of the section are preserved, taking into account the placement of the exploratory well in non-structural conditions and limited experience in opening oil-bearing strata. It is noted that the necessity of monitoring the stability of gas flow rate with an increased hydrogen content in the area of the Udachnaya pipe to study the possibilities of hydrogen production.

This paper attempts to calculate hydrocarbon reserves in productive formations of the Buyaginskaya deep drilling area. Brief information on the lithologic-stratigraphic section and tectonic structure of the Buyaginskaya structure, which is located in the western part of the Suntar uplift of the Siberian Platform, is given. Zonal and sectional features of the prospective Kharystan Vendian horizon are noted based on the history of the region’s development. The results of well testing in the intervals of occurrence of Kharystan and Osinsk productive horizons are presented. On the basis of the data obtained during the trial operation of the Kharystan productive horizon deposit, the reserves were estimated by the pressure drop method. The conclusion was made about low potential of the Kharystan horizon gas deposit within the studied area. Based on eld geophysical data, the calculation parameters for the Osinsk horizon were substantiated and oil and gas reserves were calculated using the volumetric method. It is shown by calculation that the reserves of the Buyaginskaya area can be classi ed as shallow according to the current reserves classification. The results of prospecting and exploration works in the area of the junction of the Vilyuchanskaya saddle and the Predpatomsky regional trough, showing high prospects of the Kharystan horizon in the regional plan, are presented. On the basis of the conducted studies, it is suggested that the Kharystan horizon may be distributed within the avlacogens, which are narrow and extended negative structures of the crystalline basement of northeastern strike along the northwestern and southeastern slopes of the Suntar uplift. Similar zones of oil and gas accumulation may be developed along the slopes of the Arbaisko-Sinskiy rampart. Alternative ways to monetize the available gas resources of the Buyaginskoye prospective field were proposed.

Cracks in the rock mass significantly affect the physical and mechanical properties of rocks, and they, in turn,must be taken into account in the planning of mining operations and construction of mining structures. There arevarious techniques for detecting cracks in the rock mass using GPR data. However, the application of these techniquesis limited by the productivity of geophysical operators, as the GPR data are mainly interpreted by them manually. Tostudy the fracturing of frozen rocks from GPR data, it is possible to use artificial neural networks (ANN), which willmake it possible to analyze GPR radarograms in order to detect discontinuities and shifts of in-phase axes of GPRsignals. A significant problem in the application of ANN is the preparation of data for training (training sample). It ispossible to create a training data set using a model of GPR section of frozen rock massif with a fracture. However,the practice of using synthetic radarograms based on the model of GPR section of frozen rock massif with a crack hasshown the need for its improvement in terms of increasing the number of rock layers, the possibility of setting inclinedboundaries, taking into account the presence of syn- and antiforms. The article describes the stages of neural networkmodel development, including the creation of a training data set, selection of architecture, training and testing of theneural network model. The validation of the ANN model showed high performance of the ANN model. Nevertheless,some drawbacks are observed in the performance of the model. The developed system will significantly reduce the timecost of GPR data interpretation. Further research will be related to improving the prediction accuracy associated withthe expansion of the training data set and development of an additional ANN model.

The GPR method is used to study the river ice cover, which provides operational information on ice thickness. The obtained data are visualized through the QGIS geoinformation system, which maps the spatial distribution of ice thickness. However, the system has disadvantages due to manual correction of the data. The study proposes the use of software to visualize the results more efficiently. This will help analyze the data more quickly, identifying areas of thick ice and ice-bottom contacts that could be potential obstacles to spring ice drift movement.

This article presents the developed physical and geological models for the GPR method, which is currently actively used in the study of mining and geological and geocryological conditions of developed alluvial deposits in the cryolithozone. The relevance of the development of GPR models is dictated by the need to determine the features of wave fields (radargrams) for reliable data interpretation. Typical models of horizontal layered structure of the upper part of the geological section (frozen loose sediments, including those with inclusion of layer ice, paleorules) of diamondiferous placers in the subarctic zone of Yakutia are considered. Computer modeling was carried out in the gprMax system using the numerical finite difference method in the time domain. Based on its results, the GPR models containing a scheme of the geological section with a description of electrophysical properties and a synthetic radargram were built. Analysis of the results of computer modeling allowed us to determine the features of the radargram structure, parameters of GPR signals in the presence of formation ice, paleorules sections. The results of the studies have shown that the developed GPR models contribute to the improvement of signal processing procedures and the development of data interpretation features in the study of the geological structure and geocryological conditions of alluvial deposits in Yakutia (using the example of “Mayat River” Anabar district) by GPR.

This review-analytical paper presents the current state of GPR studies of river ice cover as one of the promising and alternative directions for spatial coverage of extended river sections. The works of many domestic and foreign researchers are devoted to various aspects of this issue. These aspects touch upon such topics as different methods of conducting both ground-based GPR studies and from an aircraft; processing and interpretation of GPR data, as well as many other topics. In the analytical part of the article, summarizing the results of the works of researchers, it should be concluded that the most accurate and complete data on the condition of the ice cover of rivers were obtained by using GPR with the antenna unit frequency ~ 400 MHz. It is also noted in the work that the issue of determining different forms of ice cover based on the results of GPR data processing is insufficiently studied in the studies.
