The 21st century is characterized not only by large-scale transformations but also by the speed with which they occur. Transformations—political, economic, social, technological, environmental, and legal-in synergy have always been a catalyst for reactions in society. The field of energy supply, like many others, is extremely susceptible to the external influence of such factors. To a large extent, this applies to remote (especially from the position of energy supply) regions. The authors outline an approach to justifying the development of the Arctic energy infrastructure through an analysis of the demand for the amount of energy consumed and energy sources, taking into account global trends. The methodology is based on scenario modeling of technological demand. It is based on a study of the specific needs of consumers, available technologies, and identified risks. The paper proposes development scenarios and presents a model that takes them into account. Modeling results show that in all scenarios, up to 50% of the energy balance in 2035 will take gas, but the role of carbon-free energy sources will increase. The mathematical model allowed forecasting the demand for energy types by certain types of consumers, which makes it possible to determine the vector of development and stimulation of certain types of resources for energy production in the Arctic. The model enables considering not only the growth but also the decline in demand for certain types of consumers under different scenarios. In addition, authors’ forecasts, through further modernization of the energy sector in the Arctic region, can contribute to the creation of prerequisites that will be stimulating and profitable for the growth of investment in sustainable energy sources to supply consumers. The scientific significance of the work lies in the application of a consistent hybrid modeling approach to forecasting demand for energy resources in the Arctic region. The results of the study are useful in drafting a scenario of regional development, taking into account the Sustainable Development Goals, as well as identifying areas of technology and energy infrastructure stimulation.

Abstract The Arctic is the northernmost region of our planet, including the outskirts of the continents of Eurasia and North America, as well as the corresponding islands and archipelagos, the Arctic Ocean and parts of the Atlantic and Pacific oceans. Despite the still existing discrepancy in the concept of the boundaries of the Arctic region, all researchers agree in one opinion: this region is most sensitive to the climate change, and the consequences may be irreversible. As a part of the commitments on sustainable development undertaken by Russia and taking into account the importance and special status of the Arctic region, it seems necessary to consider the possibility of transforming the energy sector of the Arctic as one of the main sources of emissions of pollutants and CO2 in the region. The combination of energy sources proposed in the article - natural gas and renewable energy sources - is the cleanest and most environmentally friendly, and a hybrid energy system based on this alliance is the most sustainable and allows to use advantages of proposed energy sources, hedging each other's limitations. Proposed hybrid system could contribute to the development of the region and the well-being of its population and the environment.

<p>The existence of seasonal variations in major tides has been recognized since decades. Where Corkan (1934) was the first to describe the seasonal perturbation of the M2 tide, many others have studied seasonal variations in the main tidal constituents since. However, most of these studies are based on sea level observations from tide gauges and are often restricted to coastal and shelf regions. Hence, observed seasonal variations are typically dominated by local processes and the large-scale patterns cannot be clearly distinguished. Moreover, most tide models still perceive tides as annually constant and seasonal variation in tides is ignored in the correction process of satellite altimetry. This results in reduced accuracy of obtained sea level anomalies. </p><p>To gain more insight in the large-scale seasonal variations in tides, we supplemented the clustered and sparsely distributed sea level observations from tide gauges by the wealth of data from satellite altimeters. Although altimeter-derived water levels are being widely used to obtain tidal constants, only few of these implementations consider seasonal variation in tides. For that reason, we have set out to explore the opportunities provided by altimeter data for deriving seasonal modulation of the main tidal constituents. Different methods were implemented and compared for the principal tidal constituents and a range of geographical domains, using data from a selection of satellite altimeters. Specific attention was paid to the Arctic region where seasonal variation in tides was expected to be significant as a result of the seasonal sea ice cycle, yet data availability is particularly limited. Our study demonstrates the potential of satellite altimetry for the quantification of seasonal modulation of tides and suggests the seasonal modulation to be considerable. Already for M2 we observed changes in tidal amplitude of the order of decimeters for the Arctic region, and centimeters for lower latitude regions.</p><p> </p><div>Corkan, R. H. (1934).

The search for a new model of collective security is one of the most important institutional challenges in a multipolar world. Despite the fact that modern processes of regionalization are increasingly determined by cognitive factors, the Arctic region is becoming a macro-region of the world, where the balance of national interest of countries with different economic systems can determine the institutional criteria for future global interaction or confrontation in achieving the goals of sustainable development.

The article analyzes the evolution of China's Arctic policy, which has expanded over three decades from individual polar research to observer status in the Arctic Council and the existence of a state Arctic strategy. China and Russia have established mutually beneficial cooperation in the Arctic region in such conditions, when in many areas there are fundamental contradictions between the countries. The West did not have a long-term strategy capable of responding to current security challenges, including in the Arctic. When Russia tried to regain lost positions on the world stage in 2007-2008, China became an increasingly influential player in the world. If before the Arctic had been outside the lines of rivalry for decades, the question of the Far North as an arena of military competition began to take first place. China has become a long-term threat to both the United States and Russia. In previous years, with the help of the China, Moscow had the opportunity to receive the necessary investments and technologies for large-scale Arctic projects. The more Beijing attempts to establish itself as an influential player in the Arctic, the more the threat to other Arctic countries will grow. The Russian Federation has positioned itself as a leader in the region. The country's policy was aimed at strengthening this status through regional control and expansion of the military presence. This led to a response from the United States and NATO countries. In Russia it was assessed as a threat. The question arises as to what the strategy of the United States should be, and whether it will be possible to resist the costly arms race. If not, then the competition will be concentrated in the political and economic spheres. A particular aspect is the rapid militarization of the Arctic region after 2014, primarily due to changes in Russia's military strategy, which extends to the North. This has led to the tensions between the United States and Russia. China has not yet resorted to expand its military power in the Arctic. China's policy of economic and infrastructural influence is opposed to military methods. The effectiveness of Chinese non-military methods of influence is assessed

We study the level of total electron content (TEC) disturbance in ionospheric mid-latitude and high-latitude regions during 2013. TEC behavior is calculated using data from two GPS stations: MOND (Mondy) and NRIL (Norilsk). TEC variations are calculated from two-frequency phase measurements for all radio rays. We analyze the TEC variations in two time ranges: 10 and 40 min. These ranges correspond to middle- and large-scale ionospheric disturbances respectively. The TEC disturbance level is characterized using the special index WTEC. WTEC allows us to receive multi-day continuous series of average TEC variation intensity. We reveal that at high latitudes WTEC variations agree well with AE ones. The correlation between WTEC and Dst variations is much less. The minimum level of TEC disturbance is independent of the season in the Arctic region; diurnal WTEC variations are more pronounced for medium-scale ionospheric disturbances than for large-scale ones. At mid-latitudes, the WTEC behavior agrees well with the Dst and Kp variations only during strong magnetic storms. The minimum level of TEC disturbance is higher in summer than in winter. At mid-latitudes, the sunset terminator generates gravitational waves. In the Arctic region, terminator-generated waves are not observed.

This article discusses the most significant sources of large-scale radioactive contamination to which the Arctic has been exposed since the middle of the last century, which are identified as 1) radioactive fallout and deposition from nuclear weapon testing; 2) plum waste from the Sellafield radiochemical plant (United Kingdom) and Cap de la Ag (France) nuclear fleet operation; 3) radioisotope thermoelectric generators; and 4) submerged and sunken radioactive objects. The article assesses the comparative contribution and associated radioecological risks of these sources, and special attention is focused on the “nuclear legacy” of the USSR/Russian nuclear fleet and the search for solutions. The article describes the content and implementation results of the “Development of a Strategic Master Plan for Disposition of Decommissioned Russian Nuclear-Powered Fleet and Rehabilitation of Hazardously Radioactive Sites and Facilities of Its Support Infrastructure” which was developed with broad international cooperation. Attention is drawn to remaining environmental problems associated with submerged and sunken objects that contain spent nuclear fuel and radioactive waste in the Arctic, and the article presents generalized data on such objects and associated risks of water contamination as identified by analyses of model studies of possible accident consequences.

Recently, the developments of ethics and politics in the Arctic region have again become an issue for international discussion. One main issue is the problem of climate change and sustainability of the Arctic region. This problem is linked to the issue of exploitation of natural resources in the Arctic region, not at least in Greenland. Indeed, the general issue is how we should define ethics of the environment and sustainability as a general principle for the Arctic region. It is important to discuss what is at stake and how we define the problem in relation to the different participating stakeholders. This paper deals with these problems as a case for global ethics and it proposes a vision of ethical and political responsibility for sustainable development in order to deal with such problems.
