Compositional Diversity

The unique and very large PGE–Cu–Ni Noril’sk deposits are located within the Siberian trap province, posing a number of questions about the relationship between the ore-forming process and the magmatism that produced the traps. A successful answer to these questions could greatly increase the possibility of discovering new deposits in flood basalt provinces elsewhere. In this contribution, we present new data on volcanic stratigraphy and geochemistry of the magmatic rocks in the key regions of the Siberian trap province (Noril’sk, Taimyr, Maymecha-Kotuy, Kulyumber, Lower Tunguska and Angara) and analyze the structure of the north part of the province. The magmatic rocks of the Arctic zone are characterized by variable MgO (3.6–37.2 wt %) and TiO2 (0.8–3.9 wt %) contents, Gd/Yb (1.4–6.3) and La/Sm (2.0–10.4) ratios, and a large range of isotopic compositions. The intrusions in the center of the Tunguska syneclise and Angara syncline have much less variable compositions and correspond to a “typical trap” with MgO of 5.6–7.2 wt %, TiO2 of 1.0–1.6 wt %, Gd/Yb ratio of 1.4–1.6 and La/Sm ratio of 2.0–3.5. This compositional diversity of magmas in the Arctic zone is consistent with their emplacement within the paleo-rift zones. Ore-bearing intrusions (the Noril’sk 1, Talnakh, Kharaelakh) are deep-situated in the Igarka-Noril’sk rift zone, which has three branches, namely the Bolsheavamsky, Dyupkunsky, and Lower Tunguska, that are prospected for discovering new deposits. One possible explanation for the specific position of the PGE–Cu–Ni deposits is accumulation of sulfides in these long-lived zones from the Neoproterozoic to the Mesozoic era during magmatic and metamorphic processes. Thus, trap magmatism, itself, does not produce large deposits, but mobilizes earlier formed sulfide segregations in addition carrying metals in the original magmas. These deposits are the results of several successive magmatic events, in which emplacement of the traps was the final event.

For a long time, the Arctic was considered a territory not adapted for human life (“dead earth”), impassable either by water or by land due to the climate. Currently, not only scientists, but also ordinary travelers and tourists are going to the North Pole. Today, tourism in the Arctic is one of the rapidly developing areas in the past few years. Therefore, the authors studied the development of tourism in the Arctic and its impact on the environment. It has been established that the development of ecological, cultural, scientific, extreme tourism, sport hunting, fishing and cruises is relevant for the Arctic regions. It was determined that the main problem in the development of tourism in the Russian Arctic is the transport and logistics underdevelopment of the region. But, these territories are so rich in natural, cultural, historical resources that there is the possibility of developing almost all types of tourism.

Public Health Protection

This paper analyses environmental factors and their influence on the human body in the Far North. The cold factor is considered separately. It is noted that adaptation to extreme environmental factors in the north resembles adaptive processes taking place in the body under stress. The article describes the phenotypic approach to preventing non-communicable diseases in the population based on the theory of adaptation, control theory, theory of functional systems and system approach. We suggest using a predictive model of the body in the form of an anatomico-physiological structure reflecting grouping of interacting organs and tissues by their physiological functions. The model is represented by the reaction norms of the body’s systems and by the rules of their interaction. With its help, one can identify the predisposition of the body’s systems to destruction and the corresponding cause-and-effect relationships in the body, as well as devise a personal algorithm for health preservation and carry out vocational selection. The predictive properties of the model are based on the manifestations of the adaptive response to environmental stress factors. The recommendations are preventive in nature and are aimed at stimulating the individual’s involvement in his/her health protection. Methods of influencing the homeostatic regulation of the body and increasing the capabilities of the immune system in the north are proposed, i.e. technologies for restoring the body’s circadian rhythm as well as activating the living environment and drinking water in order to prevent chronic non-infectious diseases. The suggested predictive model of the body contributes to the development of a general theory of adaptation and a general theory of pathology. The considered approach to health preservation is compatible with telemedicine and e-health technologies and can therefore make adequate medical services available to the population of the Far North, in particular to those living in remote areas.

In 2021, the Russian Federation will assume the chairmanship of the Arctic Council. This fact confirms the special attention of the country’s leadership to the unique geostrategic region. In December 2020, President of the Russian Federation Vladimir Putin, at an online meeting with volunteers and finalists of the contest “Volunteer of Russia”, noted that Russia would grow with the Arctic and the territories of the North. Many Russian citizens’ lives and the state’s success in the international arena depend on this territory’s development. One of the most important mechanisms for achieving the stated goals is national projects (NP), which should make a significant contribution to the development of the country’s territory. The purpose of the study is to assess NP in the subjects that are entirely related to the Arctic zone: Murmansk region, Nenets Autonomous okrug (NAO), Yamalo-Nenets Autonomous okrug (YANAO), and Chukotka Autonomous okrug (CHAO). In the course of the work, general scientific research methods were applied: comparative analysis, data comparison, induction, deduction, etc. The study results showed that, despite all the differences in economic and geographical position, financial condition, population, and regional development priorities, all Arctic regions have similar problems that hinder the effective development of territories. Without solving the problems indicated in the work, it is impossible to expect a qualitative «breakthrough» and implement the NP’s goals.

Living in adverse climatic and geographical conditions of the Arctic zone of the Russian Federation requires mobilization of the adaptive mechanisms of the central nervous system in humans. The parameters of the event-related potential P300 serve as indicators of brain bioelectric processes associated with the mechanisms of information perception and processing. This study aimed to establish the parameters of the event-related potential P300 in 16–17-year-old schoolchildren living in different regions of the Arctic zone of the Russian Federation based on a comparative analysis. The auditory event-related potential P300 was evaluated in subjects living in the Nenets Autonomus Okrug (NAO), Yamalo-Nenets Autonomous Okrug (YNAO) and the Arkhangelsk Region (AR). P300 latency and amplitude were recorded by the Encephalan-131-03 electroencephalograph (Medicom MTD, Russia) in the frontal (F3, F4), central (C4, C3), parietal (P3, P4), mid-temporal (T3, T4), and anterior temporal (F7, F8) areas of the brain using the oddball method. In schoolchildren living in AR and YNAO, the amplitude-latency parameters of P300 did not differ significantly. Subjects living in NAO, the majority of whom are representatives of the indigenous peoples of the North (the Nenets), had a longer P300 latency than their peers from other regions. Р300 amplitudes in schoolchildren from all the regions under study were statistically identical. The author comes to the conclusion that longer information processing time, according to the P300 data, reflects the adaptive psychophysiological characteristics of the population with a long historical experience of living in the North.

The similarity of the regions of the Russian Arctic and the state of Alaska in the United States in the climate, geographical and geopolitical terms is obvious. However, at the same time there are many differences, in many ways determining the level and quality of life of the population of these territories. The historical retrospective of the development of Siberian and northern lands development by the Russian people, who reached the strait between Asia and America and colonized part of the territory of North America, about the successful beginning and end of this "company" stretching for two centuries, some understanding of the need to develop new lands for the Russian man individually and the state as a whole, the article refers. Considering the situation of modern Russia and the United States of America in terms of the sustainable development of the northern, Arctic regions of both countries, an attempt is made to find possible ways to improve the financial situation of the indigenous peoples of the North and the non-native inhabitants of the Arctic zone of the Russian Federation by comparing constitutional approaches to socio-economic development and the area of environmental management of the Russian and American Arctic.

Media Texts

The article presents the results of a study of online information resources that form the modern media image of the Arctic. Using a random sample, 25 online media were selected for analysis, of which five groups of information resources were identified. According to the keywords “Arctic”, “Northern Territories”, “Arctic Zone of Russia”, a database has been formed that includes 500 media texts. Based on their analysis, we tried to answer the questions about what is becoming the dominant media image of the Arctic formed by means of Arctic journalism at the present time, how balanced it is and how it meets the challenges of the time and state interests. The territorial features of the distribution of media texts in the regions of the Arctic zone of Russia are revealed. In terms of their absolute number, the Murmansk Region and the Yamalo-Nenets Autonomous District are the leaders, and in terms of the number of publications per 10,000 people of the population—the Republic of Komi, or rather, the Vorkuta city district, the only one in this subject of the Russian Federation that is part of the Arctic zone of Russia. The most and least frequently encountered topics of media texts are identified. Among the first are publications on the topic of the Arctic raw material potential (32 %), among the second—publications on social topics (6 %). Despite the diversity of media content and the availability of publications on such topics as housing and social security, quality of life, tourism, education, culture and traditions of the peoples of the North, the frequency of publications on social topics in the general flow is extremely low. It is concluded that the potential of this topic is currently not sufficiently disclosed in modern Arctic journalism.
