The Impact

Researchers at the Seismological Laboratory of the Institute of Geodynamics and Geology of the Federal Center for Integrated Arctic Research of the Russian Academy of Sciences (FCIARctic) have been engaged in the seismological monitoring of the European Arctic sector since 2011. In this paper, we present a comparative assessment of the earthquakes spatial distribution in this region based on the data from the International Seismological Centre (ISC) and the FCIARctic’s Arkhangelsk Seismic Network (ASN) obtained in 2012–2016. The paper presents the waveforms of earthquakes occurred at the Gakkel Ridge and the Svalbard archipelago processed with the use of a Russian software package WSG (Windows Seismic Grafer) recommended by the Unified Geophysical Service of the Russian Academy of Sciences. A standard 4–8 Hz bandpass filter was used for the processing of regional Arctic earthquakes. The impact of seasonal variations on the quality of earthquakes registration was analysed based on the seismograms recorded by the ASN’s island-based Arctic stations from 2012 to 2014 The same analysis was done for the central broadband sensor SPA0 of the Norwegian NORSAR-owned SPITS group installed at the Svalbard archipelago. A correlation has been established between the number of earthquakes recorded by the ASN’s island Arctic stations and SPA0 station. The number of regional earthquakes, recorded by ASN’s island Arctic stations is is smaller in summer-autumn periods than in winter periods. Forthe SPA0 station, which is part of SPITS group, there is not seasonality in the number of registered earthquakes. Generally, earthquakes are recorded uniformly, exception on January. This might be due to the increased seismic activity in the Svalbard archipelago during that period.

On the basis of a wide range of sources, the research analyzes the history of the study of permafrost in the territory of the European Northeast of Russia in the first half of the 20th century. The documentary sources revealed in the Archive of the Russian Academy of Sciences (Moscow), the National Archive of the Komi Republic (Syktyvkar), the Scientific Archive of the Komi Science Center of the Ural Branch of the Russian Academy of Sciences (Syktyvkar), the Vorkuta Museum and Exhibition Center (Vorkuta) are introduced into the scientific use for the first time. The 1920s became the period of the birth of a new scientific direction – permafrostology. This science gave an impetus to the systematic study and development of the North and the Arctic. The beginning of systematic geocryologic studies was connected with the development of the European Northeast in the 1920s–1930s. It has been determined that the USSR Academy of Sciences played the leading role in carrying out these studies: it organized special scientific expeditions for studying the cryolithozone of this region. The main results of the studies and their motives interconnected with the government’s interests in the development of valuable northern mineral resources are shown. The results of the expeditions were conclusions about the possibility of constructing large industrial facilities in the regions of the explored reserves of natural raw material resources. Following scientists’ recommendation, the industrial development of the Pechora coal basin and the colonization of the polar region began. The climatic and natural features of the region demanded stationary scientific research in the field of design and construction. The Vorkuta Research Permafrost Station (VRPS) (1936–1958), created under the supervision of the USSR Academy of Sciences, began to carry out this research. Today, the history of this station’s activities is poorly studied. The article presents the main directions of VRPS research: engineering permafrostology and general issues of permafrost studies. The staff of the station were researchers of the Committee on Permafrost Studies of the USSR Academy of Sciences and scientists from among prisoners of GULAG. The role of the staff who made a great contribution to permafrost studies is shown. Under the leadership of the scientists of the station, on the basis of their techniques, large industrial structures of Vorkuta District and Vorkuta, among them the first railroad in the conditions of permafrost, were designed. The conclusion is drawn on the leading role of scientists of the USSR Academy of Sciences in carrying out studies of permafrost soil in the European Northeast in the first half of the 20th century which became the basis in the successful solution of construction problems in the Arctic territory.

In 1967‑2015, Institute of Geography of the USSR/Russian Academy of Sciences together with other organizations carried out field expeditions in different areas of mountain and polar glaciations in many regions: the Polar Urals, Caucasus, Pamir, Zailiysky and Jungar Alatau, Tien‑Shan, Pamir‑Alai, the Kamchatka Peninsula, the Pyrenees, the Arctic – Spitsbergen, Novaya Zemlya, Franz Josef and Severnaya Zemlya, and Antarctica – on the ice flow B, and in the sub‑Antarctic – Islands King George, Galindez, and Livingston. The gravimetric and ground and aerial radar observations were made in these expeditions. About 300 glaciers of different morphological types and sizes with cold, subpolar and temperate thermal regime were studied. Basic results of these studies are the following: (1) the new data on the ice thicknesses, ice volumes, subglacial relief, internal structure, and thermal state of the glaciers were obtained; (2) the two‑layered (polythermal) glaciers consisting of the upper layer of cold ice and the lower layer of temperate water‑filled ice had been revealed in Svalbard for the first time; spatial distribution of cold, polythermal and temperate glaciers had been determined; (3) the evidences were obtained that measured changes in thickness of the upper cold ice layer in polythermal glaciers can be used to estimate the long‑period variations of regional climates and serve as regional paleothermometers; (4) methods for estimating the water content in temperate and polythermal glaciers from the RES data were developed; and its space‑time variations in temperate ices of the Svaldbald glaciers were estimated since even small water content inside of them can noticeably change their dynamic behavior; (5) methods for estimating the ice volume within glaciers in large regions of mountain and polar glaciations had been created; the ice storages were estimated in Svalbard, Franz Josef Land, Dzhungrsky Alatau, the Great Caucasus, and Mt. Elbrus; (6) detailed data on the ice thicknesses and the subglacial relief had been obtained for 40 glaciers in framework of different national and international programs and projects; the data can be used to solve a wide range of practical and theoretical problems, including numerical modeling. These studies demonstrated the following: (1) the use of monopulse radars VIRL‑6 and VIRL‑7 of decameter range (the central frequency is 20 MHz) with digital recording of the radar and GPS data is quite efficient for ground‑based and airborne (from helicopters) radio‑echo sounding of mountain and polar glaciers with their ice thicknesses up to 500–600 m; (2) it was found that thicknesses of glaciers in the Caucasus and Tien Shan can reach 330–430 m, while in regions of mountain, ice‑sheet and transitional glaciation on the Spitsbergen Archipelago – 300, 560 and 600 m, respectively, on the ice caps of the Franz‑Josef Land and Severnaya Zemlya – 450 and 813 m, and on King George and Livingston Islands (Sub‑Antarctica) – 330 and 500 m; (3) large parts of ice caps and outlet glaciers in Svalbard, Franz Josef Land, Severnaya Zemlya which beds were located below the sea level were found. Precisely these parts can be undergone quick shortening due to climate warming, and, thus, cause formation of icebergs making threats for ships and gas‑oil marine platforms in the Barents and Kara seas; (4) data of the measurements made possible to calculate volumes of a number of investigated glaciers and ice caps and to estimate the ice storages in large areas of mountain and polar glaciations (the Jungar Alatau, Great Caucasus, Spitsbergen, Franz Josef Land); (5) decreasing of glacier volumes on the Franz Josef Land and some Spitsbergen glaciers for the last decades had been estimated. Analysis of the data obtained had shown that considerable part of polythermal glaciers in Spitsbergen belong to type of surging glaciers; they have the winter englacial runoff and form the near‑glacier icings. It allows considering such glaciers as dynamically unstable, predisposed to surges as well as possible sources of winter water supply and additional sources of paleoinformation about long‑period variations of regional climate.

The subject of this research is the historical role of Russian scientific community in studying the Arctic and Subarctic territories during the years of Great Patriotic War. The key goal consists in demonstrating the contribution of scholars to accumulation of scientific knowledge on the northern region in the context of solution of the priority government objective and establishment of scientific organizations on the European North of Russia in first half of the XX century. The main tasks of this research lie in reconstruction of the process of creation and activity of oil shale laboratory of the Base of Academy of Sciences of the Soviet Union on studying the North under the authority of Professor D. N. Kursanov, who dealt with the questions of utilization of solid fossil fuels of the Komi ASSR. This topic did not receive due coverage within the scientific literature. For solution of the set tasks, the author attracted the unpublished archival materials from the Archive of the Russian Academy of Sciences, Scientific Archive of the Federal Research Center “Komi Scientific Center of Ural Branch of the Russian Academy of Sciences” and National Archive of the Komi Republic; writings of the staff members of the indicated laboratory published based on the research results in 1940s, as well modern researchers of the depths of Russian North. The article explores the history of establishment of scientific department, development of scientific programs and plans, organization of interaction of academic community with the government and economic branches of the Komi ASSR. The main conclusions consists in the proof that the scientific-organizational activity of D. N. Kursanov led to conducting strategic research of defense designation on the problems of studying oil shale of the mineral deposit on Ayyva River, utilization of oil shale for motor fuel generation, and elaboration of new chemical products for defense industry. It is underlined that the high level of explorations and pilot surveys carried out by national scholars in these directions contributed to the development of new shale-chemical industrial sector of the country in the later years.

Presents a historical analysis of the research activities of the members of the Expedition No. 1, which was organized by the Obruchev Permafrost Institute of the USSR Academy of Sciences (Moscow) in the Arctic regions of Yakutia in 1952– 1953. This expedition turned out to be the first large-scale geocryological initiative implemented in the named region. In this regard, mainly on the basis of the revealed archival materials, including those introduced by the author for the first time into scientific circulation, a characteristic of the personal composition of the research participants is presented. The geography of the work carried out has been established, covering the previously poorly geocryologically studied Yano- Indigirsky interfluve, the coast of the Laptev Sea and the Bolshoi Lyakhovsky Island, the main routes made by scientists are shown. The key directions of scientific search for permafrost scientists have been identified. The significance of the research carried out for the replenishment of knowledge about the permafrost in the Arctic regions of Yakutia and, in general, the development of geocryological science has been determined. In this regard, plots are presented that characterize the specifics of the geocryological surveys, as well as the improvement of the methodological arsenal of permafrost research in the region. At the same time, it was noted that the work of the members of Expedition No. 1 made it possible to determine a number of the most important features of cryogenic processes and the extent of the spread of permafrost in the Arctic Yakutia, to establish the thickness of the permafrost and its temperature parameters at different depths. In addition, it was found that during the survey a number of important practical results were obtained, including the identification of the composition of permafrost and the depth of the seasonally thawed layer, necessary to optimize the process of transport and industrial development of the region.

The paper presents the results of introduction studies of 20 European species and 2 taxa of the genus Primula L. in N.A. Avrorin Polar-Alpine Botanical Garden-Institute of Kola Scientific Centre of Russian Academy of Sciences. Currently, the collection contains 13 species and 1 taxon ( P . auricula L., P . carpathica Fuss, P . clusiana Tausch, P . daonensis (Leyb.) Leyb., P . elatior (L.) Hill, P . glaucescens Moretti, P . kitaibeliana Schott, P . latifolia Lapeyr, P . minima L., P . poloninensis Fed., P . veris L., P . veris subp. macrocalyx (Bunge) Ldi, P . vulgaris Huds., P . wulfeniana Schott). It has been shown that the species inhabiting the alpine belt of mountains are best adapted to the conditions of the Arctic ( Primula auricula , P . carpathica , P . clusiana , P . halleri , P . minima , P . pedemontana , P . scandinavica , P . vulgaris ssp. rubra , P . tyrolensis , P . wulfeniana - IC (introduction coefficient) = 8,3, as well as P . elatior (IC = 8,1) and P . veris subsp. macrocalyx , P . vulgaris (IС = 7,6). The rest of the studied species are less adapted. It has been established that species of the genus Primula can serve as a source of replenishment of the landscaping assortment for the Murmansk Region. For this purpose 2 new ornamental and resistant species were recommended ( Primula carpathica , P . clusiana ).
