Abstract: The purpose of the article is to determine the main ways of organization of the activity of the USSR Academy of Sciences in Yakutia during 1947-1991. The initial chronological boundary is connected with the creation of the Yakut branch of the USSR Academy of Sciences. The final boundary is due to the reorganization of the USSR Academy of Sciences in
The Russian Academy of Sciences, accompanied by profound changes in the management and functioning of domestic science. The research is based on the analysis of scattered documentary evidence identified in the archival collections of Moscow, Novosibirsk and Yakutsk, as well as data from the scientific literature relevant to the issue under consideration. In this regard, the history of the formation of a network of institutions subordinate to the USSR Academy of Sciences in Yakutia is considered, the main mechanisms of the organization of academic institutions and the key drivers of this process are traced. When processing the accumulated materials, special historical methods of scientific cognition were used (the principle of historicism, historical-typological, historical-comparative and historical-genetic methods, etc.) As a result of the work carried out, for the first time in historiography, it was established that the organization of institutes of the USSR Academy of Sciences in Yakutia during the period under review took place in three ways: transition to the Academy a research institute that already existed in Yakutia; the creation of institutes based on existing departments, as well as outside it; the formation of a functioning academic institute on the basis of the department. At the same time, the expansion of the network of institutes, in addition to the natural, geographical and ethnocultural specifics of Yakutia, was caused by a significant deepening of the specialization of scientists' research and was based on an increase in the number of employees, as well as the number of internal structural units. Such a development, as shown, was impossible without changes in the ways of recruiting personnel and strengthening the role of specialists trained directly in the region, who by the end of the period under review managed to take a leading position in the management of academic science in Yakutia.

Abstract: The aim of the work is to create a dynamic picture of the development of the forms of research of the USSR Academy of Sciences in Yakutia in 1947-1991. The initial chronological boundary is connected with the organization of the Yakut base of the USSR Academy of Sciences. The final boundary is due to the reformatting of the USSR Academy of Sciences into the Russian Academy of Sciences. The research is based on the involvement of documents from the archives of the Yakut Scientific Center of the Siberian Branch of the Russian Academy of Sciences, the Archive of the P.I. Melnikov Permafrost Institute of the Siberian Branch of the Russian Academy of Sciences, the Current Archive of the Yu.G. Shafer Institute of Cosmophysical Research and Aeronomy of the Siberian Branch of the Russian Academy of Sciences (Yakutsk), the Scientific Archive of the Siberian Branch of the Russian Academy of Sciences (Novosibirsk), the Archive of the Russian Academy of Sciences (Moscow), as well as information presented in the available scientific literature. When processing the accumulated materials, special historical methods of scientific cognition were used (the principle of historicism, historical-typological, historical-comparative and historical-genetic methods, etc.). For the first time in historiography, a characteristic of the development of forms of organization of academic research in Yakutia in the period 1947–1991 is presented. It is noted that during the period considered in the article, the forms of organization of academic research in Yakutia have received significant development. The expedition surveys of the staff of the USSR Academy of Sciences were continued, which were carried out with greater intensity than before. An important place was occupied by stationary research, which unfolded on a network of hospitals in various parts of Yakutia. In addition, experimental and design work carried out in academic institutions established in the region was characterized by a number of achievements. This state of affairs has allowed the academic center to conduct a complex of largely unique research focused not only on obtaining fundamental, but also applied, of serious practical importance, results.

Abstract: The historical analysis of the research carried out during 1928-1934 within the framework of the Kola peninsula expedition of the USSR Academy of Sciences is presented. The initial boundary is due to the creation of the expedition, the final one is due to its reformatting into a stationary structure – the Kola base of the USSR Academy of Sciences. The sources for the preparation of the article are archival materials identified by the authors from the Archives of the Russian Academy of Sciences, published expedition reports, as well as scientific literature prepared based on the results of the research under consideration. It is noted that the drivers of the Kola complex expedition were both purely cognitive interest and the needs of industrial development of high latitudes. The work carried out made it possible to show significant activity of researchers in studying the natural resources of the Kola Peninsula, identifying promising mineral deposits, determining various patterns of their distribution and searching for the optimal development methodology. Along with this, a certain place in the work of the expedition was given to other areas of research, both related to ensuring the possibility of developing the extractive industry (geocryological, partly ecological and biological), and having an indirect connection with this problem. In this regard, the importance of conducting research within the expedition aimed, among other things, at studying the traditional culture of the aboriginal ethnic groups of the Kola Peninsula is noted.

Abstract: The purpose of the article is a historical and anthropological reconstruction of the traditional economic practices of the Yakuts, in which the most important place was occupied by the exploitation of cryogenic resources (cold, snow, ice, "permafrost"). The work is based mainly on the analysis of observations by researchers of the second half of the XIX – first half of the XX centuries, who recorded in the course of their expedition surveys a number of stories concerning the practices of the use of cryogenic resources by the Yakuts in economic activities. Methodologically, the article is based on the principles of cryosophy, involving the study of the cold matter of the Earth through the prism of their role as an active element of the universe, a source of benefits and opportunities for humanity, as well as a historical and anthropological approach. The article for the first time shows a number of examples of successful and active exploitation of cold, snow, ice and "permafrost" in the traditional economic activities of the Yakuts within the framework of such a plan: cattle breeding and horse breeding, fishing and hunting, as well as in the organization of salt production. Based on accumulated materials, including documents from the Archives of the Russian Academy of Sciences and its St. Petersburg branch, the State Archive of the Irkutsk Region, the Scientific Archive of the Siberian Branch of the Russian Academy of Sciences, the Scientific Archive of the Russian Geographical Society and the Manuscript Fund of the Archive of the Yakut Scientific Center SB RAS, the authors conclude that cryogenic resources were one of the important adaptation mechanisms Yakuts to the natural and geographical realities of Yakutia.

Abstract: The historical analysis of the studies carried out during the 1950s-1980s by the staff of the Yakutsk Permafrost Research Station of the Obruchev Permafrost Institute of the USSR Academy of Sciences and since 1962 – organized on its basis by the Permafrost Institute of the Siberian Branch of the USSR Academy of Sciences and aimed at studying the coastal-shelf zone of the Laptev Sea and the East Siberian Sea. The sources for the preparation of the article were the archival materials identified by the author from the funds of the Russian State Archive of Economics and the Archive of the Melnikov Permafrost Institute of SB RAS, as well as scientific literature data. The work carried out made it possible to show the significant activity of researchers in the study of subbottom permafrost. Its drivers were both purely cognitive interest and the needs of the industrial development of high latitudes. In the course of the surveys carried out, data were obtained characterizing the prevalence and thickness of subpermafrost, its temperature regime, composition and other properties.
