This article examines the key aspects of intellectual property management in the oil and gas industry aimed at ensuring technological sovereignty. The study analyzes the innovation management process using the example of the Arctic Cascade natural gas liquefaction technology and the accumulated experience of innovation implementation using the example of JSC Kronstadt Engineering Center. The study presents a scheme of managerial influence on the formation of an innovative environment in the oil and gas industry, as well as the practical experience of patenting innovative technology.

The  results  of  a  series  of  experiments  conducted  in  June 2023 in the Onega Bay of the White Sea are presented. The study included quasi-temporal in situ and satellite observations in the vicinity of the river plume frontal area formed by the waters of the Onega River. The main objectives were to define the characteristics and dynamics of the area under the influence of tides, as well as to assess the causes of short-term spatial and temporal variability in the characteristics of thermohaline fields. The results show that tides have a significant effect on the structure of waters near the Lyamitsky shore. Here, a large contribution is made by fast-flowing water oscillations associated with short-term internal waves, which frequently occur near the frontal interface. The study demonstrates that the use of high-resolution optical and radar satellite imagery allows a more efficient analysis of frontal and wave dynamics, which is of great importance for understanding the peculiarities of local hydrodynamic processes in the water areas of tidal seas.

In this work, we assess possible negative effects associated with regular maintenance dredging in the port of Sabetta on the marine biological resources and coastal environment of the Gulf of Ob. The costs of environmental protection measures and сountervailing payments are determined. As a restoration activity for fish fauna, it is proposed to implement the artificial reproduction of young fish of valuable species, such as peled, siberian sturgeon, or muksun, followed by their release into the natural environement of the lakes and rivers of the West-Siberian fishery water basin. 

In a previous issue of this journal (Vol. 2, No. 3, 2024), the author characterized the natural conditions of the Varandey coastal tundra area. The present article continues this research, focusing on the ecological state of the components of the natural environment. The data for analysis were obtained through field surveys of the area, analytical studies of the collected specimens, standardized indicators of their quality, as well as from open sources.

The author considers specific features of operation of solid municipal waste landfills at the post-operation stage in northern climate conditions. It is emphasized that safe operation of landfills requires efficient management of landfill gas and leachate formation. Increased precipitation leads to increased waste moisture content and, as a consequence, to methane generation during different seasons. The author presents the results of  measuring methane concentrations and calculating leachate volumes at a  landfill located in the north-west of Russia. The conclusion is made about the need to control and manage leachate formation, as well as to take measures for its treatment to prevent environmental and sanitary-hygienic problems associated with evaporation and accumulation of leachate.

The author sets out to generalize the existing information about a  humanoid creature in the Russian Far North by analyzing the reports of local residents, travelers, and researchers, as well as by studying local legends and folklore tales. The data is evaluated from the perspectives of folklore studies and the theory of testimonial evidence. The reliability of  this evidence, which resonates well with the traces of prehistoric human activity found in Yakutia, cannot be fully ruled out. Given the low anthropogenic load and the scarcity of knowledge about these places, the possibility of the existence of animals, which are unknown to science, cannot be refuted. The  author evaluates the theoretical possibility of the existence of a highly developed primate in northern and other areas of the planet, which cannot be accessed by conventional methods of zoology.

This article presents the results of a  research study into the dynamics of mammal populations in the Nizhnesvirsky Nature Reserve during the 2014–2024 period. The research was conducted using the authors’ field observations and archival data. The influence of a number of factors, i.e., snow cover depth and spruce and pine cone yield, on the mammal populations in the area under study is analyzed. A weak snow cover was shown to be favorable for maintaining high numbers of wild boar populations, while a thicker show cover was more favorable for predators (wolves). The weather conditions favorable for harvest of spruce and pine cones was found to have a positive effect on both herbivores and predators. In the dynamics of relationships between predators and their prey, regular interrelated fluctuations in population numbers are observed.

On September 24, 2024, the Russian State Hydrometeorological University (RSHMU, St. Petersburg, Russia) opened the exhibition entitled “Allied (Northern) Convoys and Lend-Lease 1941–1945”. The exhibition presents unique artefacts provided by the “Northern Convoys International Center” Foundation, including documents, awards, diaries, photographs, sailors’ everyday items, items of lend-lease supplies, family relics of the Northern Convoys veterans. Paintings by Russian and foreign artists dedicated to the Northern Convoys of the Great Patriotic War and World War II are exhibited for the first time.
