In the article was considered species composition of fish in the littoral and sublittoral zones of Yarnyshnaya and Zelenetskaya bays (Barents Sea) during summer 2020. For the first time, the kelp snailfish Liparis tunicatus was recorded in the studied water area. At whole was discovered 15 species of fish and most abundent between them is staghorn sculpin Gymnocanthus tricuspis and shorthorn sculpin Myoxocephalus scorpius. Also quantitative characteristics of the distribution for each fish species are represented. The dynamics of abundance and diversity of coastal fish communities were analyzed. Comparing of perennial data with 2020 indicates that at the present observed relatively rich species composition, low fish distribution density, low abundance of young Gadidae, but high indicators of biodiversity in coastal communities.

This paper presents the results of measurements of δ18O and δ2H stable isotope values in the waters of the Barents Sea, which were carried out in March–April 2021. Based on the data presented, the ratio of base water content – atlantic (fa), river (fr) and melt water (fi), as well as the volume of water withdrawn for ice formation in the studied water area was assessed. The comparative estimation of base water content, calculated on values “δ18O–salinity” and “δ2H–salinity” is presented and obtained values do not exceed limits of mean value ±sd. However, average values of Atlantic and ice water content calculated using δ2H parameter are higher than those using δ18O, and river water content is lower. The use of δ18O and δ2H parameters in oceanographic studies in the calculation of balance characteristics is preferable to temperature and salinity because of their greater conservativity.

The work presents the results of route counts of marine and near-water birds in different parts of the northern coast of the Murmansk region. The seasonal dynamics of the population of the common eider and herring gull in the area of Teriberka were shown, as well as the index of species diversity for some areas of the Kola Inlet. According to the results of observations, changes in the avifauna of some areas of the Pechenga and Kola inlets were noted.

The duration of the pelagic stage in different species of gastropod molluscs affects their ability to disperse by marine currents. We counted the number of species with long (planktotrophic larva) and short or absent (lecitotrophic larva) pelagic stages in development in shell gastropods from 8 areas of the open part of the Barents Sea. A total of 66 species were identified in the study area, of which 25 were true micromolluscs, and 41 species were represented mainly by juvenile individuals of larger molluscsby larger macrofaunal species. The predominant type of development is lecithotrophic (57 species) and partially pelagic planktotrophic (9 species). According to our data, the shares proportions of species with lecithotrophic and planktotrophic types of development are approximately the same in all investigated areas of the Barents Sea. But in the southern part of the Barents Sea the share of species with a long pelagic stage are sligthlyis slightly higher than in more numerous than in its northern part.

The dynamics of polychaete abundance in different climatic phases and their role in biocenoses were analyzed in polychaetes of the Kola Inlet (1995 and 2017). Since 1995, the abundance in the southern and central parts of the bay has not changed, but it increased in the northern part by 2 orders of magnitude. The role of Pholoe in biocenoses increased most strongly in the northern part of the inlet.

The article represents the results of the study of bottom sediment cores taken from the R/V “Dalnie Zelentsy” in the Central Depression of the Barents Sea during the 2022 expedition. The exposed stratum of bottom sediments is composed of silty-pelitic material, in some layers there is an admixture of uneven-grained sand and grains of well-rounded gravel. The chronology of sedimentation was determined by changing the specific activity of excess 210Pb, the obtained data were verified by 137Cs. The rate of sedimentation in the study area over the past 120 years has varied within 0.05–0.1 cm/year.

The paper considers the dependence of changes in the area of ice in the Kara Sea with fluctuations of the Ob and Yenisei rivers runoff during the period from 1978 to 2022. Over the period from 2004 to 2022, statistically significant positive correlations between the summary runoff of the Ob and Yenisei and the area of ice in the Kara Sea were found. There was an acceleration of ice formation processes, an elongation of the ice stabilization period, the beginning of ice melting in a later date and a higher resistance of ice to destruction during summer in the high-water content years of the Ob and Yenisei rivers.

The results of observations of the content of dissolved forms of Fe, Mn, Cr are presented in the surface layer of sea water in the eastern part of the Barents Sea and in the area of the Greenland Sea near the Svalbard archipelago. The observations were made during the complex expeditions of the MMBI RAS in 2021 and 2022. The concentration of these microelements was measured by atomic absorption spectroscopy using a “KVANT.Z” spectrometer. Maps of the distribution of these elements of the study areas are presented, the average concentration of heavy metals did not exceed the maximum allowable concentrations for marine fishery water bodies in the waters of the studied areas. In general, the content of HMs in the waters of the Isfjord and its branches is lower than in the waters of the Barents Sea. The maximum range of heavy metals content variability is also observed in the Barents Sea. The largest spatial variation characterizes in concentrations the distribution of dissolved forms of Fe in the studied basins.

The aim of the work is to analyze interesting archaeological sites of the North — pit traps known in the tundra and north taiga zones of Fennoscandia. The article deals with the main issues of their study in Northern Finland and Lapland. By the beginning of the XXI century, Finnish archaeologists had done a lot of work in studying the hunting pits. Systems of hunting pits were built together with the long special fencep. The main objects of hunting are reindeer and elk. Pit traps were used from the Mesolithic to the XVI century. In the Middle Ages in Fennoscandia, traps could be made by aborigines — Sami and neighboring peoples — Karelians, Finns. In a comprehensive study of ethnography and archeology, hunting pits are good informative archaeological object.

The article is devoted to the history of the mono-ethnic German family. The article is based on the materials of the family archive, which was created thanks to the commemorative practices of the representatives of the family. Interesting facts and discrepancies in archival documents were revealed. The history of the family is known from the 18th century, when their ancestors moved from Swabia to Russia in 1765 under the influence of the Manifestos of Catherine II. In the 1930s–1940s members of the family experienced tragic events that many German families had to go through. This period is represented by the largest number of materials. The main purpose of creating an archive is to perpetuate the memory of the history of the family for posterity.
