<p>The species <em>Scolelepis finmarchicus</em> sp. nov. is described from the Norwegian and Barents Seas along the northern Norwegian coast and Kola peninsula. The occurrence of this species in the Kola Bay could be seen as a sign of climate warming in the area. Taxonomic issues existing in the genus <em>Scolelepis</em> within the area along the Norwegian coast and in the Barents Sea are briefly touched upon. Seven species belonging to <em>Scolelepis</em> have recently been recorded from the Atlantic sector of the Arctic. <em>Scolelepis</em> (<em>S</em>.) <em>matsugae</em> Sikorski, 1994 is newly synonymized with <em>S</em>. (<em>S</em>.) <em>laonicola</em> (Tzetlin, 1985). This article provides a brief review of <em>Scolelepis</em> together with an identification key for the genus from the Atlantic sector of the Arctic</p>

We present two new quantitative July mean temperature (Tjul) reconstructions from the Arctic tree-line region in the Kola Peninsula in north-western Russia. The reconstructions are based on fossil pollen records and cover the Younger Dryas stadial and the Holocene. The inferred temperatures are less reliable during the Younger Dryas because of the poorer fit between the fossil pollen samples and the modern samples in the calibration set than during the Holocene. The results suggest that the Younger Dryas Tjulin the region was 8.0–10.0°C, being 2.0–3.0°C lower than at present. The Holocene summer temperature maximum dates to 7500–6500 cal yr BP, with Tjulabout 1.5°C higher than at present. These new records contribute to our understanding of summer temperature changes along the northern-European tree-line region. The Holocene trends are consistent in most of the independent records from the Fennoscandian–Kola tree-line region, with the beginning of the Holocene thermal maximum no sooner than at about 8000 cal yr BP. In the few existing temperature-related records farther east in the Russian Arctic tree line, the period of highest summer temperature begins already at about 10,000 cal yr BP. This difference may reflect the strong influence of the Atlantic coastal current on the atmospheric circulation pattern and the thermal behaviour of the tree-line region on the Atlantic seaboard, and the more direct influence of the summer solar insolation on summer temperature in the region east of the Kola Peninsula.

Iron ore in significant quantities has been found in only four areas in arctic Europe. No deposits are known in arctic Asia or in the arctic islands of the eastern hemisphere. The largest iron-bearing area is in Swedish Lapland of which the total known reserves, mainly magnetite and hematite, are estimated at 2413 million metric tons, with an average iron content of over 63 per cent, or a ferric weight of about 1532 million tons. The greater part of this ore requires no concentration before use. There is a deposit of about 1000 million tons in Sør-Varanger in north Norway, with a low iron content, while the deposit at Yena in Kol'skiy Poluostrov (Kola peninsula) is estimated at nearly 850 million tons of ore with an iron content of 23 to 48 per cent, and like the Varanger ore requires concentration. A deposit with an iron content of 30 to 40 per cent has been investigated recently at Kolari in north-west Finland, but it is not yet worked.

ABSTRACTSome Arctic scholars believe that modern reindeer herding on the Kola Peninsula has cultural continuity with the traditional period of such activity in the late 19th century. Others believe that by World War II, Soviet repression of Saami leaders, collectivisation of herding villages, and relocation of families had eliminated many traditional behaviours, especially in the Lake Imandra watershed. This study utilises informant interviews with survivors of the Babinski and Ekostrovski Saami reindeer herding villages and archival materials to understand how their families used land and water to fish, hunt, and obtain other resources including cash labour. As part of the United States National Science Foundation's human dimensions of the Arctic system (HARC) programme to examine how humans are both shaped by, and shape, the Arctic environment, the authors document how lands and waters formed traditional resource territories for Saami herding families. The results reveal that prior to their destruction, western Kola reindeer herding villages were integrated along family lines, with villages sharing mates, resource territories, and economic activities. This paper argues that there was, in fact, no cultural continuity between traditional Saami reindeer herding villages and modern herding structures such as the post-Soviet brigade on the western Kola Peninsula.

Abstract. The smelter industry in Kola Peninsula is the largest source of anthropogenic SO2 in the Arctic part of Europe and one of the largest within the Arctic domain. Due to socio-economic changes in Russia, the emissions have been decreasing especially since the late 1990s resulting in decreased SO2 concentrations close to Kola in eastern Lapland, Finland. At the same time, the frequency of new particle formation days has been decreasing distinctively at SMEAR I station in eastern Lapland, especially during spring and autumn. We show that sulfur species, namely sulfur dioxide and sulfuric acid, have an important role in both new particle formation and subsequent growth and that the decrease in new particle formation days is a result of the reduction of sulfur emissions originating from Kola Peninsula. In addition to sulfur species, there are many other quantities, such as formation rate of aerosol particles, condensation sink and nucleation mode particle number concentration, which are related to the number of observed new particle formation (NPF) days and need to be addressed when linking sulfur emissions and NPF. We show that while most of these quantities exhibit statistically significant trends, the reduction in Kola sulfur emissions is the most obvious reason for the rapid decline in NPF days. Sulfuric acid explains approximately 20–50% of the aerosol condensational growth observed at SMEAR I, and there is a large seasonal variation with highest values obtained during spring and autumn. We found that (i) particles form earlier after sunrise during late winter and early spring due to high concentrations of SO2 and H2SO4; (ii) several events occurred during the absence of light, and they were connected to higher than average concentrations of SO2; and (iii) high SO2 concentrations could advance the onset of nucleation by several hours. Moreover, air masses coming over Kola Peninsula seemed to favour new particle formation.

This study evaluates the development of Crataegus maximowiczii when introduced to the Kola Peninsula. The paper presents the timing of the onset of phenological phases, morphometric indicators of inflorescences and flowers, fruits, features of seed reproduction. C. maximowiczii is a plant with an early onset and short growing season. C. maximowiczii has a short shoot growth period, a short prefloral period, annual flowering and fruiting. The studied specimens of C. maximowiczii plants were characterized by heterogeneous morphometric parameters of flowers and inflorescences. Specimens with a denser inflorescence are characterized by a greater number of flowers per inflorescence, specimens with small flower sizes form medium-sized inflorescences. The species specificity factor affects the morphometric characteristics of inflorescences. Fruiting indicators largely depended on external conditions, among which temperature and relative humidity of the air have little effect. Plants of C. maximowiczii, when introduced to the Kola Peninsula, can be classified as small-fruited. The highest germination capacity is possessed by the samples with average values of mass, which have undergone combined pre-sowing preparation. The relative humidity of the air during the growing season has a greater effect than the temperature regime on the values of the mass of seeds for a given species under conditions of introduction.

Abstract. The metallurgical industry in the Kola Peninsula, north-west Russia, form, after Norilsk, Siberia, the second largest source of air pollution in the Arctic and subarctic domain. Sulfur dioxide (SO2) emissions from the ore smelters are transported to wide areas, including Finnish Lapland. We performed investigations on concentrations of SO2, aerosol precursor vapours, aerosol and ion cluster size distributions together with chemical composition measurements of freshly formed clusters at the SMEAR I station in Finnish Lapland relatively close (∼ 300 km) to the Kola Peninsula industrial sites during the winter 2019–2020. We show that highly concentrated SO2 from smelter emissions is converted to sulfuric acid (H2SO4) in sufficient concentrations to drive new particle formation hundreds of kilometres downwind from the emission sources, even at very low solar radiation intensities. Observed new particle formation is primarily initiated by H2SO4–ammonia (negative-)ion-induced nucleation. Particle growth to cloud condensation nuclei (CCN) sizes was concluded to result from sulfuric acid condensation. However, air mass advection had a large role in modifying aerosol size distributions, and other growth mechanisms and condensation of other compounds cannot be fully excluded. Our results demonstrate the dominance of SO2 emissions in controlling wintertime aerosol and CCN concentrations in the subarctic region with a heavily polluting industry.

Using the example of four large regions of the Arctic zone of Russia, the authors show the wide development of potentially metalliferous conglomerates of various ages, composition, stratigraphic and structural positions. Information on the metal content of the Precambrian conglomerates of the Kola Peninsula and the Anabar Shield is extremely limited. The metal content of the Precambrian conglomerates is well studied only in the Vetreny Belt in the Arkhangelsk Region. The revealed geochemical features reflect the lithological and mineral composition of the conglomerates. Small and medium-scale industrial placers of gold and platinum, other strategic minerals and their placers mark the areas of the Paleozoic and Mesozoic conglomerates within the Taimyr-Severozemelskaya Province and in the Pekulney-Zolotogorsky district of Eastern Chukotka. The authors indicate the prospects for the development of the mineral resource base of placer deposits.
