At present, a relevant task consists in understanding the seismicity of the European Arctic sector in general and the Barents-Kara region in particular. Due to the small number of seismic stations installed in the Arctic region our understanding of the seismicity of the Arctic is still not properly investigated. However, as a consequence of the operationalisation of the seismic station SVZ Severnaya Zemlya on the Severnaya Zemlya archipelago since 2016, it has become possible to record and process an increased number of seismic events. Data from the Arkhangelsk seismic network were compared with a map of the spatial distribution of earthquake epicentres in the Barents-Kara region and adjacent waters for 2017–2018 created by various seismological agencies. The distribution of the number of earthquakes by magnitude and location registered by the Arkhangelsk seismic network for 2012–2018 are presented. The greatest number of earthquakes is associated with the Gakkel, Knipovich and Mohn Ridges, while the lowest number is associated with the St. Anne trough We compared the number of earthquakes recorded by the Arkhangelsk seismic network in 2017–2018 with those recorded by the Severnaya Zemlya station in the same period. The increased number of recorded earthquakes indicates the importance of opening the Severnaya Zemlya station in Arctic region. The microseismic background level was considered and charts drawn up comparing the daily power spectra of SVZ for the “best” and the “worst” months in terms of seismogram quality. Using an earthquake recorded in the eastern part of the Gakkel ridge as an example, the effective processing of the earthquake record in the WSG software package including the operation of the new SVZ station is demonstrated.

AbstractNorthern countries are facing the challenges of declining human capital, and admitting immigrants, many of whom belong to religious minorities, to satisfy the demand for labour. If northern societies accept multiculturalism and immigrants, they should not disregard the cultures and religious practices (for example, ritual slaughter) of immigrants, as they need to survive and integrate as a minority community in a secular society. However, there is clash between secularism and religions permitting animal slaughter, which is prohibited by some and allowed by other European countries. Community viability and sustainability depend partly on the exercise of community beliefs and ideology that support identity behaviour. This study will present an ethnographic analysis of the religiosity related to ritual slaughter and Muslim cultural identity in the European Arctic region and explore how religious relativism and practice sustain the community and support the overall integration of the Muslim minority in the North.

The article provides an overview and analysis of seismicity within the boundaries of the Arctic region for 2015, a description of seismic station networks, and processing methods. The catalog of earthquakes in the Arctic region was compiled on the basis of catalogs of several organizations and seismological centers. In total, 334 earthquakes are included in the earthquake catalog. Most of the earthquakes that occurred in 2015, including all the strongest earthquakes, were located within the mid-ocean ridges of Mon, Knipovich and Gakkel. In the offshore territories, most of the earthquakes were confined to the Svalbard archipelago, in particular, to the seismically active zone in the Sturfjord strait. The renewal of instrumental seismological observations in 2011 (station ZFI) on Alexandra Land Island in the Franz Josef Land archipelago made it possible to record weak earthquakes in the north of the shelf of the Barents and Kara Seas. For twelve earthquakes, the focal mechanism parameters are presented according to the Global CMT catalog.

Abstract. In spring 2006 a special meteorological situation occurred in the European Arctic region giving record high levels of air pollution. The synoptic situation resulted in extensive transport of pollution predominantly from agricultural fires in Eastern Europe into the Arctic region and record high air-pollution levels were measured at the Zeppelin observatory at Ny-Ålesund (78°54' N, 11°53' E) in the period from 25 April to 12 May. In the present study we investigate the optical properties of the aerosols from this extreme event and we estimate the radiative forcing of this episode. We examine the aerosol optical properties from the source region and into the European Arctic and explore the evolution of the episode and the changes in the optical properties. A number of sites in Eastern Europe, Northern Scandinavia and Svalbard are included in the study. In addition to AOD measurements, we explored lidar measurements from Minsk, ALOMAR (Arctic Lidar Observatory for Middle Atmosphere Research at Andenes) and Ny-Ålesund. For the AERONET sites included (Minsk, Toravere, Hornsund) we have further studied the evolution of the aerosol size. Importantly, at Svalbard it is consistency between the AERONET measurements and calculations of single scattering albedo based on aerosol chemical composition. We have found strong agreement between the satellite daily MODIS AOD and the ground-based AOD observations. This agreement is crucial for the radiative forcing calculations. We calculate a strong negative radiative forcing for the most polluted days employing the analysed ground based data, MODIS AOD and a multi-stream model for radiative transfer of solar radiation.

Abstract. In spring 2006 a special meteorological situation occurred in the European Arctic region giving record high levels of air pollution. The synoptic situation resulted in extensive transport of pollution predominantly from agricultural fires in Eastern Europe into the Arctic region and record high air-pollution levels were measured at the Zeppelin observatory at Ny-Ålesund (78°54' N, 11°53' E) in the period from 25 April to 12 May. In the present study we investigate the optical properties of the aerosols from this extreme event and we estimate the radiative forcing of this episode. We examine the aerosol optical properties from the source region and into the European Arctic and explore the evolution of the episode and the changes in the optical properties. A number of sites in Eastern Europe, Northern Scandinavia and Svalbard are included in the study. The observations show that the maximum AOD was from 2–3 May at all sites and varies from 0.52 to 0.87, and the corresponding Ångstrøm exponent was relatively large. Lidar measurements from Minsk, ALOMAR (Arctic Lidar Observatory for Middle Atmosphere Research at Andenes) and Ny-Ålesund show that the aerosol layer was below 3 km at all sites the height is decreasing from the source region and into the Arctic. For the AERONET sites included (Minsk, Toravere, Hornsund) we have further studied the evolution of the aerosol size. The single scattering albedo at Svalbard is provided for two sites; Ny-Ålesund and Hornsund. Importantly the calculated single scattering albedo based on the aerosol chemical composition and size distribution from Ny-Ålesund and the AERONET measurements at Hornsund are consistent. We have found strong agreement between the satellite daily MODIS AOD and the ground-based AOD observations. This agreement is crucial for accurate radiative forcing calculations. We calculate a strong negative radiative forcing for the most polluted days employing the analysed ground based data, MODIS AOD and a multi-stream model for radiative transfer of solar radiation. During this specific pollution event the forcing reached values as low as −35 W m−2 in the region. For comparison, the direct forcing of a corresponding aerosol layer with a typical AOD of 0.05 for the season is around −5 W m−2.

The Federal Research Center for the Integrated Study of the Arctic named after N. P. Laverov, conducts monitoring of the Western Sector of the Russian Arctic on the basis of the Arkhangelsk Seismic Network (ASN). We presented data on the number of earthquakes registered by ASN stations for 2016—2020, diagrams of the distribution of the number of events by magnitude, and also a map of the spatial distribution of earthquake epicenters. We examined operating results of the Kolba seismic station opened in 2020 as a part of ASN in the Dixon Village of the Taimyr Dolgan-Nenets district of the Krasnoyarsk region of Russia. The obtained results demonstrated the contribution of the Arkhangelsk seismic network to the formation of modern ideas about the Arctic seismicity.

An overview of regional seismicity registered by the Arkhangelsk seismic network is presented. In 2013 the Arkhangelsk seismic network included 9 digital seismic stations (ARH, KRR, PRG, TMC, PRO, LASH, SLV, AMD, and ZFI/ZFI2). A large number of technogenic events were recorded by the Arkhangelsk network in the north of the East European Platform (Arkhangelsk Region). Only 2 earthquakes were registered during the entire observation period: on October 22, 2005, at 17h46m with ML=2.9, and on March 28, 2013, at 07h02m with ML=3.4. The parameters of the hypocenter of the March 28, 2013 earthquake were evaluated using all currently available source data and bulletins of Russian and foreign seismic stations. The evaluation was done using the method of Generalized beamforming, in an improved form, implemented in the program NAS (New Association System). This earthquake is reprocessed using the same initial data (26 arrivals of seismic P- and S-phases from 13 seismic stations) by the NAS program. The epicentral distances ranged from 85 to 1800 km. The final parameters of the epicenter are as follows: 28.03.2013, t0=07:02:16.2, φ=63.95°N, λ=41.57°E. The epicenter is located 80 km south of Arkhangelsk in a sparsely populated area slightly west of the Severnaya Dvina River. The probable source depths lie in the interval from 2 to 33 km and the depth with the maximal value of the rating function is 19 km. A map of earthquakes in the Arctic region is provided. Earthquakes were registered by stations of the Arkhangelsk seismic network and processed together with the waveforms from other networks. The distribution of earthquakes correlates with the seismic zones of the Arctic – the Knipovich and Gakkel ridges, Spitsbergen. There are weak earthquakes on the shelf of the Barents Sea near the Frantz Josef land archipelago, as in 2012. They relate to the trench of Franz Victoria, the border of the continental slope, and the island of Bely. The coordinates of the epicenters of 290 earthquakes were determined in 2013. The representative level of the Euro-Arctic region's magnitude for 2013 according to the Arkhangelsk network was 2.9.

In the conditions of further development of the Arctic it is especially important to preserve the health of the population permanently or temporarily located in this territory. In recent years significant changes have taken place in the biosphere of the Arctic region under the influence of natural and anthropogenic factors. The population morbidity is accounted for by a number of diseases. However, the infectious component and the factors contributing to its growth remain poorly understood. Objective. To study various biocenoses in the Arctic region as potential risk areas for the spread of infectious diseases among the population. Materials and methods. The material for microbiological studies was selected in 2018–2019 in the archipelagos of Svalbard and Severnaya Zemlya. A total of 139 samples from various samples of natural, anthropogenic and ornithogenic biocenoses were studied. Research methods: classical bacteriological, MALDI-TOF mass spectrometric analysis, statistical data analysis. Results. During the study of Arctic samples were isolated and identified 309 viable bacterial strains and representatives of 117 species of micromycetes. Of all the isolated strains, the most important are Escherichia coli, Yersinia intermedia, representatives of the genera Acinetobacter, Pseudomonas, Stenotrophomonas, Serratia, Enterobacter, Enterococcus, and Staphylococcus. Conclusion. The risk factors for the spread of infectious disease pathogens in the Arctic region were identified: an increase in the number and diversity of isolated microorganisms of medical significance in dynamics; identification of pathogens of infections associated with medical care and saprozoonoses among them. Key words: Arctic, Svalbard and Severnaya Zemlya archipelagos, infectious diseases, pathogens of medical care-related infections and saprozoonoses, polar microorganisms

The review of the Arctic basin seismicity for 2013 is presented. It is based mainly on the data from the sta-tions of world network, located outside the basin. The data from a single local seismic station was used. It was "Franz Josef Land" station with two sets of seismic sensors, ZF1 and ZF2. The station is a part the Ar-khangelsk network, operating in the region since September 2011. There were 38 earthquakes with mb=3.0–4.6 in the Arctic basin in total. A map of their epicenters is provided. 28 of them are connected with the seismically active zone, which extends through the deep-water part of the Arctic basin to the shelf of the Laptev Sea. For two earthquakes, the parameters of focal mechanisms are given according to the GCMT da-ta. The magnitude frequency distribution for 2013 is compared with the distributions for 1990-2012. The level of seismic energy released in 2013 is 1.3 times lower than in 2012 and 1.6 times higher than its average one for 23 previous years. The distribution of earthquakes in the Arctic region in 2013 is presented.
