Перевод заглавия: The magnetic effects of the Tunguska events in 1908
Кл.слова (ненормированные):
термонамагниченность -- Thermomagnetization -- Tungus cosmic body -- microparticles and submicronic inclusions of iron and its oxides -- paleomagnetic properties of soil -- Тунгусское космическое тело -- микрочастицы и субмикронные вкрапления железа и его окислов -- палеомагнитные свойства почвы
Аннотация: Предлагается новое объяснение геомагнитного эффекта, зарегистрированного магнитографами Иркутской обсерватории во время тунгусской катастрофы 1908 года. Эффект состоял в локальном возмущении геомагнитного поля, начавшемся через две с половиной минуты после основного взрыва в эпицентре тунгусских событий в бассейне реки Подкаменная Тунгуска Красноярского края. Возмущение продолжалось 6 часов и носило немонотонный характер. К настоящему времени выдвинуто несколько гипотез для объяснения этого эффекта. Но большая часть этих гипотез не согласуется с другими данными, а остальные пока не подтверждены количественными показателями или модельными расчетами. Излагаемое здесь объяснение основано на установленном факте распыления в атмосфере микрочастиц и субмикронных вкраплений железа и его окислов в результате абляции и взрыва как главной части тунгусского космического тела, так и его других фрагментов. При остывании этих микрочастиц и вкраплений ниже определенной температуры (называемой точкой Кюри) в магнитном поле Земли за счет хорошо изученного эффекта термонамагничивания они получили значительный удельный магнитный момент. После этого они двигались с учетом взаимодействия с магнитным полем Земли, преимущественно вдоль магнитных силовых линий. В результате осаждения они образовали зоны повышенной намагниченности и повышенной магнитной восприимчивости почв в районе тунгусской катастрофы. Эти зоны тщательно выделены А. П. Бояркиной и С. Д. Сидорас в ходе палеомагнитных исследований рыхлых осадочных пород района тунгусской катастрофы. Причем они существенно отличаются от зон повышенного выпадения других немагнитных материалов. Более того, геометрический анализ зон выпадения магнитных материалов позволяет оценить наклон траектории главного космического тела. Эта оценка в сочетании с другими данными дает довольно большой угол входа тунгусского космического тела к поверхности Земли - около 76. Такая величина угла находится в согласии с результатами современного математического моделирования высоты взрыва главного тунгусского космического тела.
In the paper a new explanation for the magnetic effect registered by magnetographs of the Irkutsk Observatory during the Tunguska catastrophe in 1908 is presented. The effect was due to a local perturbation of the geomagnetic field, which began two and a half minutes after the main explosion at the epicenter of the Tunguska event in the basin of the Podkamennaya Tunguska River in Krasnoyarsk Region. The disturbance lasted for 6 hours and had a non-monotonic behavior. By now, several hypotheses have been proposed to explain this effect. But the most part of them is not consistent with other data, and the others have been not yet confirmed by quantitative parameters or model computations. The present explanation is based on the established fact of the sputtering of microparticles and submicron inclusions of iron and its oxides in the atmosphere as a result of the ablation and the explosion of the main part of the Tunguska cosmic body and its other fragments. These microparticles and inclusions, when cooling below a certain temperature (called the Curie point) in the Earth's magnetic field due to the well-studied effect of termomagnetization, received a significant unit magnetic moment. After that they moved with regard to the interaction with the Earth’s magnetic field, mainly along the magnetic field lines. In consequence of the deposition, they formed zones of high magnetization and high magnetic susceptibility of soils in the Tunguska catastrophe area. These zones were carefully marked out by A. P. Boyarkina and S. D. Sidoras during the paleomagnetic studies of friable sediments in the Tunguska catastrophe area. Moreover, they differ significantly from the areas of increased deposition of other, non-magnetic materials. Furthermore, the geometrical analysis of deposition areas of magnetic materials admits estimating the trajectory slope of the main cosmic body. This estimation in combination with other data gives a quite large entrance angle of the Tunguska cosmic body to the surface of the Earth about 76 This angle magnitude is in agreement with the results of the modern mathematical modeling of the explosion height of the main part of the Tunguska cosmic body.

Перевод заглавия: Structural organization of bottom fauna in the Yenisey basin (upstream and midstream)
Кл.слова (ненормированные):
водотоки -- rivers -- Krasnoyarsk region -- the Yenisey basin -- zoobenthos -- taxonomic composition -- abundance -- biomass -- spatial dynamics -- красноярский край -- бассейн р. Енисей -- зообентос -- таксономический состав -- численность -- биомасса -- пространственная динамика
Аннотация: Исследованы сообщества зообентоса в р. Енисей (от истока до устья р. Ангары) и его притоках (рр. Абакан, Мана, Кан, Агул, Кунгус). Все водотоки являются горными реками, в донной фауне которых преобладают литореофильные организмы, заселяющие каменистые грунты на большом течении. В зообентосе обнаружен 231 вид макробеспозвоночных, широко распространенных в Палеарктике и Голарктике. Доминирующие комплексы характеризовались изменчивостью по мере удаления от истоков рек. В р. Енисей видовой состав бентонтов расширялся от верховья к низовью. В верховье Енисея (республика Тыва) ядро донных сообществ представляли поденки, ручейники и хирономиды. На территории Республики Хакасия определяющим фактором для формирования структуры зообентоса являлось обилие фитоценозов, где абсолютными доминантами являлись байкальские амфиподы Gmelinoides fasciatus. В зообентосе Среднего Енисея (от плотины Красноярской ГЭС до устья р. Ангара) по сравнению с верховьем существенно возросла доля хирономид. В притоках видовой состав бентонтов разнообразнее, чем в Енисее; максимальным видовым богатством отличались рр. Мана и Кан. Донные сообщества в притоках Енисея представлены преимущественно хирономидами и поденками, в р. Кан численность дополняли ручейники. Трофический статус Верхнего Енисея, а также притоков Абакан и Агул соответствовал умеренному классу (α-мезо-трофный); р. Кунгус относится к среднему классу (β-мезотрофный); Средний Енисей вместе с притоками Мана и Кан характеризуется повышенной трофностью (α-евтрофный). Выявлена смена структурообразующих комплексов зообентоса в рр. Мана, Агул, Кунгус по сравнению с более ранними исследованиями.
The zoobenthos communities in the river Yenisey (from the head to the mouth of the Angara River) and in its tributaries (rivers Abakan, Mana, Kan, Agul, Kungus) were investigated. All the watercourses are mountain rivers, in the bottom fauna of which lithoreophilic organisms, that inhabit stony soils on a large current, predominant. 231 species of macroinvertebrates, widely distributed in the Palearctic and the Holarctic, were found in the zoobenthos. Dominant complexes were characterized by variability as they moved away from the heads of the rivers. In the river Yenisey zoobenthos species composition expanded from the upper to the lower reaches. In the upper reaches of the Yenisey (Republic of Tuva), the core of the bottom communities was represented by mayflies, caddis flies and chironomids. In the territory of the Republic of Khakassia, the determining factor for the formation of the zoobenthos structure was the abundance of phytocenoses, where the Baikalian amphipods Gmelinoides fasciatus were absolute dominants. In the zoobenthos of the Middle Yenisey (from the dam of the Krasnoyarsk hydroelectric station to the mouth of the Angara River), the proportion of chironomids increased substantially in comparison with the upper reach. In tributaries the zoobenthos species composition is more diverse than in the Yenisey; the maximum species wealth was in the rivers Mana and Kan. Benthic communities in the tributaries of the Yenisey are represented mainly by chironomids and mayflies, Kan was supplemented by caddis flies. Trophic status of the river Yenisey in the upper reaches and of the tributaries Abakan and Agul was «Moderate» class (α-meso-trophic); the river Kungus belongs to the «Middle» class (β-mesotrophic); the Middle Yenisey together with the tributaries Mana and Kan is characterized by «Increased» trophicity (α-eutrophic). A change in the structure-forming complexes of the zoobenthos in the rivers Mana, Agul, Kungus was revealed, comparing to earlier studies.

Аннотация: Computational technology for multiprocessor computing systems of cluster architecture is developed, the ultimate goal of which is numerical modeling of wave fields generated by the electromagnetic pulse source "Yenisei" in blocky-layered geomedia. To describe the wave processes, mathematical models of the dynamics of elastic and elastic-plastic media, of porous and granular materials are applied. The algorithms of numerical realization are constructed based on the method of two-cyclic splitting with respect to spatial variables. Computational experiments showed that the proposed technology allows reproducing the system of waves near the region of excitation of seismic oscillations in 3D setting with a high degree of details and accuracy. The results of computations can be used in working out the optimal modes of functioning the source "Yenisei", when mechanical characteristics of the layers vary in a wide range from solid and frozen grounds with inclusions of rock till granular and clayey water-saturated grounds. Numerical analysis makes also possible to obtain the averaged data, necessary for the adequate simulation of the localized pulse action from the source, using simplified mathematical models for calculating the synthetic seismograms of reflected waves over large scale and at great depth of layers bedding in complex geomedia. © Published under licence by IOP Publishing Ltd.

We developed a mathematical model based on the equations of thermal conductivity for frozen and thawed layers. Those areas in which are lakes or bogs were considered. We distinguished between following layers in the vertical structure of the zone of permafrost: thawed soil, frozen soil, water, ice, snow. We offer a simplified numerical algorithm for solving of onedimensional (in the vertical direction) heat conduction problems with moving boundaries of phase transition with the formation of new and cancellation of existing layers.

Выделяются следующие слои в вертикальной структуре зоны вечной мерзлоты: талый грунт, мерзлый грунт, вода, лед, снег. Предлагается упрощенный численный алгоритм решения одномерных (в вертикальном направлении) задач теплопроводности с подвижными границами фазового перехода с образованием новых и аннулированием существующих слоев.
The theoretical description of temperature fields in soils during freezing or thawing is carried out using solutions of Stefan's problem. We developed a mathematical model based on the equations of thermal conductivity for frozen and thawed layers. Those areas in which are lakes or bogs were considered. We distinguished between following layers in the vertical structure of the zone of permafrost: thawed soil, frozen soil, water, ice, snow. We offer a simplified numerical algorithm for solving of onedimensional (in the vertical direction) heat conduction problems with moving boundaries of phase transition with the formation of new and cancellation of existing layers.

Аннотация: The Yenisey basin had been famous for its fish richness for a long time, and the core of the fishery had been such valuable species as salmon, whitefish and sturgeon. However, the construction of the Angara-Yenisey cascade of hydroelectric power stations, domestic and industrial waste pollution, and intensive consumer catching played a huge role in changing fish habitats and the structure of ichtyocoenosis. The complex anthropogenic load eventually led to a reduction in stocks and a decrease in the natural reproduction of valuable and highly valued fish species. To preserve and restore natural populations of valuable fish species, it is necessary to increase the efficiency of reproduction, both natural and artificial. On the other hand, successful implementation of aquaculture plants is impossible without assessing fish stocks, their demographic status, habitat conditions and capacious information about the feed base. The aim of this research was to reveal the current development level of ichthyofauna and feed base in the Yenisey basin, and, on this basis, to assess the potential fish productivity and the maximum allowable volumes of introduction of juvenile fish as objects of artificial reproduction. In 2015, we carried out zoobenthos and ichthyofauna studies in the Yenisey and the rivers of its basin (Abakan, Mana, Kan, Agul, Kungus) (See Table 1). In the Yenisey, the material was collected from 5 stations in the upper reaches (the Republics of Tyva and Khakassia) and 10 stations in the middle reaches (from the dam of the Krasnoyarsk HPS to the mouth of the Angara River); in the tributaries of the Yenisey there were from 4 (Kungus River) to 10 (Mana River) stations. In the collection and processing of ichthyological and hydrobiological material, we used generally accepted methods. Zoobenthos samples were taken in watercourse ripals; fishing was confined to the sites of hydrobiological sampling. We assessed potential fish productivity based on the reserve of benthic feeding organisms’ production. The total biomass of forage organisms (zoobenthos) was calculated taking into account the area of the water body. The maximum allowable amount of immigration of juveniles (larvae) of artificial reproduction objects, which can be released into a water body, was determined based on the reserve of production of food organisms, as well as taking into account the yield to the fishery (the commercial stock replenishment factor) and the average mass of fish producers. In total, we carried out 54 control catches with fixed nets and 30 catches with drift nets. Ichtyocenoses were described according to Gadinov and Dolgikh (2008) and Zadelenov et al. (2004). This research presents the results of studying 175 zoobenthos samples and approximately 600 fish samples selected for a comprehensive biological analysis. In the benthic fauna of the investigated watercourses, lithoreophilic organisms predominated, they populated stony soils on a fast current. The basis of biomass in the upper reaches of the Yenisey and in its tributaries was mayflies, stoneflies and caddis flies; within the republic of Khakassia and in the middle reaches of the Yenisey, amphipods and chironomids took the lead (See Fig. 1). The Yenisei was characterized by a low biomass in the upper reaches (4.2 g/m 2 ) and the maximum biomass in the area from the Mainskaya dam to the city of Abakan (19.5 g/m 2 ), where Baikal-born amphipods develop in bulk. High values were found in the Mana and Kan Rivers (12.3 and 10.8 g/m 2 , correspondingly) with caddisflies’ domination. In the Abakan, Agul and Kungus Rivers, the biomass did not exceed 8 g/m 2 , on average, the main contribution was made by stoneflies (See Fig. 2). Grayling, dace and perch dominated in the studied areas in ichthyocenoses of the Yenisey; the tributaries of the Yenisey belong to the salmon-like type, the basis of the ichthyofauna was taimen, lenok and grayling (See Fig. 3). Since there are no obligate plankton eaters in the ichthyofauna of the investigated rivers, the potential fish productivity was calculated on the basis of the reserve of zoobenthos production. The upper reaches of the Yenisey and tributaries of the Abakan and Agul Rivers are characterized by the lowest potential fish productivity (less than 20 kg/ha) (See Table 2). In the Yenisey from the Mainskaya HPS to Abakan (Republic of Khakassia), the potential fish productivity reaches the maximum (96 kg/ha) due to the abundance of higher aquatic vegetation in the ripal of the river, which is densely populated by amphipods. However, food objects in macrophyte thickets are difficult to access for mass consumption by adult fish, so we did not take into account the fish productivity of the shallow-water zone when calculating the receiving capacity in this area. The total maximum permissible volume of introduction of grown-up juvenile fish (mainly taimen, lenok, grayling) into the studied watercourses for the purposes of artificial reproduction can reach 140 million pieces (See Table 3). The greatest receiving capacity (53 million pieces) is possessed by the Yenisey (on the area from the dam of the Krasnoyarsk HPS to the Angara River), the lowest by the Agul River and its tributary Kungus (5.4 and 2.3 million pieces, correspondingly). The received values of the permissible volumes of juvenile infestation of the studied watercourses give an idea that the fishery potential of the studied watercourses is very high. Nevertheless, to restore the population of fish valuable for the region through artificial reproduction, it is necessary to develop a whole range of measures, including the protection of aquatic biological resources and the rational organization of the fishery. © 2019 Tomsk State University.

Аннотация: In 2015, zoobenthos communities in the river Yenisei (upper and middle course) and in its tributaries (rivers Abakan, Mana, Kan, Agul, Kungus) was studied. All watercourses are mountain rivers, in the bottom fauna of which lithoreophilic organisms predominate, populating stony soils in a large current, at low water temperatures and favorable oxygen conditions. In zoobenthos, 231 species of macroinvertebrates were found, widely distributed in the Palaearctic and Holarctic regions. Dominant complexes were characterized by variability with the distance from river sources. In the river Yenisei benthos species composition expanded from the upstream (48 species) to the lower reaches (69 species). In the upper reaches of the Yenisei (area 1 - from the Kyzyl city to the city of Shagonar) the core of the benthic communities was represented by mayflies, caddis flies and chironomids. Downstream (area 2 - from the dam of the Mainskaya hydro power station to the Abakan city) the determining factor for the formation of the zoobenthos structure was the abundance of phytocenoses, where the Baikalian amphipods Gmelinoides fasciatus dominated. In the zoobenthos of the Middle Yenisei (area 3 - from the dam of the Krasnoyarsk Hydroelectric Power Station to the mouth of the Angara River), the chironomids took the leading positions. The quantitative distribution of the bottom fauna in the Yenisei was characterized by low values in the upper reaches (612 ind./m2and 4.2 g/m2) and high values in area 2 (5.5 thousand ind./m2and 19.5 g/m2). In the middle course of the Yenisei in area 3, the density of benthic communities (2.8 thousand ind./m2and 10.5 g/m2) is quite consistent with our earlier studies in the beginning of 2000s - 3.5 thousand ind./m2and 10.8 g/m2. In the tributaries of the Yenisei, the benthos species composition is more diverse than in the Yenisei; maximum values were in the rivers Mana and Kan (110 and 103 species, respectively). Bottom communities are represented predominantly by chironomids and mayflies, in the river Kan caddis flies complemented the quantity. The quantitative distribution of the bottom fauna in the tributaries of the Yenisei was heterogeneous. The smallest abundance (577 ind./m2) was recorded in the river Abakan, that belongs to the basin of the Upper Yenisei. The maximum abundance (2.8 thousand ind./m2) was found in the river Mana flowing into the Yenisei above Krasnoyarsk (basin of the Middle Yenisei). In the Kan River, which flows into the Yenisei below Krasnoyarsk, the abundance of benthos is comparable to its tributaries Agul and Kungus (1.2-1.9 thousand ind./m2). The distribution of biomass in the studied water streams depended on the taxonomic structure of benthic communities. The maximum values (10.1 and 12.3 g/m2) were found in the rivers of the Middle Yenisei - Man and Kan, and are associated with the dominance of caddis flies. In the rivers Abakan, Agul and Kungus biomass on average did not exceed 8 g/m2, while the contribution of stoneflies is higher than in other rivers. © SGEM2019.

Аннотация: Computational technology is developed for numerical modeling of wave fields generated by the electromagnetic pulse source "Yenisei" in blocky-layered geological media. Mathematical models of soils and rocks taking into account visco-elasticity and plasticity are applied. Algorithms of numerical implementation of these models are constructed based on the method of two- cyclic splitting with respect to spatial variables and physical processes. Parallel software for multiprocessor computer systems of cluster architecture is developed. We applied this technology to the analysis of frequencies and amplitudes of waves generated in the near-surface soils, and showed that the source "Yenisei" possesses the required seismic parameters. Given contribution presents the results of computation of seismic efficiency of the electromagnetic pulse source as the ratio of the energy passing through the reflecting surface in the depth of layered massif to the energy of pulse effect on the surface. The applied method is based on the analysis of the Umov-Poynting vector field obtained by means of high-performance computations. The results show that, by the criterion of useful seismic energy, pulse sources are not inferior to sources of vibratory type. © 2019 Author(s).

Аннотация: The northern territories of Eastern Siberia are characterized by a permafrost-taiga structure of the surface layer of soil, which reduces the efficiency of geological exploration using seismic sources of explosive and vibratory types. Therefore, Geotech Holding Company developed a special eco-friendly electromagnetic pulse source "Yenisei", which seismic waves are the subject of analysis using high-performance computing in this paper. Computational technology, worked out previously for solving the problems of the dynamics of viscoelastic, elastic-plastic, granular and porous media, is applied to the analysis of wave motion of a soil near a point of perturbations. It is shown that the main frequency of generated strain waves substantially depends on the elastic characteristics of a soil in the near-surface zone. A comparison of the results of computations obtained in the framework of the model of static loading with instant unloading and the model taking into account the monotone loading stage with subsequent pressure relief showed the validity of the hypothesis about the presence of added mass of a soil under the loading platform. This mass accumulates impact energy and emits seismic waves due to oscillatory motion. © 2019, Peter the Great St. Petersburg Polytechnic University.

Аннотация: The northern territories of Eastern Siberia are characterized by a permafrost-taiga structure of the surface layer of soil, which reduces the efficiency of geological exploration using seismic sources of explosive and vibratory types. Therefore, Geotech Holding Company developed a special eco-friendly electromagnetic pulse source "Yenisei", which seismic waves are the subject of analysis using high-performance computing in this paper. Computational technology, worked out previously for solving the problems of the dynamics of viscoelastic, elastic-plastic, granular and porous media, is applied to the analysis of wave motion of a soil near a point of perturbations. It is shown that the main frequency of generated strain waves substantially depends on the elastic characteristics of a soil in the near-surface zone. A comparison of the results of computations obtained in the framework of the model of static loading with instant unloading and the model taking into account the monotone loading stage with subsequent pressure relief showed the validity of the hypothesis about the presence of added mass of a soil under the loading platform. This mass accumulates impact energy and emits seismic waves due to oscillatory motion. © 2019, Peter the Great St. Petersburg Polytechnic University.
