Biosphere, noösphere, and agriculture (to the 160th anniversary of the birth of V.I. Vernadsky)

The paper is devoted to the outstanding Russian scientist Vladimir I. Vernadsky, who is one of the founders of ecology. As a student of V.V. Dokuchaev, he developed his teacher’s ideas of a systematic dynamic approach to the study of nature and introduced a deep scientific ecological content into the concepts of the biosphere and the noösphere. V.I. Vernadsky is the founder of a complex of modern Earth sciences (geochemistry, biogeochemistry, radiology, and hydrogeology) and the creator of many scientific schools. In his scientific work, he covered many research areas, from geology to the study of the role of living matter in geochemical cycles, from soil science to the biosphere, the increasing influence of scientific thought, human activity in the biosphere and its transformation into the noösphere. The importance of agriculture in the biosphere and the noösphere is considered. The biosphere is an area of active life on Earth (troposphere, hydrosphere and part of the lithosphere), the composition, structure and energy of which are mainly due to the activity of living organisms. The noösphere is its thinking shell. Agriculture, whose most important part are grassland ecosystems, is an important component of the biosphere, being a reproducible, autotrophic sustainable resource (energetical, environmental, food and feed). In light of the pressing environmental problems facing the world, environmental education and environmental thinking are a priority for the development of the biosphere, the noösphere and agriculture.

Jan Stanislaw Franciszek Czerski (1845–1892) and studying Siberian mammals: on the 180th anniversary of his birthday

May of 2025 marks the 180th anniversary of the Siberian researcher, geologist and geo­grapher Jan Stanislaw Franciszek Czerski (1845–1892). However, he worked not only in the field of geology and geography. An important part in Czerski’s researches was works on paleontology and zoology; he is also known as an archaeologist. In 1871–1879, Czerski worked at the museum of the Siberian (Eastern Siberian) Branch of the Imperial Russian Geographical Society in Irkutsk. He studied, catalogued and significantly expanded the zoological and paleontological collections of the museum. The article provides brief information from Jan Czerski’s life. His main works on the study of modern and quaternary Siberian mammals, which laid the foundation for further research in this area, are analyzed. Czerski’s paleontological research ranks him among the outstanding palaeontologists of the second half of the 19th century.

Paleogene columnar stromatolites from the “Kamyshinskie ushi” location (Lower Volga Region)

The article discusses the results of our preliminary studies of Paleocene columnar stromatolites from the “Kamyshinskie Ushi” location, near the northwestern periphery of the town of Kamyshin. The morphology, composition and features of the buildings were studied. They can be attributed to the morphological type of columnar non-branching stromatolites; fan-shaped branching stromatolites are less common; their mineral composition differs little from the host rocks and consists mainly of quartz grains cemented by silicon oxide. Dark layers are much more saturated with ore inclusions. The concentration of chromium, molybdenum, wolfram, vanadium, cobalt and nickel in dark varieties increases noticeably, which confirms their stromatolite origin. The deposition settings of their formation remain controversial.

Thermal history of the permafrost formation in the sedimentary section of the Tyumen superdeep SG-6 well

The thermal evolution of the permafrost in the sedimentary section of the Tyumen superdeep SG-6 well has been numerically reconstructed using the ICE2020 software package, which is part of the GALO flat basin modeling system. The thermal evolution of the sedimentary strata in the last 3.5 My is considered as the final stage of the basin modeling, whose formation began with continental rifting in the Late Permian. Abrupt climate changes in the late Pliocene–Holocene led to a decrease in the rock temperature by 15–20°C in the upper 1–1.5 km of the SG-6 sedimentary section. The maximum thickness of the permafrost in the study area was about 711 m, reached 2.6 Mya. The maximum thickness of the permafrost for the last ice age (23–18 thous and years ago) was 412 m, reached about 14.5 thousand years ago. According to our modeling, the modern base of the permafrost is at the depth of 311 m and is degrading with the rate about 13 m/1000 y. The results of our calculations with a database of climatic data limited to the last 50 and 100 thousand years differ markedly from the modeling results with the complete database for the last 3.5 My.

Museum exhibition “Living matter in the geospheres” to the 160th anniversary of the birth of V.I. Vernadsky

To mark the 160th anniversary of V.I. Vernadsky's birth, Lomonosov Moscow State University has organized an exhibition based on the theme of “living matter”, which to a greater or lesser extent permeates all the geospheres of our planet, provides many mechanisms of interaction between the geospheres and links between the planet and the cosmos. Natural exhibits demonstrate peculiarities of the geochemical transformation of individual organisms and their communities during the transition from the biosphere to the lithosphere, the diversity of biocosmic bodies in the history of our planet, the possibilities of modern sciences in reconstructing geobiosystems of the past. The structure of the exhibition includes a number of special blocks containing original exhibits and information, namely: “Scientist’s Cabinet” with information about the life path, scientific directions and some students and followers of Academician V.I. Vernadsky (connected to him through Moscow University). The cluster “Co-evolution of the Biosphere and Lithosphere” with disclosure of the mechanisms of transition of living matter and integral ecosystems into the “stone record” of the Earth, the structure of the pedosphere in a broad sense, the diversity of biogeoprocesses and their products in the history of the Earth, the formation of “archives of nature” in the geospheres, the functioning of geobiodynamically active zones on the example of the East European Platform; the cluster “University’s Lukomorye”, reflecting peculiarities of coastal geo-ecosystems for the general public (on the example of the Paleocene of the Volga region). Most of the exhibits of the exhibition have been obtained during the scientific and educational expedition “Flotilla of Floating Universities” (2015–2022) from the Volga region, the Caspian Sea, the Don region and the Urals and are considered in the future as the basis for the development of a model polygon of the “MSU Youth Museum”.

Physical modeling of the formation conditions of marginal plateaux on the example of structures in the North Atlantic Ocean

Peculiarities of the formation of marginal plateaus in the early period of the opening of the North Atlantic Ocean are considered. The oceanic opening between Greenland and Europe (formation of the North Atlantic Ocean) began approx. 50–55 Mya after a long period of rifting, followed by the formation of the Aegir spreading ridge and the formation of the basin of the Norwegian Deep. Since that moment, the formation of a series of specific structures (marginal plateaus) began. The article considers conditions for their formation, using the physical modeling method. Three groups of structures were distinguished and typified according to the formation mechanism. A series of experiments was performed to each type of structures. Experimental results are compared with our proposed model for the formation and evolution of marginal plateaux.

Formation of the sedimentary cover of the South Kara basin

A scheme of formation of the sedimentary blanket of the South Kara basin is considered, which can further be used for numerical reconstruction of its thermal history. The scheme is based on our analysis of the literature information on the structure and geological history of the Barents-Kara region. This information included an interpreted seismic profile crossing the studied area, drilling data from four wells located along the profile (the University, Rusanov, Leningrad and Kharasavey ones), measurements of the heat flow and deep temperatures in the basin. The proposed scheme considers the formation of the basin as a series of sedimentation stages with various combinations of clay shales, siltstones and sandstones and sedimentation in the Cretaceous and Paleogene with their subsequent erosion in the Miocene. The erosion amplitude is estimated by the observed change in the porosity of sedimentary rocks with depth. The initial heat flow in such a model should correspond to the flow of modern axial zones of continental rifting or be lower for the areas remote from the corresponding segments of the Late Permian-Early Triassic continental rifting system.
