The coastal image is widely manifested in various aspects of human activity, which is expressed in terms of aesthetic perception, cognition and preservation of natural and cultural heritage. “White Coast” is the figurative name of a wide strip of the right bank of the Volga River from the village of Zolotoye to Mount Durman in the southern part of the Saratov region, a unique natural and historical landscape. Such a perception of the landscape is primarily due to the predominance of upper Cretaceous and Paleocene sediments in the section (primarily the Turonian-Coniacian rhythmic strata composed of light carbonate rocks), exposed throughout the entire length of the Volga coastal ledge. The accumulation of significant geological, paleontological, archaeological and other objects in this area makes it possible to consider the territory as an interdisciplinary scientific and educational polygon, as well as an effective geoecotouristic cluster.

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.

The paper traces in stages the key trends and events in the history of the complex of scientific and educational areas which originated and developed in the Saratov Volga region largely due to the activities of V.I. Vernadsky’s students and followers. On the example of the most outstanding personalities, the influence of such personalities on features of the evolutionary dynamics of specific organizations, the city and the region is shown. Such an analysis allows us to see interregional interactions from a new perspective, the role of the region for the country, as well as to propose original scientific and educational projects for further study and popularization of V.I. Vernadsky’s heritage.

During ten field seasons, in the format of the scientific and educational expedition “Flotilla of Floating Universities”, whose concept is based on the synthesis of science and art, many researches and educational, volunteer and publishing projects and events have been implemented in the Volga region, the Caspian region, the Don region and the Urals. The research areas of the tenth field season in 2024 (Samara–Saratov Volga region) focused on: a) stratigraphic and astrochronological analysis of sections of Upper Cretaceous and Paleogene sediments, b) studying the role of living matter in the evolution of geoecosystems with special attention to biosimilar bodies (paleosoils, hardgrounds), c) analyzing the distribution of cosmic matter in natural environments in the zone of the “Saratov meteor shower” in 1918, and d) the history of the Great academic expeditions in the 18th century (the Volga routes of I.I. Lepekhin, P.S. Pallas, and I.P. Falk). The key scientific and educational projects were a field meeting of the RAS Commission for the Study of the Heritage of Outstanding Scientists (V.I. Vernadsky section) and a field session of the Moscow Society of Naturalists (MOIP) on the Volsk–Saratov section of the expedition’s main route.

For many decades, two main watercourses in the town of Volsk (Saratov region) have been serving the transit function of sewage effluents to the Volgograd reservoir. Sampling of bottom sediments was carried out along the length of the Verkhnyaya and Nizhnyaya Malykovka watercourses in order to analyze the specificity of the chemical composition of alluvial formations under technogenic impact conditions. The fraction of technogenic particles (plastics, coal, paint, synthetic fibers, etc.) was 4–20%. In terms of chemical composition, alluvium is represented by silicites with varying degrees of clay content., Bottom sediments are characterized as clay silicites, with the maximum content of heavy metals and organic matter (based on the value of loss on ignition) in the areas where wastewater enters the watercourses. The most typical contamination is with zinc, lead, and barium. The overall level of technogenic pollution of bottom sediments is high and can be named considerable in the upper reaches of the Nizhnyaya Malykovka watercourse only. In order to improve the ecological status of the watercourses, a set of measures is needed, including reconstruction and the creation of new infrastructure facilities of the urban environment.

The article presents the results of studies of a number of sections of Lower Cretaceous (Aptian) deposits in the Saratov Right Bank region (settlements Krasnyi Oktyabr’, Doktorovka, Kurdyum and Shirokoe), confined to the Yelshano-Kurdyum uplift. Oryctocenosis combines autochthonous (ichnofossils), subautochthonous (bivalves and gastropods) and allochthonous (ammonites, wood fragments) elements. Sedimentological and mineralogical indicators (ripple marks, desiccation cracks, wedge-shaped structures, cross-bedding, glauconite, and calcite veinlets), as well as fossil remains and features of their taphonomy, allow us to diagnose the coastal ecosystem of the epicontinental sea basin. In the ecosystem format, we see a variety of physico-geographical situations: areas of the bottom which are periodically actively bioturbated and hydrodynamically transformed into mature hardground; zones of active hydrodynamics with the formation of cross-bedding; and zones of subaerial surfaces with the possible development of stick soils. Reconstruction of the paleoecosystem is complicated by the presence of a number of natural facts that have not been unambiguously interpreted, images of which are given in the article. The studied sections are of interest from the standpoint of geoheritage. Selected natural facts are actively involved in the development of a number of geoscientific university museums.

The life and work of Professor Igor L. Vasilyev (1940–2019) is an illustrative example of the versatility of a? university geologist. As a native of Tambov City and a graduate from the renowned Saratov Higher Geological School during its peak (1950s–1960s), Professor Vasilyev spent the majority of his life working in Transbaikalia (Buryatia), researching Paleozoic and Proterozoic deposits in areas of hydrothermal ore genesis. Here, he put forward an original interdisciplinary concept of coevolution of synchronously developing volcanic systems and reef structures in the coastal zone of a marine basin with an output to ore formation. He worked as a researcher, a practical geologist, a teacher, and an organizer of the scientific and educational process. In the 1990s, after returning to his native Tambov City, Professor I.L. Vasilyev taught the course of engineering geology at The Technical University and actively engaged in museum work, organizing field trips and creating a set of educational collections, followed by the initial museum exhibition in the format of a geological cabinet. Currently, the museum cluster he established is being developed within the scientific and educational center “Coevolution of Geospheres Museum” of Tambov State Technical University.

This article continues the series of publications on the indicators of Holocene activation. Using the examples of the Volga and Amur rivers with their tributaries and the Razdolnaya River, the interaction of the river network with the Holocene orogenic system of the Alpine–Himalayan and Pacific mobile belts of Eurasia was studied. The river network is conformal to their orogenic system. Examples of the control of river valleys by shear systems of active faults are given. The influence of the rivers on the formation of erosional relief was studied. It is shown that loose sediments of the Mesozoic-Cenozoic rifts thrown up in the Holocene are actively destroyed by the river network, with a shear of up to many hundreds of meters. The rises on the riftogen framing and their internal rises, composed of strong pre-Mesozoic rocks, are weakly eroded. Many of them have a contrasting, nonequilibrium relief. The study was conducted within the framework of the pulsatingly expanding Earth model developed by the author.

The aim of our study was to carry out a detailed stratigraphic dissection of sections of the western territories of Kazakhstan using the remains of ichthyosaurs. Upper Jurassic and Lower Cretaceous ichthyosaurs were studied. Their collecting was carried out in the period of 2016–2023 from sections in the western Kazakhstan (the villages of Pogodayevo and Shchuchkino in the West Kazakhstan region, the village of Tushybek, Mangystau region (Central Mangyshlak Peninsula)) and the Middle Volga region (the village of Gorodishchi, Ulyanovsk region).

The article characterizes the reference sections of the Western region of the Republic of Kazakhstan with a description of the found remains of ichthyosaurs of the genera Kazakhstanosaurus, Nannopterygius, and Platypterygius. It has been established that fragments of their skeletons are found in the Upper Jurassic sediments of the sections near the villages of Pogodayevo and Shchuchkino in the West Kazakhstan territory, and in the village of Gorodishchi in the Ulyanovsk region, as well as in the sediments of the Lower Cretaceous of the Mangystau region. The species diversity of the genus Nannopterygius is noted.

Our study of the Upper Jurassic sections nearv. Pogodayevo, Shchuchkino and Gorodishchi, and the Lower Cretaceous section of nearv. Tushybek showed that the comparison of the identified Ichthyosaur genera with the Mesozoic scale complexes allowed accurate determination of the age of local stratons and the position of their boundaries.

2024 marks the 140th anniversary of the beginning of the expeditions of the laboratory of the Botanical Garden of Moscow University under the supervision of Professor Ivan Nikolaevich Gorozhankin to study the Central Russian flora. The historical and scientific context of the studies of this traditional object for the Botanical Garden of Moscow University during the 18th – early 21st centuries is traced. It is shown how the long-term targeted field research by the staff of the laboratory of the Botanical Garden has contributed to a methodologically unified approach to the organization of the program for studying the flora of the Oka River basin allowed not only to expand the territorial coverage, going beyond the purely Moscow region, but also to significant contribute to the development of an important scientific problem, namely, the cognition of the phenomenon of the Oka River flora. Gorozhankin’s principle of systemic research of regional flora was successfully implemented at the end of the 20th century by scientists of the Botanical Garden of Moscow University in the study of the flora of Central Russia.

As part of MSU’s Strategic Development Programme, the Youth Museum initiative is currently under development as a mobile-network project. The project consists of a system of interacting nodes, comprising a central site on the MSU campus and a network of regional subdivisions. The proposal suggests the use of mobile field museum exhibitions as an effective mechanism of interaction. In recent years, the aforementioned system was experimentally tested within the “Flotilla of Floating Universities” scientific and educational expedition. This project comprises a set of interrelated research, educational, training, artistic, and other projects. The direct and active involvement of students and schoolchildren led to the development of creative methods for the traveling exhibitions «Ancient Lukomorye» and «Living Matter in Geospheres», as well as to the methods of joint empirical and information gathering for the development of central and regional «Youth Museum» clusters. Materials were collected to create pilot versions of exhibitions, educational collections and the launch of interactive platforms at Tambov State Technical University: «Cretaceous Beach» («Palaeoecological Sandbox»), «Page of the Stone Chronicle» («Dissecting Table of a Beginner Palaeoecologist»), and others. These exhibitions are designed to ensure that they can be used effectively in educational and outreach activities on a wide range of topics. Students and schoolchildren will have the opportunity to conduct small-scale individual and collaborative research projects of varying levels of complexity using the platform format.

To mark the 160^th 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”.

A popular science film “Brotherhood of Scientific Creativity. Floating University named after Vladimir Vernadsky” was shot to the 160^th anniversary of the birth of Academician V.I. Vernadsky. Work on the film was carried out during 2022–2023 as part of the activities of the scientific and educational expedition «Floating Universities Flotilla» (the field work regions being the Middle and Lower Volga river, Don river, Caspian sea). It includes the original projects “Academician Vernadsky’s Floating University” and “Floating mobile-network museum center”. The concept of the project basically provides for interdisciplinary research on a wide range of problems of the interaction of geospheres and the evolution of geoecosystems, which is being implemented by creative teams of scientists from various fields and students with the active involvement of the local population in interactive museum practices. According to the main message of the film, it is in such an environment of “scientific creativity”, in the format of field natural sciences, that the development of the ideological heritage of V.I. Vernadsky on the principles of the “Priyutinsky Brotherhood” and maturation of the “new Vernadskies” from novice researchers. The original system of scenario and producer’s decisions included the contrast of images «academician–student», a series of episodes of actual field research (the study of geological sections, the phenomenon of lithophagy, natural and anthropogenic objects) with the implicit inclusion of the “young Vernadsky” in the process (the character is an actor) and subsequent the culminating meeting of the “two Vernadskies” (montage) against the background of the Volga river – a symbolic handover of the baton of “scientific creativity” to a new generation.
