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.

A number of interactive visitor interaction mechanisms are proposed within the format of a natural science university museum. A pilot project, tested at the Earth Science Museum of Moscow State University, provides the opportunity to immerse its visitors into the main exhibition using simple VR technologies, including 3D filming of the search and recovery of future museum objects during expeditions. The content of the new exhibition, in particular, consists of appropriately processed episodes of popular science films shot by the “Floating Universities Flotilla” expedition along the Volga, Don, and Caspian regions. In addition to the regional connection to the hall’s theme, links to specific exhibits and locations are provided; video segments are dedicated to the history of the search and selection of a particular exhibit (or their series) located in the hall, as well as the specifics of the location and research area of the expedition. Thus, visitors have the opportunity to participate in a virtual field trip, whose product, in the form of exhibits, is displayed in a specific museum hall. In addition to the permanent, stationary virtual cluster, a mobile version of the project presentation has been developed, which was tested at the 2024 All-Russian Science Festival at Moscow State University. To this end, the Earth Science Museum’s portable pavilion was equipped with virtual glasses, which allow festival visitors to “go on an expedition” along the routes of the “Floating Universities Flotilla,” “visit” the find sites, participate in the discovery and recovery process, and load them onto a research vessel. The virtual project’s creators—winners of the All-Russian "Youth and Museum" competition—served as guides and companions on the virtual field route. In 2025, as part of the “Floating Universities Flotilla” scientific and educational expedition, 360° video production was conducted along a predetermined route plan through natural sites to select potential museum exhibits.

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.

Expedition work is an important aspect of the activities of any natural science university museum, starting directly from its formation as a scientific, educational and enlightening center. As the museum structure develops, the role of such expeditions is transformed, acquiring the character of an evolutionarily necessary structural and functional mechanism. In the 75-year history of the Earth Science Museum of MSU, three main stages of expeditionary activity are distinguished. The first one is associated with the formation of the Museum in the 1950–60s and reflects, as the main task, the formation of an array of naturalia (natural objects), as well as photographic materials and works of art, which formed the basis of the exposition and collection base. The second stage is marked by targeted expeditions for specific local exhibition and research tasks, involving field collection of natural facts. At the third stage in the 21st century, the functional spectrum of the Museum’s expeditionary activities is expanding: field work, in addition to the traditional mechanism of new acquisitions, becomes an arena for positioning the Museum for the general public outside its classical space, an interactive cluster of education and popularization of science, involving various social groups in the area of the expedition’s work in museum co-creation. The Museum’s expeditions are widely reflected in popular science films and books, at “Science Festivals”, in the media space and blogosphere. These innovations have been testing in recent years in the mode of the scientific and educational expedition “Floating Universities Flotilla” in the Volga region, which has become an important resource for the implementation of the concept of a mobile network museum, as well as the formation of a youth museum as a promising interdisciplinary project of the Earth Science Museum of Moscow State University.

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.

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.

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”.

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 reason for writing this article was the off-site meeting of the museology section of the Moscow Society of Naturalists on December 22, 2022, to get acquainted with the exhibition «Past and Present of the Fauna of the Vladimir Region» permanently operating in the House of Culture in Strunino. The initial task of the paper was to analyze the situation with the moving to a new location of the well-known scientific, educational and entertainment museum «Ice Age» in Moscow. The museum was established in 2004 on the basis of the richest paleontological specimens collected by F.K. Shidlovsky National Alliance during multiple expeditions to the northeast of Yakutia, Chukotka, Altai and the Southern Urals. In 2004–2014, the museum functioned as a scientific and exposition center in pavilion No. 71 at the All-Russian Exhibition Center, which not only popularized knowledge about the animals of the Ice Age, but also provided unique exhibits for research by paleontologists. After several years of searching, the creator of the museum finally found a suitable place to accommodate large exhibits. It was necessary to decide how, by continuing the comprehensive educational and research activities, to ensure a wide attendance of the museum in a place remote from Moscow. Thorough studying of the information showed how much the task is broader and more serious than it seemed at first glance. The activity of an outstanding energetic person, devoted to a significant social goal, turned out to be connected with roots deeply rooted in the historical past of the country. Support for a specific undertaking has become important for the implementation of a comprehensive project of the museum, cultural, scientific and educational nature, up to the prospects for the development of the region. And at the same time, the identified problem can be considered as an example of a person’s involvement in the history of the country and responsibility for his/her actions.
