Online first (OF) is the advance electronic publication of accepted articles that will be posted in upcoming issues. OF articles cannot be changed (including title, authors, etc.) or withdrawn (without regard to violation of publication ethics). Such an online publication differs from a traditional one in that it does not have fixed page numbers and is not tied to a specific journal issue. However, each such publication has a digital DOI identifier or EDN number for correct citation and is indexed by databases in the usual manner. That is, the article can be fully used in the lists of references and indicated in the reporting documents.
After the formation of the printed version of the volume, the missing information is added to the articles, but the URL address of the article and DOI or EDN number are not changed.
Advantages of Online First:
Online First articles are posted in Russian and English as they are approved by the editor-in-chief and as the editorial process is completed.
When citing an Online First article, you must include the author's name, article title, journal title, year of publication, and DOI or EDN number. Example of the citation format:

The scale of the environmental problem associated with the pollution of vast areas of industrial zones in the oil industry is significant and requires the use of new technological approaches in solving it. A developing technology in this field is the use of electrochemical remediation, i.e., the removal of petroleum products and associated aqueous contaminant solutions from environments using low-voltage electric currents. The advantage of this method is the purification of both the surface fertile soil and the deeper soil layers. A current trend in the deve-lopment of electrochemical remediation methods is their integration with other remediation technologies, which increases remediation efficiency through oxidation or pollutant extraction, as well as significantly reduces the time required for remediation. This work is devoted to combining the treatment of oil-contaminated soils with direct electric current with the adding of the oxidizing component, calcium peroxide. The creation of a reactive geochemical barrier made of calcium peroxide in the interelectrode zone is proposed. This barrier will act as an inductor of oxidative reactions that promote the gradual mineralization of petroleum hydrocarbons. The formation of a directed contaminated electrophoretic flow moving from the anode to the cathode through a layer of calcium peroxide is simulated under laboratory conditions, and the characteristics of the purification process are investigated. The dynamics of such important environmental parameters as voltage, acidity of the treated medium, volume of the generated electrophoretic flow and the content of petroleum products in the solid (soil) and liquid (water) phases after cleaning are studied.
The accumulation of petroleum sludge in port facilities constitutes a significant environmental liability due to its high viscosity and complex management. This study evaluates the technical feasibility of using this waste as the main binder in the formulation of a cold asphalt concrete, combining it with endogenous aggregates (serpentinites from nickel industry rejects and vitric tuffs) for road maintenance in Moa, Cuba. A physical-chemical characterization of the materials was carried out, and asphalt mixtures with sludge contents of 8.0; 8.5, and 9.0 % were designed. Twenty-four specimens were fabricated using Marshall compaction, and their properties (density, stability, and deformation) were evaluated according to Cuban standards. After applying statistical quality control (rejection of specimens with > 10 % deviation), the experimental results demonstrated that curing time is a determining factor. After 45 days of curing at room temperature, the optimal mixture (8.5 % sludge) developed a Marshall stability of 7.32±0.21 kN and a deformation of 3.38±0.15 mm, satisfactorily complying with the quality indices of Cuban standard NC 54-18:1985 for dense mixtures. Environmental leaching tests confirmed the encapsulation of contaminants. This approach offers a sustainable technical solution for road infrastructure and contributes to the circular economy through the valorisation of industrial waste.
The article presents the results of experimental and methodological work on the use of magnetotelluric sounding in the area of the Russian Progress Station (Princess Elizabeth Land, East Antarctica). The research was accomplished by a field team from the Saint Petersburg Mining University in the course of the 71st Russian Antarctic Expedition (2025-2026) and is a continuation of the comprehensive geological and geophysical studies of East Antarctica. The main focus is on the practical application of the method in high polar latitudes. Issues related to ensuring the operability of the equipment, fieldwork logistics, and the influence of physiographic conditions on measurements are considered. The study of the geological structure of the Antarctic continent is complicated by the occurrence of a thick ice sheet which ensures the leading role of geophysical methods in solving this problem. The article presents the results of practical application of the Russian Nord electrical prospecting hardware-software measurement system and the Canadian MTU-5A together with preamplifiers designed to compensate for a high grounding contact resistance. The experimental and methodological survey line is laid across the Amery lineament, a large linear magnetic anomaly extending sublatitudinally for over 500 km. A comprehensive interpretation of magnetotelluric data and the anomalous magnetic field was accomplished. A resistivity section was constructed using a two-dimensional inversion, and a direct problem for the magnetic field was solved. As a result, a model is proposed for the structure of the Proterozoic suture zone, the rocks of which create a positive anomaly in the magnetic field. In the resistivity section, the anomalies with increased conductivity at depths below 10 km correspond to this structure. The obtained data create new opportunities for studying the deep structure and geodynamics of the East Antarctica.
