Summary The challenges of modern oceanography are complex and multifaceted. The task of synthesizing a universal apparatus that would cope with all the difficulties is extremely difficult. For an optimal solution to the problems facing this area, it is necessary to use multi-agent complexes of robotic systems. As a result of the analysis of the available devices, their functions, the tasks they perform, as well as highlighting the patterns of their use, we have proposed two typical scenarios for the use of a multi-agent complex. The existing backlog of NPP PT Okeanos JSC, as well as many years of experience in the development and operation of marine robotic systems allow developers to be confident that with the proper level of support from potential customers, the application concepts described by the authors are feasible in practical realities, and not only on paper and the results of theoretical calculations.

Summary The article proposes mathematical models for calculating induced polarization (IP) when solving 3-D airborne time-domain electromagnetic problems. The proposed approaches are optimized directly for solving “multisource” problems for further application in data processing systems. For constructing finite element approximation, we use optimized non-conforming hexahedral meshes allowing to drastically reduce the number of degrees of freedom while keeping the required solution accuracy. In addition, to provide calculations with a large number of positions of the transmitter-receiver set, the space-time grouping of subtasks corresponding to different positions of the airborne system and parallelization were used. We present a comparison of the developed computational schemes that perform calculations both directly in the time domain and in the frequency domain, as well as a comparison with the results of other authors. It is shown that the solutions obtained using different approaches are in good agreement with each other. The computational costs required for calculating the electromagnetic field taking into account the IP effects in a complex 3-D medium with topography are about 10 s per position. This will make it possible to use this approach in the future in systems for processing airborne data.

Summary The goal is to assess the possibilities of electrotomography for the study of heavy oil deposits. The main object of study is the largest tar sand deposit - Alberta (western province of Canada).There are some problems with the production of such oil: 1) Reservoir heterogeneity associated with interlayers of clays and shales. This is a significant obstacle to vertical vapor migration; 2) watercut zones. Based on this, the following tasks arise before the electrotomography: 1) Select tar sand layers and estimate their thickness; 2) Select the conductive horizons (clay, shale, water) that may be present in the oil-bearing strata. The assessment of the capabilities of electrotomography was carried out using simulation with subsequent inversion. Models were created to match the geological structure of the region (Alberta, Canada). Comparing the results of solving the inverse problem (inversion) with the starting model gives this estimate. In the process of modeling, a pole-dipole + dipole-dipole electrotomography unit was used.

Summary Based on the permafrost study, we analyze data of the method of reflected electromagnetic waves (MREMW), including both kinematic characteristics of the section and attenuation features, determined by conductivity. The highly inhomogeneous structure of the upper permafrost is shown on a normalized conductivity section and compared to the near-field transient electromagnetic sounding data. The spatial resolution of MREMW is higher than for traditional electric prospecting and corresponds to the resolution of deep GPR. The MREMW penetration depth in the high conductive salty medium with thawing boundaries reached over 40 meters.

Summary The main object of seismic and acoustic research during construction is a rock mass, which is understood as a separate part of the geological environment, located in the sphere of engineering influence. This part of the environment is investigated in order to establish the conditions for the construction work and the subsequent operation of the erected structures. Identification and assessment of the formed weakened zones in the host massif is a necessary stage in predicting subsequent precipitation and deformations of engineering structures located in the zone of influence of construction works. The results of geophysical studies are the basis for the development of measures to eliminate adverse factors and processes in the soil mass, and also serve as an important tool for monitoring the effectiveness of measures already taken.

Summary The paper presents the results of micromagnetic and georadar surveys at quarry of the Belousovsky mine. As a result of geophysical studies, it was revealed that local positive magnetic anomalies are observed along the sides of the ancient quarry of the Belousovsky mine. These anomalies are associated with soils excavated from the quarry. According to the GPR data, the bottom topography of the ancient quarry was determined during its operation in the Bronze Age, and a three-dimensional model of the mine was built. Based on the results of the study, it is possible to estimate the number of excavated soils and the amount of ore mined. GPR, micromagnetic survey, Belousovsky copper mine, Bronze Age

Summary The article shows the results of three-dimensional inversion of electrotomographic data obtained on the heap leach ore pile. The main purpose of the study has to identify filtration channels inside the heap, dry ore blocks and leaks through the waterproofing layer. The array of 3-D data was obtained from the 2-D dataset. 3D inversion was performed and sections and electrical resistivity maps were constructed. Anomalies of electrical resistivity associated with two filtration channels were identified. It is shown that low-permeability zones have formed under technological roads, which were detected by anomalies of increased electrical resistivity. They disturb fluids streaming. According to low electrical resistivity local anomalies, the position of leakage sites in the waterproofing layer has detected.

Summary The article describes software solutions that improve and accelerate both the process of field operations by the SWSR method and the stage of seismic data processing. The developed EJ program controls the TELLS-3 data acquisition software, allows keeping the field log, saving the geometry and features of the survey system. The FastMineProc program designed to calculate geometry using the information from the tables created by the EJ program and to perform express processing of data by the SWSR method. The main feature of the program is the presence of two specific procedures - the separation of reflections and the combination of sections for the upper and lower half-spaces into a combined section. Further developments will be aimed at obtaining a consolidated depth section directly during field works.
