- Аннотация: Rich with fossil minerals, offshore areas of the Arctic region attract a lot of attention from researchers, which creates the necessity to investigate the structure of the subsurface space. This work is dedicated to the simulation of one of the standard methods used, which is seismic survey. The computational domain was constructed by taking into account the main features of the offshore areas: heterogeneous ice field, water, and layered ground with an oil reservoir. The linear elasticity model was chosen as the governing system of equations and solved using the grid-characteristic method on rectangle grids. Ice was simulated using the Maxwell viscoelastic model and the Kukudzhanov elastoviscoplastic model, taking into account the temperature dependence of its Young’s modulus. The results reconstruct different wave phenomena, such as Rayleigh waves, Scholte waves, reflected from the reservoir wave front, and seismic ghost reflections, which can be used for the analysis of the structure of geological layered media.
