Seismoacoustics in Arctic seas: fundamental principles for improving monitoring technologies

The results of the development of scientific foundation of technology for passive geohydroacoustic monitoring of Arctic seas are presented, including theoretical studies of the conditions for the origin and propagation of wave fields generated by induced geodynamic processes in the layered structure “lithosphere – hydrosphere – ice cover”, the solution of a separate class of problems within the framework of a fundamental scientific problem, related to the search for innovative, environmentally safe geophysical technologies to outline the local heterogeneities, as well as the creation of prototypes, laboratory and full-scale testing of prototypes of new generation ice-based geohydroacoustic buoys. The method for estimating parameters of floating ice (thickness, density, Young’s modulus, Poisson’s ratio) in passive mode was proposed and tested in a field experiment. Particular attention is paid to the state of scientific and practical groundwork regarding the possibilities of developing methods for passive geohydroacoustic monitoring of the Arctic seas.
