Abstract—Deep seismic surveys along profile 5-AP were carried out in the northeastern shelf zone of the Arctic from the Chukchi fold region on the continent to the deep North Chukchi Basin. To process the experimental material of this profile, mathematical modeling based on the time field method was used, as well as the method of migration of fields of refracted and reflected waves recorded at large distances from the source. As a result, with a high degree of reliability, it was possible not only to identify new features of the structure of the Earth’s crust and upper mantle of this region, but also to determine the rheological properties of the material making them up and the degree of its rigidity or plasticity. This made it possible to propose a new model of the possible geodynamic evolutionary history of this region.
