This paper presents an analysis of the structure and geological history of the shelf of the East Siberian continental margin, based on the interpretation of seismic data in conjunction with geological information. The article describes the main structural elements of the East Siberian Sea which formed as a result of rifting processes (barremian–aptian) — the Novosibirsky, the Mansky, North Melvillsky and Dremheadsky rifts in the northern part of the East Siberian basin, and the Mellvillsky rift in the southern part. Rifts are considered together with volcanic zones and the main relative elevations — De-Long, Wrangel, Kotelnichesky and Baranovsky elevations. It is assumed that the process of rifting thinned out the crust of the Podvodnikov basin. The sedimentary basin was formed by rifting.
