New data on seismic stratigraphy and palaeogeography of the East-Siberian Sea

Five seismostratigraphic strata (SSS), which can be correlated with different stages of the evolution of the area during the Pliocene – Quaternary, were identified, and their distribution in the mapped area was traced based on a comprehensive analysis of geological and geophysical data obtained during the expedition-2018, carried out by VSEGEI experts for the state map 1000/3 (water area of sheets R-57–60), literary and fund data and correlation with materials on the adjacent land. These data allowed significant refinement of paleoclimatic and paleogeographic reconstructions of natural setting in the Neopleistocene–Holocene within the coastal shelf of the East Siberian Sea. The new map of Quaternary formations at a scale of 1 : 1,000,000 was compiled for the water area.
