Tracing out the changes of the natural environments of the Arctic regions of Russia, as well as their influence on the formation of sediments and accumulation of mineral resources in them, is the key task of the environmental study. The Quaternary interglacial stages, including Marine Isotope Stage 5 (MIS-5), are of particular interest for the study, which contributes to the construction of analog climate models for the future. The paper discusses the MIS-5 depositing conditions in two climatically different areas: Chukotka, where there were no ice covering and the glacioisostatic effect in was insignificant for estimating sea level fluctuations, and Alaska, where the glacioisostatic effect was manifested. Besides, the stratigraphic volumes of the Pelukian and Valkatlenian formations are estimated as well as their correspondence to MIS-5.
