| Abstract: | The diversified analysis (data on radiocarbon ages, diatoms, planktonic and benthic foraminifers) of sediments from the central
part of the Sea of Okhotsk (core from a depth of 1186 m) made it possible to define five sedimentary units corresponding to
five marine oxygen-isotope stages MIS 5-MIS 1 (the last 120 ka) and provide their thorough paleontological characteristic,
using different microfossil groups. Microfossil assemblages demonstrate variations in their abundance, distribution of individual
species, and representatives of different ecological groups through the section. |
