Description
Summary:Distribution of diatoms, radiolarians, planktonic and benthic foraminifers, and sediment components in fraction >0.125 mm was analyzed in a core obtained from the central Sea of Okhotsk within frameworks of the Russian-German KOMEX Project. The core section characterizes the period 190-350 ka, which corresponds to marine-isotopic stages (MIS) 7 to 10. During glacial MIS 10 and MIS 8, the basin accumulated terrigenous material lacking microfossils or containing them in low abundance, which reflects, along with their composition, heavy sea-ice conditions, suppressed bioproductivity, and bottom environment aggressive toward calcium carbonate. Interglacial MIS 9 was characterized by elevated bioproductivity with accumulation of diatomaceous ooze during the climatic optimum (328 to 320 ka). Water exchange with the Pacific was maximal from 328 to 324 ka ago. Environment became moderate and close to the present-day one at the end of the optimum exhibiting possible existence of a dichothermal layer with ... : Supplement to: Barash, Max S; Matul, Alexander G; Kazarina, Galina Kh; Khusid, Tatyana A; Abelmann, Andrea; Biebow, Nicole; Nürnberg, Dirk; Tiedemann, Ralf (2006): Paleoceanography of the central Sea of Okhotsk during the Middle Pleistocene (350-190 ka) as inferred from micropaleontological data.
