Radiolarians under the seasonally sea-ice covered conditions in the Okhotsk Sea: flux and their implications for paleoceanography
Y Okazaki, K Takahashi, H Yoshitani… - Marine …, 2003 - Elsevier
Four time-series sediment traps at two stations and three piston cores from the Okhotsk Sea
were quantitatively examined for coarse-sized radiolarian shells (> 63 μm). Traps were
deployed at 300 m and 1550 m at Station M4 (53° 01′ N, 145° 30′ E) and at 300 m and
700 m at Station M6 (49° 30′ N, 146° 28′ E) during August 1998 through May 2000. The
chronologies of the piston cores were established applying δ18O and paleomagnetic
intensity variations; they provide records extending back to marine isotope stage (MIS) 5.51 …
