“…The last occurrences (LOs) of Amphimelissa setosa (Cleve, 1899) and Schizodiscus japonicus Suzuki, 2014 (Spongodiscus sp. in Matul et al, 2002), are all well-known, recorded at 0.07 and 0.29 Ma, respectively, in the Sea of Okhotsk (Matul et al, 2002). However, their first occurrences (FOs) in the North Pacific are poorly understood; Matul and Abelmann (2005) recorded the FO of A. setosa in the Sea of Okhotsk at 1.03 Ma, and Ikenoue et al (2016) assigned the ages of the FOs of A. setosa and S. japonicus in the Bering Sea to be 0.99 Ma.…”

“…We carefully examined several well-known bioevents identified by previous studies in the North Pacific (Matul et al, 2002;Kamikuri et al, 2004Kamikuri et al, , 2007Matsuzaki et al, 2014a, b;Ikenoue et al, 2016;Kamikuri, 2017 …”

“…A. setosa is an extant species in Arctic to subarctic area of the North Atlantic Ocean (Bjørklund et al, 2015;Matul and Abelmann, 2005). It seems that A. setosa has existed in the subarctic North Atlantic Ocean since the end of Marine Isotopic Stage 11 (MIS 11) (Bjørklund et al, 2015), and this species has disappeared from the North Pacific between the MIS 4 and MIS 5 (0.06-0.07 Ma) (Kruglikova, 1976;Matul and Abelmann, 2005;Matul et al, 2002Matul et al, , 2009. The FO of A. setosa was recorded at 1.03 Ma in the Sea of Okhotsk at Core LV28-42-4 (Matul and Abelmann, 2005) and the first continuous occurrence (FCO) of the representative species in the Bering Sea is 0.99 Ma (Ikenoue et al, 2016).…”

“…The biostratigraphic importance of S. japonicus was first pointed out by Ling (1973). The LO of S. japonicus was dated at 0.287 Ma in the Sea of Okhotsk (Matul et al, 2002) and at 0.37 Ma in the Bering Sea (Ikenoue et al, 2016); however, the FCO of S. japonicus was determined to be 0.99 Ma in the Bering Sea (Ikenoue et al, 2016). Since the FO of S. japonicus at Site U1417 is placed at 1.30 Ma (this study), these age differences might imply the existence of a diachroneity between the Bering Sea and the southern Gulf of Alaska.…”

“…Of particular interest in the retrieved cores are polycystine radiolarians, which are siliceous microorganisms that inhabit shallow, intermediate and deep waters (e.g., Renz, 1976;Anderson, 1983;Kling, 1979;Kling and Boltovskoy, 1995;Nimmergut and Abelmann, 2002;Okazaki et al, 2004;Suzuki and Not, 2015;Matsuzaki et al, 2016). Their skeletons composed of amorphous silica are generally well-preserved and abundant in the seafloor of the North Pacific, and the high levels of radiolarian preservation and abundance in deep-sea sediments of this region have facilitated numerous paleoceanographic and biostratigraphic studies (e.g., Hays, 1970;Kling, 1973;Foreman, 1975;Morley et al, 1982;Motoyama, 1996;Pisias et al, 1997;Matul et al, 2002;Kamikuri et al, 2004Kamikuri et al, , 2007Matul and Abelmann, 2005;Itaki et al, 2012;Matsuzaki et al, 2014aMatsuzaki et al, -c, 2015aKamikuri, 2017). According to onboard data, radiolarians were very rare in the Pliocene-Miocene sediments collected at Site U1417 (Jaeger et al, 2014).…”

Abstract. Expedition 341 of the Integrated Ocean Drilling Program (IODP) retrieved sediment cores spanning the time interval between the Pleistocene and Miocene from the southern Gulf of Alaska. Onboard Pleistocene radiolarian biostratigraphy is hereby refined by increasing the sampling resolution. The 178 core samples from the upper 190 m CCSF-B (Composite Core Depth Scale F-B) of Site U1417 contained faunal elements similar to the northwestern Pacific; for example, the three biozones in the northwestern Pacific (i.e., Eucyrtidium matuyamai, Stylatractus universus and Botryostrobus aquilonaris) were also recognized in the Gulf of Alaska, spanning 1.80-1.13 Ma, 1.13-0.45 Ma, and the last 0.45 Myr, respectively. Based on the age model that we used in this study and the shipboard paleomagnetic reversal events, the first occurrences (FOs) of Amphimelissa setosa and Schizodiscus japonicus in the northeastern Pacific were preliminarily determined to be 1.48 and 1.30 Ma, respectively. The last occurrence (LO) of Eucyrtidium matuyamai and the FO of Lychnocanoma sakaii, both well-established bioevents in the northwestern Pacific, were dated at 0.80 and 1.13 Ma, respectively. The LO of E. matuyamai is a synchronous event at 1.05 ± 0.1 Ma in the North Pacific, while the FOs of A. setosa and S. japonicus at 1.48 and 1.30 Ma, respectively, are significantly older than what has been found elsewhere.

A high-resolution abundance curve of the radiolarian species, Cycladophora davisiana, was obtained from a Late Pleistocene sediment core, PC-23A, which was obtained from the northern slope of the Bering Sea. The abundance pattern of this species was high during the glacial period and low during the Holocene. This general stratigraphic pattern was correlated with a previously reported pattern for the subarctic Pacific Ocean. However, planktonic foraminifera-based accelerator mass spectrometry 14 C dating revealed that a significant peak in the C. davisiana curve during the glacial period correlates to 15.5 ka, which is younger than that previously estimated as being the Last Glacial Maximum. The higher abundance of this species implies that there was well-ventilated water with a large amount of organic matter in the intermediate-water layer. An unusually high propagation of C. davisiana during the earliest Holocene period, Bølling-Allerød (B-A) and Dansgaad-Oescheger interstadial event # 12, was most likely related to a significant increase in the amount of organic matter released into the intermediate-water depths by a brine pump system via ventilation. In addition, centennial-scale variations in the abundance of C. davisiana during the B-A period suggest that the intermediate-water ventilation was sensitively affected by brine rejection during sea ice formation as well as large-scale atmospheric circulations such as the Arctic Oscillation.
