“…Marine tephra sequences offshore of Kamchatka, by contrast, provide continuous records of its pre-Holocene explosive activity (e.g. Prueher and Rea, 2001;Gersonde, 2012;Derkachev et al, 2016). In addition, these sequences have good potential for the development of a regional tephrochronological model applicable for paleoceanographic studies.…”

“…In recent years, a number of papers have considered selected tephra layers found in marine cores around Kamchatka (e.g. Ponomareva et al ., ,, ; Derkachev et al ., , ), although only one attempt has been made to geochemically analyze a long and continuous tephra sequence to the east of Kamchatka, downwind from its volcanic arc (Cao et al ., ). The latter authors geochemically characterized many tephras from four cores of the Ocean Drilling Program (ODP) Leg 145 Sites 881–884, located in the NW Pacific ~700 km downwind from the Kamchatka volcanoes.…”

This paper presents the first detailed study of a late Pleistocene marine tephra sequence from the NW Pacific, downwind from the Kamchatka volcanic arc. Sediment core SO201-2-40, located on the Meiji Rise~400 km offshore the peninsula, includes 25 tephras deposited within the last 215 ka. Volcanic glass from the tephras was characterized using single-shard electron microprobe analysis and laser ablation inductively coupled mass spectrometry. The age of tephras was derived from a new age model based on paleomagnetic and paleoclimate studies. Geochemical correlation of distal tephras to Kamchatkan pyroclastic deposits allowed the identification of tephras from the Karymsky, Gorely, Opala and Shiveluch eruptive centers. Three of these tephras were also correlated to other marine and terrestrial sites and hence are identified as the best markers for the north-west Pacific region. These are an early Holocene tephra from the Karymsky caldera (~8.7 ka) and two tephras falling into the Marine Isotope Stage (MIS) 6 glacial time: an MIS 6.4 tephra from Shiveluch (~141 ka) and the MIS 6.5 Rauchua tephra (~175 ka) from Karymsky. The data presented in this study can be used in paleovolcanological and paleoceanographic reconstructions. recovered from core SO201-2-40 on the Meiji Rise (NW Pacific) (Fig. 1). The record includes 25 tephra layers and lenses deposited during the last~215 ka. We present an age model for the core based on paleomagnetic and stratigraphic

“…Hypersthene mainly occurs in volcanic eruption material, and volcanic debris minerals are distributed throughout the entire sea, it is rich in some of the volcanic ash layers (Hasegawa et al, 2011). For example, the KO volcanic ash layer covers almost the entire Okhotsk Sea, and the K2 volcanic ash layer (Nemo Volcanic eruption, Nemo-III caldera, Onekotan Island) is distributed around the eastern coast of Sakhalin Island (Derkachev et al, 2016). The hypersthene contents of these ash layers are very high, especially that of the K2 layer (Wang et al, 2017).…”

The Okhotsk Sea is a distinctive marginal sea in the northwestern Pacific Ocean, which is characterized by the prevalence of seasonal sea ice in winter. Sediment is sourced from the around region through sea ice transportation, rivers input, and volcanic eruptions. Surface sediments of the Okhotsk Sea shelf vary greatly in grain size, and the sand content is generally high, which is conducive to source-to-sink studies using ice-rafted detritus (IRD),detrital minerals and single mineral geochemistry methods. In this paper, the 63–125 μm grain size fraction was selected for the detrital minerals analysis of surface sediments (top 0–10 cm) from 58 sediment stations and 15 stations samples has been chosen for garnet chemistry. These stations are mainly located in the south central Okhotsk Sea. The distribution and composition of the heavy minerals are influenced by material derived from the Amur River, the north shelf (Okhotsk-Chukotka volcanic belt), Sakhalin Island, the Kamchatka Peninsula, and the Kuril Islands. The detrital mineral results show that hornblende, epidote and garnet are terrigenous material indicators. High contents of fresh hypersthene can be used as an indicator of volcanic eruption materials. And high content of abraded hypersthene can be used as an indicator of Okhotsk-Chukotka volcanic materials. In the northern Okhotsk Sea, the southward moving sea ice produced in Sakhalin Bay collides with the sea ice produced off the east coast of Sakhalin Island, which causes the sea ice to accumulate to the southeast. This results in the deposited ice-rafted debris having a southeastward facing fan shape, and the geochemical analysis of the garnet supports this conclusion. From west to east, the amount of material from Sakhalin Island gradually decreases, while the amount of material from the Amur River and Chukchi-Kamchatka increases.
