“…Our records emphasize the different responses to sea level and monsoon changes in the interior JS during HS1 (Shi et al, 2019;Dong et al, 2021). Sea level rise induced the enhancement of ventilation, hydrologic sorting, and change of provenance in the southern JS during HS1, but it had a smaller impact on the paleoenvironmental evolution of western JS compared to that of EAM.…”

“…The abrupt increase in planktic foraminifera δ 18 O values indicated the inflow of relatively saline and cold water from the East China coast into the JS through the Tsushima Strait during HS1 (Domitsu and Oda, 2006). Redox-sensitive elements, radiolarian proxies, and reappearance of benthic foraminifera suggest that deep-water ventilation was enhanced in the eastern and centeral JS (Domitsu and Oda, 2006;Zou et al, 2012;Dong et al, 2020;Dong et al, 2021). In addition to the provenance change documented in core KCES1 (Zou et al, 2021), this evidence demonstrated that an intrusion of paleo-TWC into the JS due to the reopening of the Tsushima Strait during HS1.…”

“…Under the influence of the Liman Cold Current (LCC) and the formation area of the Japan Sea Proper Water, the western JS sediments recorded the growth and decay of sea ice and evolution of the EAM (Gorbarenko et al, 2014;Shi et al, 2019;Dou et al, 2020;Dong et al, 2021). Sea-ice coverage expanded southward significantly during the LGM and melted intensely as a result of boreal insolation rising during the Last Deglaciation (Ikehara, 2003).…”

The Sea of Japan (JS) is a unique marginal sea in the western North Pacific that is characterized by four shallow straits. It can provide information about the paleoenvironment, for instance indicating variations in the East Asian Monsoon, Tsushima Warm Current, sea ice coverage, and Westerly Jet. Compared with other marginal seas in the western North Pacific, the JS is currently the only marginal sea without influx from large rivers. It is, therefore, of interest to determine the source of terrigenous sediments over time, particularly in the western JS, which has been less investigated in previous reports. In this study, a suite of multi-proxies including Sr and Nd isotopes and minor elements were measured for fine fractions (<63 μm) of core LV53-18-2 that were recovered from the western JS over the last 30 ka. Our results show that the sediments are rich in volcanic detritus and that the provenance of terrigenous sediments in the western JS is mainly derived from the arid region in northern China and coastal areas in the Far East. During the Last Glacial Maximum, the increased coverage of sea ice may have contributed to the accumulation of terrigenous debris. Meanwhile, the stronger East Asian Winter Monsoon and expansion of the Westerly Jet over northern China also carried more dust to the study area. However, the weakened atmospheric circulation and rise in sea level, induced by the ascending boreal insolation during the last deglaciation and early Holocene, remarkably reduced input of terrigenous debris, and the intense melting of sea ice delivered an amount of detritus from coastal areas to the research area. After 8 ka, the high stand sea level and opening of the Tatar Strait may have led to the development of the Liman Cold Current, which transports large quantities of volcanic materials to the study area continuously and produces more positive Eu anomalies, radiogenic εNd, and depleted ΣREE.

Holocene Tephrostratigraphy in the East Sea/Japan Sea: Implications for Eruptive History of Ulleungdo Volcano and Potential for Hemispheric Synchronization of Sedimentary Archives

Active volcanic centers in East Asia have huge potential to pose major volcanic hazards on modern human society. The area around the East Sea (Japan Sea) is one critical element of this, with a population of ca. 200 million along the Korean Peninsula and the Japanese Islands at risk from volcanic hazards. The Ulleungdo in the East Sea (Figure 1) is one of such hazardous volcanoes, which is responsible for one of the largest Holocene eruptions in East Asia (Machida et al., 1984). Ash from the eruption (U-Oki) blanketed large areas of the East Sea and reached
