Early to middle Holocene development of the Tsushima Warm Current based on benthic and planktonic foraminifera in the Nakdong River delta (southeast Korea)

Evolution of the paleo-Daesan Bay (Nakdong River, South Korea) as a result of Holocene sea level change

“…Their results showed that Holocene climatic and sea level changes controlled these geochemical signals, with higher pyrite contents during the period of maximum sea level and climatic optimum at a 14 C age of 6000-6700 cal yr BP. Similarly, based on the comparison of sulfur content and diatoms in Pleistocene and Holocene sediments from the Shibakawa lowland, northwest of Tokyo in central Japan, Koma and Suzuki (1988) revealed that sulfur content increases with increasing marine (Lim et al, 2015), ND01 (Kim et al, 2015;Cho et al, 2017;Takata et al, 2019), STP16-20 (Lim et al, 2019), and STP18-06 (this study). Yellow triangles in (D) indicate shell middens found around paleo-Daesan Bay.…”

“…1) (Cho et al, 2017). The appearance of both benthic foraminifera and warm-water planktonic foraminifera in the inner part of the Nakdong River delta suggests landward movement of benthic foraminifera and intensification of the Tsushima Warm Current in conjunction with sea level rise during the Early–Middle Holocene (Takata et al, 2019).…”
