“…Little information is available about the paleoChangjiang and the paleo-Huanghe estuaries during the last glacial maximum, especially regarding river courses and river mouths. The paleo-Huanghe and the paleo-Changjiang estuaries may have been close to the northern Okinawa Trough and the middle Okinawa Trough, respectively, at that time (Diekmann et al, 2008;Dou et al, 2010a;Ujiié and Ujiié, 1999;Ujiié et al, 2001;Xu et al, 2014a). In contrast, Li et al (2005Li et al ( , 2014 pointed out that ancient river channel systems of the paleo-Changjiang during the last glacial maximum may be buried beneath the modern Changjiang estuary (about 30-32°N, 125-125.5°E).…”

“…Most riverine sediments are trapped in estuaries and/or deposited on adjacent shelves Liu et al, 2004Liu et al, , 2007bMilliman et al, 1985), but others are transported to the Okinawa Trough, resulting in the formation of a thick sedimentary deposit (Dou et al, 2010a(Dou et al, ,b, 2012Katayama and Watanabe, 2003;Qin et al, 1987;Tada et al, 2013;Xu et al, 2012aXu et al, ,b, 2014a. The source-to-sink process of terrigenous matter into the trough has been regulated by many factors, especially fluvial runoff, sea levels, the monsoon, and oceanic circulation (Diekmann et al, 2008;Dou et al, 2010aDou et al, ,b, 2012Katayama and Watanabe, 2003;Xu et al, 2014a;Youn and Kim, 2011). Therefore, the trough is an ideal natural laboratory for studying land-sea interaction and paleoenvironmental change in the northwestern Pacific marginal seas during the late Quaternary (Tada et al, 2013).…”

“…Therefore, the trough is an ideal natural laboratory for studying land-sea interaction and paleoenvironmental change in the northwestern Pacific marginal seas during the late Quaternary (Tada et al, 2013). In this respect, the Okinawa Trough has attracted interest regarding its sediment provenance, formation age, and evolution since the last glaciation in response to the aforementioned factors (e.g., Diekmann et al, 2008;Dou et al, 2012;Li et al, 2014;Meng et al, 2009;Xiang et al, 2007;Xu et al, 2014a;Zheng et al, 2011Zheng et al, , 2014.…”

“…Previous studies on rare earth elements and clay minerals in core PC-1 taken from the northern Okinawa Trough (Xu et al, 2012a(Xu et al, , 2014a were limited due to the susceptibility of previous indices (e.g., clay minerals) during transport and depositional processes, relatively high analytical error of about 5% for previous analytical methods (e.g., low contents of chlorite and kaolinite in the study core with average values of 11% and 4%, respectively, that are similar to analytical error), and insufficient AMS 14 C dating. Sr-Nd isotopic compositions of detrital fractions, concentrations of detrital provenance-indicative elements, together with AMS 14 C ages of some key layers, of the core were acquired.…”

We present a new high-resolution multiproxy data set of Sr-Nd isotopes, rare earth element, soluble iron, and total organic carbon data from International Marine Global Change Study Core MD06-3047 located in the western Philippine Sea. We integrate our new data with published clay mineralogy, rare earth element chemistry, thermocline depth, and d 13 C differences between benthic and planktonic foraminifera, in order to quantitatively constrain Asian dust input to the basin. We explore the relationship between Philippine Sea and high-latitude Pacific eolian fluxes, as well as its significance for marine productivity and atmospheric CO 2 during the mid-late Quaternary. Three different indices indicate that Asian dust contributes between $15% and $50% to the detrital fraction of the sediments. Eolian dust flux in Core MD06-3047 is similar to that in the polar southern Pacific sediment. Coherent changes for most dust flux maximum/minimum indicate that dust generation in interhemispheric source areas might have a common response to climatic variation over the mid-late Quaternary. Furthermore, we note relatively good coherence between Asian dust input, soluble iron concentration, local marine productivity, and even global atmospheric CO 2 concentration over the entire study interval. This suggests that dust-borne iron fertilization of marine phytoplankton might have been a periodic process operating at glacial/interglacial time scales over the past 700 ka. We suggest that strengthening of the biological pump in the Philippine Sea, and elsewhere in the tropical western Pacific during the mid-late Quaternary glacial periods may contribute to the lowering of atmospheric CO 2 concentrations during ice ages.

High‐resolution multiproxy records, including clay minerals and Sr‐Nd‐Pb isotopes of the clay‐sized silicate fraction of sediments from IODP Site U1429 in the northern Okinawa Trough, provide reliable evidence for distinct control mechanism on fine‐grained sediments input from the Yellow River and the southern Japanese Islands to the northern Okinawa Trough since 34 ka BP. Provenance analysis indicates that the sediments were mainly derived from the Yellow River and the island of Kyushu. Since the last glacial, clay‐sized sediments transported from the Yellow River to the study site were strongly influenced by sea‐level fluctuation. During low sea‐level stage (∼34–14 ka BP), the paleo‐Yellow River mouth was positioned closer to the northern Okinawa Trough, favoring large fluvial discharge or even direct input of detrital sediments, which resulted about four times more flux of clay‐sized sediments supply to the study area as during the relatively high sea‐level stage (∼14–0 ka BP). The input of Kyushu‐derived clay‐sized sediments to the study site was mainly controlled by the Kuroshio Current and Tsushima Warm Current intensity, with increased input in phase with weakened Kuroshio Current/Tsushima Warm Current. Our study suggests that the Kuroshio Current was very likely flowed into the Okinawa Trough and thus influenced the fine‐grained sediment transport in the area throughout the last glacial and deglacial. During ∼34–11 ka BP, the Kyushu clay‐sized sediment input was mainly controlled by the Kuroshio Current. Since ∼11 ka BP, the occurrence of Tsushima Warm Current became important in influencing the Kyushu fine‐grained sediment input to the northern Okinawa Trough.
