“…According to the spatial distribution of ∑REEs, it was clear that Yalu River sediment dominated the eastern part of the study area and its influence gradually decreased to the west. Other potential sources that could be transported to LNCM were analyzed in the supporting information via various proxies, for example, trace elements (Ti, Sr, and Rb; Yang et al, 2003;Zhao et al, 1990), and the result showed that the Yellow River was the major contributor to LNCM.…”

The geochemical analysis of sediment in the northern North Yellow Sea shows that the sediment derived from the Yellow River could penetrate the Yellow Sea Warm Current and mingle with Yalu River‐derived sediment in coastal areas. Further analysis indicates that the relative variations in coastal currents and the Yellow Sea Warm Current, which are regulated by the winter monsoon, dominate the process of cross‐front transport. This suggests a dynamic mechanism involving cross‐front sediment transport. During a period of strong northwesterly wind, the sediment derived from the Yellow River north of the Shandong Peninsula could disperse across the fronts in the surface layer, and when the wind subsides, sediments are delivered northward by barotropic current. This dynamic mechanism for sediment exchange in the North Yellow Sea can explain the multiple sediment sources found in the Yellow Sea, and it has implications for cross‐front transport on a global scale.

Acronyms are defined as follows: 1 and determined that the CYSM was formed from a complex mixture of sediments from the Huanghe, as well as the Changjiang and several Korean rivers (Zhao et al, 1990;Wei et al, 2003;Zhang et al, 2008;Li et al, 2014a;Wang et al, 2014;Koo et al, 2018). In addition, recent studies using core sediments suggested that the provenance of CYSM changed mainly from Huanghe to Changjiang with a minor contribution from the Korean rivers during the Holocene (Lim et al, 2015;Hu et al, 2018).…”

Abstract. The sediment supply to the central Yellow Sea since the last deglaciation was uncovered through clay mineralogy and geochemical analysis of core 11YS-PCL14 in the Central Yellow Sea Mud (CYSM). The core can be divided into four units based on the various proxies, such as grain size, clay mineralogy, geochemistry, and Sr and Nd isotopes: Unit 4 (700–520 cm; 15.5–14.8 ka), Unit 3 (520–310 cm; 14.8–12.8 ka), Unit 2 (310–130 cm; 12.8–8.8 ka), and Unit 1 (130–0 cm; <8.8 ka). Unit 2 is subdivided into two subunits, Unit 2-2 (310–210 cm; 12.8–10.5 ka) and Unit 2-1 (210–130 cm; 10.5–8.8 ka), according to smectite content. Comparison of the clay mineral compositions, rare earth elements, and εNd indicate distinct provenance shifts in core 11YS-PCL14. Moreover, the integration of clay mineralogical and geochemical indices show different origins according to particle size. During the late last deglaciation (Units 3 and 4, 15.5–12.8 ka), Unit 4 sediments originated from all potential provenance rivers, such as the Huanghe, Changjiang, and western Korean rivers, while the source of coarse sediments changed to the Huanghe beginning with Unit 3. Fine-grained sediment was still supplied from all rivers during the deposition of Unit 3. Early Holocene (Unit 2) sediments were characterized by oscillating grain size, clay minerals, and moderate εNd values. In this period, the dominant fine-sediment provenance changed from the Huanghe to the Changjiang, whereas coarse sediments most likely originated from western Korean rivers. The Unit 1 CYSM sediments were sourced primarily from the Changjiang, along with minor contributions from the western Korean rivers. Possible transport mechanisms concerning such changes in the sediment provenance include paleo-river pathways, tidal stress evolution, and the development of the Yellow Sea Warm Current and coastal circulation systems, depending on the sea level fluctuations.

“…On the other hand, other studies have used mineralogical, geochemical, and magnetic observations and determined that the CYSM was formed from a complex mixture of sediments from the Huanghe as well as the Changjiang and several Korean rivers (Zhao et al, 1990;Wei et al, 2003;Zhang et al, 2008;Li et al, 2014a;Wang et al, 2014;Koo et al, 2018). In addition, 40 recent studies using core sediments suggested that the provenance of CYSM changed mainly from Huanghe to Changjiang with minor contribution from the Korean rivers during the Holocene (Lim et al, 2015;Hu et al, 2018).…”

Abstract. The sediment supply to the central Yellow Sea since the Last Glacial Maximum was uncovered through clay mineralogy and geochemical analysis of core 11YS-PCL14 in the Central Yellow Sea mud (CYSM). The core can be divided into four units: Unit 4 (700–520 cm; 15.5–14.8 ka), Unit 3 (520–280 cm; 14.8–12.1 ka), Unit 2 (280–130 cm; 12.1–8.8 ka), and Unit 1 (130–0 cm;
