“…Such deposits occur owing to the convergence of fine-particle sediments in weak current region (Zhu, 2001) and the front-induced restriction on coastal sediment dispersal (Zang et al, 2017). For instance, the presence of multisource central YS mud contradicts the shielding effect of fronts on coastal sediments (Lim et al, 2007(Lim et al, , 2015Yang et al, 2003). Such simplification is convenient for understanding the circulation patterns and sediment distributions; however, it can lead to difficulty in understanding the provenance of mud deposits.…”

“…Most previous studies have regarded the YSWC as static in controlling sediment transport and neglected its short-term change Pang et al, 2016;Gao et al, 2016).

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.

To understand the transport pathways of muddy sediment of the Kunsan basin in Yellow Sea, grain sizes and clay mineral of 32 surface sediments and a sediment core were analyzed. In the study area, illite is predominant (63.4~71.9%), followed by chlorite (15.1~20.2%), kaolinite (10.3~17.2%) and smectite (2~6.9%), According to the spatial distribution of the clay minerals, illite, kaolinite+chlorite and smectite show relatively higher contents in the center of the north, northeast, and the south of the study area, respectively. Considering the spatial distribution of clay mineral contents the sand ridge alignments and tidal current pathways, the smectite particles were probably derived from the south of the study area, but kaolinite and/or chlorite particles were mainly transported from the Korean coastal zone. Meanwhile, down-core variation in the contents of clay minerals of the core revealed a distinct change in fine-grained muddy sediment provenance: muddy sediment input from the Korean coastal areas has increased while the input from China has decreased since the last 5,000 year ago, by showing the amount decrease of smectite and the increase of kaolinite+chlorite at the top layer of the late Holocene muddy sediment unit of the core.

Quantitative reconstruction of Holocene sediment sources contributing to the central Jiangsu coast, China: New insights into source‐to‐sink processes

Coastal deltaic deposits are the primary locations for sediment storage on Earth, and quantifying their source contributions is a critical prerequisite for delineating S2S patterns in marginal seas. In most cases, quantification for the contribution by fine‐grained sediments (i.e. particle size < 63 μm) is considered to be representative to constrain the overall sediment supply. However, this approach may be inappropriate because large differences exist between the two quantities. Here we propose an approach to solve the problem, which is based on the maximum number of tracers from multiple sediment size fractions incorporating the content of all size fractions of sediment. Using this approach, absolute source contributions during the Holocene are reconstructed that provide a first‐order model for the S2S pattern of the central Jiangsu coast, China. The Huanghe River is the strongest driver for the Holocene sedimentation, with a mean contribution of ~72 ± 6% (1417 × 108 t). The absolute contributions from the Changjiang and offshore areas were of secondary importance, (i.e. ~17 ± 1% (330 × 108 t) and ~11 ± 5% (217 × 108 t), respectively). The results show that a large difference between the relative and absolute source contributions and the assumption that the relative contribution represents the absolute contribution is invalid in a coastal setting. The impact of the Huanghe is mainly based on episodic events, such as the event of 1128–1855 AD. The model also reveals that the offshore sediments are as important as the Changjiang sediments for the central Jiangsu coast during the Holocene. Thus, the model provides both the time series and overall quantities of sediment supply during the formation and evolution of the Holocene tidal flats on the Jiangsu coast. Our findings shed new light on quantitative analysis of sediment sources applicable to future S2S studies of marginal seas. © 2020 John Wiley & Sons, Ltd.
