“…Then, the paleo-shoreline was positioned in the far south or southeast of Jeju Island and the continental shelf of the present study area was entirely exposed, resulting in subaerial erosion associated with fluvial incision (Fig. 12, Lee and Yoon, 1997;Liu et al, 2004;Park et al, 2006;Shinn et al, 2007;Yang et al, 2014). An incised valley was cut across the shelf by the paleo-Huanghe and Korean Rivers.…”

“…The olive gray colored sedimentary unit is highly bioturbated. Muddy sand with high degree of bioturbation and low water content is also observed (Lee and Yoon, 1997;Shinn et al, 2007). Shells from the cores retrieved from SU2 were dated between 19,657 ± 275 cal a BP, 18,311 ± 184 cal a BP, and 18,041 ± 153 cal a BP, respectively (Fig.…”

“…Additionally, the large tidal range and strong tidal currents of the region produce a complex and dynamic hydraulic regime in terms of sediment erosion and deposition (Alexander et al, 1991;Park et al, 2000;Lee and Chu, 2001;Lee et al, 2014). Late Quaternary sedimentary units may have been created and remain in the modern Yellow Sea (Yang and Sun, 1988;Alexander et al, 1991;Lee and Yoon, 1997;Jin and Chough, 1998;Park et al, 2000;Liu et al, 2004;Kong et al, 2006;Shinn et al, 2007;Lee et al, 2014Lee et al, , 2015. Such deposits are well recorded on the seafloor and bear witness to the complex interplay between depositional and erosional processes, which are closely related to sealevel changes.…”

“…A sufficient supply of material is advantageous for the formation of accumulating sand ridges, e.g., the continental shelf of the ECS (Berné et al 2002). Poor material supply or strong dynamics may possibly lead to the formation of eroded sand ridges, e.g., offshore of the Korean peninsula (Jin andChough 1998, 2002;Jung et al 1998;Park et al 2000Park et al , 2003Shinn et al 2007;Yoo et al 2005). Three stages of infancy, growth, and maturation could be experienced during the development of accumulating sand ridges (Snedden and Dalrymple 1999).…”

Based on multi-beam echo soundings and highresolution single-channel seismic profiles, linear sand ridges in U14 and U2 on the East China Sea (ECS) shelf are identified and compared in detail. Linear sand ridges in U14 are buried sand ridges, which are 90 m below the seafloor. It is presumed that these buried sand ridges belong to the transgressive systems tract (TST) formed 320-200 ka ago and that their top interface is the maximal flooding surface (MFS). Linear sand ridges in U2 are regressive sand ridges. It is presumed that these buried sand ridges belong to the TST of the last glacial maximum (LGM) and that their top interface is the MFS of the LGM. Four sub-stage sand ridges of U2 are discerned from the high-resolution single-channel seismic profile and four strikes of regressive sand ridges are distinguished from the submarine topographic map based on the multi-beam echo soundings. These multi-stage and multi-strike linear sand ridges are the response of, and evidence for, the evolution of submarine topography with respect to sea-level fluctuations since the LGM. Although the difference in the age of formation between U14 and U2 is 200 ka and their sequences are 90 m apart, the general strikes of the sand ridges are similar. This indicates that the basic configuration of tidal waves on the ECS shelf has been stable for the last 200 ka. A basic evolutionary model of the strata of the ECS shelf is proposed, in which sea-level change is the controlling factor. During the sea-level change of about 100 ka, five to six strata are developed and the sand ridges develop in the TST. A similar story of the evolution of paleotopography on the ECS shelf has been repeated during the last 300 ka.

“…In most cases, sand banks and ridges have been reported in environments clearly dominated by a single hydrodynamic agent, either uni-directional storm-driven currents in North American shelves (Amos and King, 1984;Dyer and Huntley, 1999;Snedden and Dalrymple, 1999) or reciprocal tidal currents in the North Sea (Berné et al, 1994;Dyer and Huntley, 1999;Trentesaux et al, 1999) and in the Eastern China and Yellow Seas (Park et al, 2006;Liu et al, 2007;Shinn et al, 2007). These hydrodynamic agents dominate the net bedload transport and hence control the migration trends of large-scale sediment bodies.…”

A previously unknown fi eld of large-scale sedimentary bodies has been mapped and studied on the continental shelf off the Cape Trafalgar near the Strait of Gibraltar with particular emphasis on the relationship between large-scale sediment bodies and the superimposed bedforms. This study is based on a grid of 975 km of high-resolution seismic profi les collected at water depths ranging between 15 and 60 m.High variability of large-scale sedimentary bodies is attributed to the complex interaction of hydrodynamic agents. The most prominent sedimentary features are sand banks and ridges that indicate long-term southwest and southward-directed sediment transport patterns, possibly due to the interplay of two dominant current systems fl owing southward and westward. These sediment bodies evolve laterally to distinct external geometries, such as sand shoals in shallow water and sand sheets in the vicinity of larger sand banks that indicate moderate current velocities. In addition, pre-existing physiography is considered to play a role in the generation of certain sediment bodies, developed over inclined surfaces or confi ned laterally by elevations.Relationships between superimposed bedforms (mostly very large dunes) and underlying sediment bodies vary across the study area. Most superimposed bedforms occur over the complex mosaic of sediment banks and sheets, suggesting the interaction of several high-energy currents with different directions, such as tidal and/or wind-driven currents.
