| On the basis of bathymetric and seismic data and data from piston cores collected by the Chinese-French marine geology and geophysics investigation of 1996, we discuss the internal architecture and mobility of tidal sand ridges in the East China Sea (ECS). We characterized the sand ridges on the middle to outer shelf of the ECS as tide-dominated sand ridges with southwest dipping beds, indicating that the regional net sediment transport is toward the southwest. As the sand ridges gradually migrate toward the southwest, new sand ridges are continually replacing old ones, and several generations of sand ridges have developed in the study area. High-resolution seismic data, acoustic Doppler current profiler data, and two C-14-dated piston cores, DGKS9614... |

| This multidisciplinary case study of two preserved barrier systems combined the analysis of radiocarbon datings, grain-size distributions, high-resolution seismics, and shelf bathymetry with reconstructions of palaeo-environmental conditions (tides, waves, sea-level change) and forward modelling of barrier-lagoon systems, to provide an integrated view of the coastal transgressive evolution of a large sector of the northern Adriatic shelf between 15 and 8 ka BR Palaeo-environmental reconstructions point to increased tidal amplitude, low-energy wave climate and high rates of sea-level rise (up to 60 mm/a) during the formation of the oldest preserved barrier system (similar to 90 m water depth; 14.3 cal ka BP). A younger barrier system (42 m water depth; 10.5... |

| Isotopic, mineralogical and elemental analyses have been conducted for the geochemical characteristics of the bulk carbonates in the sediment cores from the Western High and Çınarcık Basin in the Sea of Marmara to investigate the authigenic, biogenic and detrital components and their possible use in paleoceanographic studies. The Western High is a relatively shallow (‐500 to ‐800 m) compressional area characterized by relatively low sedimentation rates (30‐40 cm/kyr) whereas the Çnarcık Basin is a deep (~1250 m) transtentional area represented by high sedimentation rates (>1 m/kyr). Both 87Sr/86Sr and δ18O of bulk carbonates from the Western High exhibit significant variations, increasing steeply from 87Sr/86Sr of 0.708437 to 0.708916 and δ18O of ‐3.2‰... |
