Special Issue Information

Dear Colleagues,

The ocean accounts for more than 71% of the Earth's surface, and particulate matter from the outer planets, the interior of the earth, the land, and the ocean itself is aggregated and deposited in the ocean basin. The development of observation technology is crucial for understanding both the transport dynamics and deposition process of particles under different marine environments. There are a wide variety of observation techniques for observing the marine sedimentary dynamic environment, the sedimentary process of a particle, sedimentary structure of a seabed, and sediment distribution. The observation methods include the earth observation system, shipborne observation, in situ observation, manned submersible observation, and unmanned submersible observation. With human beings becoming increasingly dependent on marine resources, the environment, and world peace, a variety of new marine observation techniques are constantly emerging, promoting the development of the marine sedimentary dynamic environment and marine sedimentology.

The purpose of this Special Issue is to present the latest progress in the application of marine observation techniques to marine sedimentary dynamics and marine sedimentology. We welcome contributions in all areas of marine sedimentological observation and based on various sensors, such as acoustics, visible spectrum, laser, radar, SAR, electricity, thermodynamics, sonar, seism, and so on. These include, but are not limited to, the following:

  • Remote sensing;
  • Observation of sedimentary dynamic environment;
  • Observation of suspended particle concentration;
  • Identification of submarine sediment types;
  • Exploration of seafloor sedimentary strata;
  • Data interpretation model.

Due to the regional differences between the North and South Yellow Sea, and under the influence of winter winds, the relative changes in the coastal current and the Yellow Sea warm current will lead to the instability of the front, which will lead to the cross-front transport of sediment. Therefore, the study of sediment exchange between the North and South Yellow Sea has become an indispensable part of the study of the Yellow Sea environment. In this study, the current field and sediment concentration in the southern part of Chengshantou, a representative area of the Yellow Sea, were observed in winter in order to analyze the sediment exchange process between the North Yellow Sea and the South Yellow Sea in winter. The observation results show that in the southern sea area of Chengshantou, in winter, the current velocity does not change with the water depth when it exceeds 15 m, and the tides are regular semi-diurnal tides. When the water depth is less than 15 m, the current direction changes clockwise with the increase in the water depth. The turbidity increases rapidly when the wind direction is offshore and the bottom residual current is onshore, which may cause the sediment transported offshore under the action of wind and ocean current to settle under the obstruction of the Yellow Sea warm current, resulting in the rise of bottom turbidity. This also indicates that the change in residual current direction at different water depths may also lead to an increase in suspended sediment concentration. Based on this, in the estuarine area, the relative change in the current direction between the wind current and the coastal current may also be the cause of the change in the maximum turbidity zone.
