China - Tidal Variation of Total Suspended Solids over the Yangtze Bank

The Yangtze Bank is a flat and broad shallow water, located at the junction of the Yellow Sea and the East China Sea.

Large river discharge and strong wind- and tide-induced mixing created a large amount of land sediment discharge as well as the resuspension of bottom sediment, making the Yangtze Bank one of the most turbid coastal areas in the world (Figure 1). The high resolution distribution and tidal variation of suspended sediment over the Yangtze Bank have been revealed in a recent study.

The relevant article "Tidal variation of total suspended solids over the Yangtze Bank based on the geostationary ocean color imager" was published in Science China: Earth Sciences recently, written by a group led by Daji HUANG from the second Institute of Oceanography, Ministry of Natural Resources. The world's first Geostationary Ocean Color Imager (GOCI) was used to reveal the high resolution spatial pattern and tidal variation of total suspended solids (TSS) over the Yangtze Bank in the Yellow and East China Seas during the winter.

The movement and distribution of suspended sediment are accompanied by processes such as pollutant transmission, nutrient transport, and changes in optical characteristics of seawater, which directly affect the hydrodynamic and ecological environment of seawater. Therefore, sediment transport and distribution in the sea have received attention from oceanographers. So far, scholars have conducted extensive research on suspended sediment transport in different sea areas of the world.
