Data from the Yangtze River. a Satellite image showing the Yangtze River plunging into the East China Sea. Note development of both hyperpycnal plume (yellow color due to high sediment concentration) near the river mouth and hypopycnal plume (blue color due to low sediment concentration) on the seaward side. Note deflected hypopycnal flows that move southward (white arrow), possibly due to modulation by south-flowing shelf currents. In a recent study, Luo et al. (2017) recognized that extended and deflected density plumes (white arrow) tend to develop during winter months, which are absent during the summer months. Note sheet-like mud belt developed along the inner shelf due to contour-following shelf currents. White dashed circle = River mouth. See Fig. 12a for the river course; see also Fig. 7a.
