The northern shelf of the South China Sea (NSSCS) is characterized by surface low-salinity water due to discharge from the Pearl River.
In such an environment, the surface sound duct (SSD) is the most important duct for near-surface sonar applications.
Nevertheless, the mechanism of SSD formation is very complicated and is influenced by salinity, temperature at the air-sea interface, and various additional marine phenomena.
In this study, an 8-year conductivity-temperature-depth (CTD) profile of the NSSCS was used to analyze the SSD formation.
An advanced diagrammatic method is proposed to provide a quantitative analysis of the contribution of salinity, temperature, and hydrostatic pressure on SSD formation.
Large salinity gradient (0.25 psu/m) was shown to play a crucial role in SSD formation when a mixed layer exists.
As representative examples, the sea under cold surges, typhoon genesis, and low-salinity lenses were studied.
Conversely, the absence of SSDs in low-salinity water was also observed in upwelling regions.
This study further showed that highly negative temperature gradients affect SSD formation even in low-salinity water.
Furthermore, although the duct depth of a low-salinity SSD is usually less than 10 meters, it still can serve as an effective duct for acoustic propagation.
