“…The higher the eigenvalue of an eigenmode is, the more co-variability among parameters this mode explains. In this study, salinity and temperature measured at each cast were regarded as the river plume variables to determine water column variability caused by the interplay between plume hydrodynamics and physical processes 21 , 23 , 24 .…”

Fundamentally, river plume dynamics are controlled by the buoyancy due to river effluent and mixing induced by local forcing such as winds and tides. Rarely the influence of far-field internal waves on the river plume dynamics is documented. Our 5-day fix-point measurements and underway acoustic profiling identified hydrodynamic processes on the dispersal pathway of the Pearl River plume. The river plume dispersal was driven by the SW monsoon winds that induced the intrusion of cold water near the bottom. The river effluent occupied the surface water, creating strong stratification and showing on-offshore variability due to tidal fluctuations. However, intermittent disruptions weakened stratification due to wind mixing and perturbations by nonlinear internal waves (NIWs) from the northern South China Sea (NSCS). During events of NIW encounter, significant drawdowns of the river plume up to 20 m occurred. The EOF deciphers and ranks the contributions of abovementioned processes: (1) the stratification/mixing coupled by wind-driven plume water and NIWs disruptions (81.7%); (2) the variation caused by tidal modulation (6.9%); and (3) the cold water intrusion induced by summer monsoon winds (5.1%). Our findings further improve the understanding of the Pearl River plume dynamics influenced by the NIWs from the NSCS.

“…In summer, large river discharges and strong southwesterly winds allow the ZJR effluent to enter the TS (Bai et al, 2015). In addition, river effluents along the TS also deliver large amount of terrestrial material into the strait (Liu et al, 2019). Liu et al (2019) described TS as a monsoon-driven artery that intermittently pump nutrient-rich water that carries terrestrial-sourced material to the ECS in summer.…”

Previous studies also pointed out a major conduit to transport the CJRderived terrestrial material from ECS into SCS along the coast of Mainland China (Xu et al, 2009;Liu et al, 2010Liu et al, , 2014Liu et al, , 2018Hu et al, 2012).…”

The Taiwan Strait is a conduit between East China Sea (ECS) and South China Sea (SCS). Seasonal monsoon winds drive the southbound Zhejiang-Fujian Coastal Current and northbound SCS Warm Current through the strait. Water masses carried by these major current systems also carry fluvial signals from two major rivers, the Changjiang (Yangtze) River in ECS and the Zhujiang (Pearl) River in SCS through the strait. Here we show a switch occurred to signify the monsoon regime change on the western side of this conduit around 10:00 on May 8, 2015. Our data came from water mass properties and environmental proxies of N/P ratio in the surface water and 7Be and 210Pbex isotopes in surface sediments. The timings of the demarcation were identical in the water column and on the water-sediment interface. Our findings put a specific time point in the monsoon regime change in 2015.

“…The interactions among the different water masses can be delineated by mapping sea-surface temperature fronts from satellite images (Liu et al, 2019). The near-surface current reversals between different seasons can be monitored by High-Frequency Ground Wave Radar system (Zhu et al, 2008).…”
