Summary: This study investigates the components, concentrations, distribution characteristics, and sources of low-molecular-weight organic acids (LMWOAs) in the Changjiang Estuary and its adjacent sea area. The results show that terrigenous inputs, especially the Changjiang runoff, are the dominant sources of LMWOAs. The consistency between hypoxia areas, high concentration areas of LMWOAs, and low pH value areas suggests that annual hypoxia could cause long-term seawater acidification by producing LMWOAs.

Summary: The study found that the formation and maintenance of low oxygen offshore of the Changjiang River Estuary occur at high frequencies in certain regions known as bottom hypoxia hotspots, specifically the southern shallow bank and submarine canyon. The spatial extent of bottom hypoxia is significantly sensitive to riverine inputs, particularly changes in river discharge, which have a greater impact on hypoxia over the shallow bank than the submarine canyon. Increasing wind speed can reduce the spatial extent and total volume of bottom hypoxic water, while weakening Kuroshio intrusion can prolong the near-bottom water residence time and increase bottom hypoxia extent.

Summary: Recent evidence has revealed active N-2 fixation in coastal eutrophic waters, particularly in large estuaries like the Changjiang Estuary (CE). The size-fractionated N-2 fixation rates (NFRs) were directly measured off the CE during summer 2014, showing significant spatial variations and different contributors (Trichodesmium and heterotrophic diazotrophs). The distribution and size structure of N-2 fixation were found to be regulated by water mass movement and associated diazotrophs, as well as nutrient conditions.

Summary: In recent years, the occurrence of hypoxia in the East China Sea has increased due to intensified human activities and the threat from Kuroshio. This study investigated the different contributions of Changjiang and Kuroshio to oxygen depletion over the continental shelf, specifically focusing on the Zhejiang Coast. The results showed that Changjiang diluted water primarily constrained intense oxygen depletion and bottom hypoxia in the northern region, while upwelled materials associated with Kuroshio subsurface water enhanced oxygen depletion in the southern region. The study also found that upwelling supported surface phytoplankton bloom along the Zhejiang Coast and fertilized phytoplankton growth at the subsurface.

Summary: The study investigated the use patterns of salt marsh habitats by fish assemblages in two well-developed intertidal creeks in the Changjiang (Yangtze) River estuary. The results showed notable changes in fish assemblages over seasonal and interannual cycles. The appearance of catadromous species in intertidal creeks mainly depended upon their specific physiological requirements. No significant diel shifts were observed in fish assemblages. The spatial difference in fish community was insignificant even though the two intertidal creeks were different in size.

Summary: Wind mixing plays a crucial role in regulating variations in dissolved oxygen (DO), but there is limited field data on how DO dynamics respond to wind disturbance. Observations off the Changjiang Estuary during a fresh wind event in 2017 revealed that physical mixing and biological activity contribute to DO variations. While the wind event alleviated hypoxia in the water column, it exacerbated poorly ventilated near-bottom hypoxia. The air-sea exchange of DO, especially in nearshore areas, is important for offsetting the DO deficiency caused by wind-induced mixing.

Summary: This study investigated the seasonal source and contributions of internal decomposition of organic matter (OM) in the Kuroshio Subsurface Water (KSSW) for hypoxia formation in the East China Sea (ECS). The results showed that in June, N-2 fixation signals related to decomposed OM were apparent in the southern ECS, while terrestrial input signals were revealed in the northern ECS and most of the ECS in October. The terrestrial input contributed almost equally to the development of ECS hypoxia as compared to marine sources, indicating the importance of understanding eutrophication and oceanic circulation in hypoxia formation.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.
