Summary: This study measured turbidity, TSS, CHLa, DOC, and CDOM in upper segments of estuaries to better understand their role in light attenuation. Turbidity and TSS were found to be the best predictors of light attenuation, while CHLa was not a strong predictor. CDOM played a significant role in some sub-estuaries, and external inputs did not strongly predict estuarine light attenuation.

Summary: Rapid population growth globally is the main cause of deteriorating water quality in urbanized estuaries. The temporarily closed Hartenbos Estuary in South Africa, impacted by wastewater treatment plant discharges, experiences frequent artificial breaching to prevent flooding and extreme events. The ecosystem in the estuary is characterized by high nutrient loads, hypereutrophic conditions, and dominance of a few opportunistic species tolerant of adverse conditions. Management priorities for improving the health and biodiversity of such systems include diverting wastewater treatment plant discharges and restoring hydrodynamic variability.

Summary: Estuarine primary production (PP) is a critical rate process for understanding ecosystem function and response to environmental change, but it can be influenced by various factors such as nutrient management, warming, altered hydrology, and harmful algal blooms. The increase in PP in the York River Estuary is associated with higher water temperature, decreased turbidity, and increased light availability, indicating phytoplankton have become more efficient at converting nutrients into biomass.

Summary: Extensive multi-species harmful algal blooms (HABs) were triggered by Super Typhoon Lekima in Laizhou Bay. After the typhoon, the abundance of phytoplankton and Chl a concentration significantly increased. The study suggests that typhoons may introduce freshwater and nutrients, leading to changes in the phytoplankton community and HABs in temperate inner bays.

Summary: The study reveals that the toxic substances produced by toxic phytoplankton suppress the grazing population, giving both phytoplankton species an advantage and leading to irregular patterns in their seasonal growth. The dynamics of toxic phytoplankton blooms become more irregular and severe in the presence of high toxic effects, while non-toxic phytoplankton show annual blooms.

Summary: Bed stress patterns control erosion and deposition in tidal rivers. The variability of bed stress profiles and its impact on sediment transport were investigated in this study. The analytical formulation developed herein will contribute to the understanding of long-term erosion/accretion patterns and guide future investments for managing sediment in rivers affected by climate change and human activities.

Summary: Harmful algal blooms, especially cyanobacterial blooms, are occurring in many freshwater lakes worldwide, impacting public health and ecosystem integrity. To mitigate their negative effects, prediction, early detection, and monitoring of algal blooms are crucial. Remote sensing, including different platforms and AI-based algorithms, provides an effective and cost-efficient method for detecting and monitoring these events. Recent advancements in using UAV platforms equipped with sophisticated sensors have revolutionized the detection and monitoring of water quality. Predicting algal blooms based on AI methods will play a key role in mitigating eutrophication in the future.

Summary: Qinzhou Bay in Guangxi coastal area is a hot spot for harmful algal blooms, especially of the species Phaeocystis globosa. A six-month continuous survey revealed that the phytoplankton community structure varied with time, with P. globosa being the dominant species. Factors such as hydrology and chemistry, including phosphorus limitation, had a significant impact on the community structure and diversity.

Summary: Marine microalgae produce toxic metabolites that harm humans, farmed fish, and marine wildlife, accumulating in shellfish and higher trophic organisms. Molecular methods, particularly qPCR, have become popular for monitoring harmful microalgae, with focus on toxin gene monitoring technologies for early detection and prevention of harmful algal blooms.

Summary: Harmful algal blooms caused by Heterocapsa bohaiensis have been occurring in aquaculture areas near Liaodong Bay, China since 2012, resulting in mass mortality of Eriocheir sinensis larvae and significant economic loss. This study investigated the interspecific competition between H. bohaiensis and Chlorella pyrenoidosa to understand why H. bohaiensis dominates the phytoplankton community. The results showed that H. bohaiensis achieved competitive advantage through exploitation competition, rather than allelopathy.

Summary: Estuaries in rainfall poor regions like Coorong, Australia, are facing ecological health decline due to reduced freshwater inflows and increased evapo-concentration. The persistently hyper-saline and hypereutrophic conditions in Coorong are affecting water quality and sediment quality, leading to negative impacts on the ecosystem. Increasing lagoonal flushing would help to reduce hypersalinisation and hypereutrophication and improve the health of the ecosystem.

Summary: This study investigates the effects of climate change on harmful algal blooms (HABs) in coastal China. The researchers analyze HAB observed data since 1981 and identify the key environmental drivers of HABs, such as nutrients, sea surface temperature (SST), and precipitation. The results show that HABs have expanded their geographic range and increased their impacting period in China's near seas. Rising total nitrogen (TN) or SST is found to be the dominant factor driving the increase in HABs. The study highlights the importance of controlling watershed nutrient input to mitigate marine eutrophication.

Summary: Algal blooms pose a serious threat to water resources globally, and detecting them early remains challenging in eutrophication management. A fuzzy logic-based early warning system was developed in this study, utilizing key parameters to accurately predict algae blooms in a river impacted by tidal sluices. The system successfully reproduced past algal bloom events and highlighted the importance of dissolved oxygen and velocity for early warning systems in tidal rivers in urban areas of South China.

Summary: Coastal marine ecosystems are crucial for Earth's biogeochemical and ecological functions, but are highly sensitive to the impacts of climate change and human activities. A study monitoring 12 sampling stations in 8 ecosystems in France over 2 decades found two abrupt changes in 2001 and 2005, indicating the influence of climate change on coastal ecosystems with trends towards increasing temperature and salinity, and decreasing chlorophyll a, nutrients, and particulate matter.

Summary: Coastal ecosystems receive different amounts of nutrients from the continent and human activities, and their nutrient concentrations have been changing over time. Most of the French coastal ecosystems showed a decrease in nutrient concentrations, except for the Arcachon Bay. Monitoring ecosystem changes and considering both local and large-scale factors are important for understanding and managing coastal ecosystems.
