“…Moreover, developing renewable energy helps reduce greenhouse gas emissions, mitigate the impact of climate change, and contribute to global environmental protection. Apart from the development of renewable energy, it's also important to pay attention to energy storage and transmission issues [5]. As renewable energy is used on a large scale, effectively storing and transmitting it becomes a crucial problem.…”

Plankton, as a crucial component of aquatic ecosystems, plays a key role in maintaining ecological balance with its population and diversity. However, with the increase in human activities, the emission of nuclear waste, and the frequency of nuclear accidents, the issue of nuclear pollution has become increasingly severe, posing a significant threat to the living environment of plankton. The primary sources of nuclear pollution are the discharge of nuclear waste and leaks from nuclear power plant accidents. These radioactive substances dissolve in water and emit radiation, causing severe damage to the aquatic ecosystem. Plankton, such as algae and protozoa, due to their characteristics, are more susceptible to radiation. The impact of nuclear pollution on the population and diversity of plankton is evident. To protect the balance of aquatic ecosystems, it's necessary to strengthen the management and regulation of nuclear pollution, reduce the discharge of nuclear waste, and lower the risk of nuclear accidents. Also, for water bodies already affected by nuclear pollution, effective purification measures should be taken to restore the health of the aquatic ecosystem.

“…The complex dynamic physical characteristics of the CRE drive the biochemical cycles of nutrients, suspended matter, and light, ultimately affecting the spatial and temporal distribution and physiological status of phytoplankton in the estuary and its adjacent sea areas (Li et al, 2021). There are many records of the temporal and spatial dynamics of the phytoplankton in the CRE (e.g., Wang et al, 2021;Fang et al, 2022;Gao et al, 2022). However, there has been a lack of in situ data sets about the photosynthetic characteristics of phytoplankton in the mixing of different water masses of this estuarine area.…”

IntroductionThe Changjiang (Yangtze) River is one of the largest rivers in the world, and its estuary and offshore plume create a diversity of ecological habitats for the phytoplankton community. The phytoplankton community has to balance between light limitation in the sediment-laden inshore waters and nutrient limitation in the offshore waters. Active fluorescence measurements can provide rapid, non-intrusive estimates of photosynthetic characteristics at high spatial and temporal resolution.MethodsIn the summer of 2020, a field survey of hydrodynamic characteristics, availability of nutrients, the maximum quantum efficiency of photosystem II (Fv/Fm), and rapid light curves across the Changjiang River Estuary and its adjacent sea was conducted, assessing relationships between photosynthetic physiology and biomass accumulation.ResultsThe photosynthetic activities significantly differed among the turbid river water, the stratified river plume water, and the oceanic East China Sea Water. The photosynthetic physiology of phytoplankton was the most active near the front of Changjiang Diluted Water, where the Fv/Fm was over 0.5.DiscussionPhytoplankton photosynthesis was alleviated from light limitation downstream of the river mouth, and benefited from phosphorus supply via tidal mixing and upwelling. The relatively suitable light and nutrients led to high photosynthetic activities, supporting increased productivity and biomass in this water. The phytoplankton in the Changjiang estuary rivermouth were under intense stress, suggested by the Fv/Fm values under 0.3. Also, the strong vertical mixing process diluted the river nutrients before the phytoplankton consumed them. Nutrients further limited the phytoplankton offshore in the East China Sea.

“…Long-term studies conducted in coastal East China Sea, using extensive datasets, have revealed a decrease in diatom abundance and an increase in dinoflagellate abundance in response to higher temperatures and eutrophication. This suggests that diatoms and dinoflagellates exhibit distinct responses to warming and eutrophication (Chen et al, 2017;Xiao et al, 2018;Gao et al, 2022).…”

“…Consequently, this method leads to an underestimation of depth-averaged phytoplankton abundance by one to two orders of magnitude when compared to the water collection method (Jiang et al, 2020). Notably, certain investigations employing the water collection method have revealed significant heterogeneity in community composition across three distinct subregions within Sanmen Bay (Gao et al, 2022). Typically, Sanmen Bay is characterized as a partially enclosed harbor with an exposed entrance adjacent to the East China Sea.…”

“…Typically, Sanmen Bay is characterized as a partially enclosed harbor with an exposed entrance adjacent to the East China Sea. The bay's ecological dynamics are primarily influenced by the confluence of riverine influxes, the Zhemin Coastal Current, and the Taiwan Warm Current (Zhu et al, 2012), potentially impacting the diversity and intricacy of phytoplankton composition (Xie et al, 2015;Chen et al, 2017;Jiang et al, 2020;Gao et al, 2022). Consequently, the phytoplankton composition in the bay consists of both freshwater or brackish species originating from tributaries, such as Pediastrum simplex, Phormidium tenesmue, and Melosira granulata v. austissima.…”

In the context of global change, the stressors of warming and eutrophication have significant ecological implications in coastal waters. In order to examine the diversity of phytoplankton and its relationship with water quality, we conducted a survey of phytoplankton community compositions and their correlation with environmental changes over four seasons in a eutrophic bay located in the East China Sea. Through a systematic analysis, we identified diatoms and dinoflagellates as the primary dominant groups, with the species Skeletonema costatum, Skeletonema marinoi, Biddulphia sinensis, Thalassiosira eccentrica, Leptocylindrus danicus, Coscinodiscus oculus-iridis, Coscinodiscus jonesianus, and Chaetoceros knipowitschi as the most abundant species in all seasons. Significant seasonal alterations were observed in both environmental settings and phytoplankton species richness, dominance, and abundance. The phytoplankton community varied in its response to diverse aquatic environments and was principally affected by temperature, silicic acid concentrations, and suspended solids. Elevated temperatures were found to promote an increase in phytoplankton abundance. However, no clear evidence of diatom and dinoflagellate succession in relation to N:P ratio was observed across seasons. Water quality analysis illustrated that the majority of the study area exhibited a mid-eutrophic with severe organic pollution. The abundance of phytoplankton was significantly influenced by eutrophication and organic pollution. The accelerated warming process related to coastal nuclear power plants and nutrient regime alterations significantly affect the temporal shift of the phytoplankton community. These findings contribute valuable insights into the effects of eutrophic environments on the structure of phytoplankton communities in coastal aquatic systems.
