Summary: Rapid urbanization and economic development in coastal regions have led to coastal nutrient pollution and changes in phytoplankton community. This study collected high-temporal-resolution samples to investigate the influence of environmental factors on phytoplankton succession. The results showed that inflows and dissolved inorganic phosphorus significantly impact the succession of phytoplankton communities and the occurrence of algae blooms.

Summary: This study assesses the environmental conditions and develops a sub-seasonal forecast model to predict the abundance of D. acuminata cells in the Lyngen fjord. The model uses past cell concentration, sea surface temperature, Photosynthetic Active Radiation, and wind speed to predict future cell abundance.

Summary: Phytoplankton blooms play a crucial role in marine ecosystems by providing biomass, aiding carbon sequestration, and potentially posing risks when harmful species are involved. The seasonal blooms in the Barents, Norwegian, and North seas are influenced by factors such as mixed layer depth, sea surface temperature, wind speed, and suspended particulate matter. Variability in the timing and intensity of spring and summer blooms in these regions can be attributed to unique environmental conditions and oceanographic processes.

Summary: This study utilized multi-spectral and operational land imaging instruments to monitor spatial and seasonal variations in floating algae blooms in Lake Xingyun, China from 2016 to 2020. Results showed that floating algae occurred more in the northern region and were more frequent in summer and autumn seasons.

Summary: In this study, a comprehensive investigation of the occurrence, phase partitioning, spatial distribution, potential sources, and environmental influencing factors of domoic acid (DA) in the Bohai and Northern Yellow seas was conducted. The results showed that DA was predominantly found in the dissolved phase and originated mainly from the phytoplankton Pseudo-nitzschia pungens in the aquaculture zone. This study is important for understanding the prevalence of DA in these seas and suggests the need for routine monitoring to prevent contamination of shellfish farms.

Summary: Harmful algal blooms (HAB) are a recurrent and widespread issue in northern Europe, affecting aquaculture industry and socioeconomic interests. The major HAB taxa causing fish mortalities include Chrysochromulina leadbeateri, Prymnesium polylepis, Phaeocystis spp., Dinophysis spp., and Alexandrium species. Continued monitoring and understanding of these HABs is essential to prevent and mitigate their impacts.

Summary: Freshwater cyanobacterial harmful algae blooms (cHABs) pose a major threat to human and environmental health. However, the diverse genomic and metabolic characteristics of cyanobacteria make it difficult to accurately predict their responses to environmental changes. Establishing a competitive framework and considering changes in abundance of non-cyanobacterial specialist phytoplankton can provide valuable insights for managing the increasing frequency and severity of cHABs.

Summary: A data-driven approach was used to characterize the risk of cyanobacteria-based harmful algal blooms in the Ohio River. Bayesian regression models were developed using 25 years of river discharge data to predict bloom occurrence and persistence. The models provide probabilities of occurrence or persistence with uncertainty and are served in real time through a risk characterization tool/web application. The tool also includes visualization options for studying water quality trends.

Summary: Cyanobacteria are a major cause of algal bloom, and deep learning-based image processing methods can be used for the rapid identification and classification of these cyanobacteria. The proposed ensemble model outperforms classic CNNs in terms of accuracy rate and ROC curve area, with a shorter execution time.

Summary: This review article discusses the complex and dynamic interactions between bacteria and phytoplankton in aquatic ecosystems, with a focus on algicidal interactions. Bacteria can control algal growth through physical association or the production of algicidal compounds. The article highlights the specificity of bacterial control, mechanisms for activity, and chemical and biochemical analysis of these interactions. It also reviews the development of environmentally friendly or sustainable methods using algicidal bacteria or compounds derived from bacteria to control harmful algal blooms. The article concludes with potential avenues for future research and the further development and application of bacterial algicides.

Summary: A harmful algal bloom caused by Chrysochromulina leadbeateri resulted in severe fish mortality in northern Norway in spring 2019. This study examines the succession dynamics of the marine microbiome associated with the bloom and identifies coblooming patterns of bacteria and microeukaryotes. The study reveals that the blooming patterns were distinct between different geographically separated stations and were poorly connected to environmental conditions, indicating the importance of biological interactions in shaping the dynamics of harmful algal blooms.

Summary: The impact of the rapidly changing Arctic on zooplankton community structure and seasonal behavior is not yet understood. Zooplankton in the Arctic region is more dependent on surrounding water mass characteristics, such as salinity and depth, rather than geographical location. Seasonal changes in the community are closely linked to algal food availability and seasonal changes from winter to spring.

Summary: In subtropical coastal waters around Hong Kong, the levels of dissolved oxygen (DO) experience significant diurnal changes during algal blooms. The carbon to chlorophyll-a ratio (CCHL) is a critical parameter in water quality models, but predicting its values during high productivity conditions remains challenging. By using a submerged Imaging FlowCytobot (IFCB) and real-time water quality monitoring, the dynamics of phytoplankton and DO are studied in a semi-enclosed tidal inlet. The findings suggest that the CCHL ratio varies significantly over a bloom cycle and can be better predicted by considering algal growth rate and light saturation intensity.
