Summary: The Mar Menor coastal lagoon has experienced severe degradation caused by nutrient pollution over the past three decades. The bloom of cyanobacteria in 2015 resulted in a significant ecological change. Our analysis reveals that the phytoplankton in the years 2016-2021 did not exhibit a seasonal variability pattern, with diatoms dominating the community and occasionally reaching high abundance levels above 10^7 cells L-1 along with chlorophyll a concentrations exceeding 20 μg L-1. The taxonomic composition, temporal variation patterns, and cell abundance of phytoplankton during this period differed significantly from the data prior to 2015, indicating a profound change in the trophic status of the lagoon.

Summary: The research reveals that acidification and deoxygenation are occurring in the bottom waters of the Peter the Great Bay in the Japan/East Sea, particularly at a maximum rate around 750 meters. Climate change is causing a decrease in pH and dissolved oxygen concentrations, while increasing levels of CO2 partial pressure and nutrient concentrations. The variability in hydrochemical properties can be explained by the slowdown in vertical ventilation of the water column and eutrophication.

Summary: This study investigates the seasonal variability of the carbonate system in the eastern Mediterranean Sea, specifically focusing on the North Western Levantine Basin. The findings show that changes in A(T) and C-T in the NWLB are unique due to the interplay between evaporation and autotrophic processes, impacting seawater pCO(2)(SW). The study also highlights significant ocean acidification and a decrease in oceanic surface pH(T)(25) driven by increased atmospheric CO2 and unexplained temporal changes in surface A(T) content.

Summary: The study suggests that phytoplankton diversity indicators are efficient for environmental assessments, but further testing on a broader spatial scale is recommended. Expert knowledge can be used to define impact categories and consider specific pressure types in sub-regional assessments in the Mediterranean Sea. Different diversity indices can distinguish between impact levels, especially showing higher sensitivity in the southern and eastern regions.

Summary: This study simulates and analyzes the impact of a high CO2 emission scenario on the Mediterranean Sea ecosystem. It reveals that under this scenario, plankton primary production and total system respiration increase. However, the increase in productivity is smaller than that of respiration, resulting in decreased concentrations of total living carbon, chlorophyll, particulate organic carbon, and oxygen in the surface layer, and increased DIC pool throughout the basin. Additionally, the dissolution of atmospheric CO2 leads to increased carbon fluxes, reduced organic carbon, and increased inorganic carbon. The eastern sub-basin accumulates more than 85% of the absorbed atmospheric CO2. A clear signal of ocean acidification is observed in the entire basin, similar to other oceans, and can be detected even in the deep layers.

Summary: We conducted a mesocosm experiment to examine the effects of ocean acidification on prokaryotic and eukaryotic communities on single-use drinking bottles in eutrophic waters. High CO2 levels significantly altered the prokaryotic community, increasing the relative abundance of Planctomycetota. Under high CO2, prokaryotes in the plastisphere showed enhanced nitrogen dissimilation and ureolysis, suggesting that ocean acidification may modify nutrient cycling.

Summary: Data on the independent or combined effects of ocean acidification and warming on coastal eutrophication and organic pollution are limited. Acidification favors eutrophication and organic pollution, while warming inhibits these two variables. However, the interaction between acidification and warming in the future may exacerbate organic pollution but mitigate eutrophication.

Summary: We studied the metabolic activity of Heterostegina depressa under different light conditions. The photosynthetic performance and isotope uptake of the specimens were measured. Light supply significantly affected the photosynthetic performance, while the photosymbionts and holobionts could survive and be reactivated after prolonged darkness. The assimilation of C-13-carbonate and N-15-nitrate is mainly controlled by the photosymbionts, while N-15-ammonium and C-13-glucose utilization is regulated by both the symbiont and the host cells.

Summary: The Cape Verde Frontal Zone (CVFZ) is a highly dynamic region with large fluxes of sinking organic matter. The distribution of dissolved and suspended particulate organic matter in this area is influenced by the position of transects and different water masses, indicating the role of biogeochemical processes in shaping water mass properties. However, mineralization of DOM and POM is low, highlighting the importance of sinking fluxes of organic matter for mineralization processes.

Summary: Phytoplankton-derived organic matter plays a crucial role in sustaining heterotrophic marine life in regions with no terrestrial inputs. This study investigates the dynamics and drivers of the dissolved and particulate fractions of fluorescent organic matter (FOM) in the Southern Ocean. The results show that filtration has negligible effects on the fluorescence intensities of the visible FOM spectrum, indicating that dissolved fluorophores contribute the most to this signal. Additionally, protein-like fluorescence is primarily associated with particles, accounting for up to 90% of the total protein-like FOM.

Summary: Ocean acidification and plastic pollution are escalating threats to global societies and ecosystems. Laboratory experiments show that abiotic plastic degradation results in a decrease in seawater pH, particularly in aged plastics. Solar radiation enhances the pH decrease, likely due to the release of organic acids and the production of CO2. Plastic leaching could lead to a seawater pH decrease up to 0.5 units in coastal areas, comparable to the projected decrease by the end of the twenty-first century.
