Summary: The study shows that the coupling of ocean acidification and hypoxia significantly increases N2O production, but there is an antagonistic relationship between the two when they exist individually. Overall, the hypoxia treatment weakens the effects of ocean acidification, leading to an increase in N2O production. Under future climate change scenarios, N2O production in the coastal waters of the Bohai Sea may increase.

Summary: Anthropogenic climate change has led to warming temperatures and decreased oxygen concentrations in the global oceans. Research conducted in the Southern California Channel Islands over a 15-year period showed that many fish species shifted their peak distribution to shallower depths in response to declining oxygen levels. This climate-driven distribution shift has important implications for fisheries management, including habitat reduction, compression, trophic dynamics, and body condition.

Summary: Funded by the German Research Foundation, the research project 'SFB 754, Climate - Biogeochemistry Interactions in the Tropical Ocean' aimed to investigate climate-biogeochemistry interactions in the tropical ocean, with a focus on oxygen distribution processes. Over three 4-year funding phases, a consortium of over 150 scientists conducted 34 major research cruises, collecting extensive physical, biological, chemical, and meteorological data, with an agreed common data policy ensuring openness in data publication.

Summary: The Indian Ocean Dipole (IOD) plays a crucial role in influencing the Arabian Sea oxygen minimum zone (ASOMZ). Negative IOD events lead to a decrease in the suboxic area, while positive IOD events result in an expansion. The response of the ASOMZ in the Gulf of Aden is primarily regulated by physical factors, while the ASOMZ in the central Arabian Sea is influenced by both biological and physical processes.

Summary: Research suggests that enzymes involved in organic matter catabolism are kinetically limited by oxygen at concentrations much higher than those required for respiration. The proposed hypoxic barrier hypothesis may help explain why many ocean ecosystems rarely reach anoxic conditions, by highlighting the kinetic properties of oxygen-dependent reactions and their impact on ecosystem trajectories under oxygen stress.

Summary: The study revealed that changes in photosynthetic and respiration rates in coastal marine habitats can lead to considerable variability in ecosystem metabolism on different time scales, from diurnal to seasonal. Different habitats showed diverse responses to changes in pH and DO, emphasizing the importance of enhancing seagrass and macroalgae cultivation to maintain estuarine ecological balance in the face of predicted declines in pH and oxygen levels.

Summary: The vertical distribution of zooplankton in the Eastern Tropical North Pacific is limited by oxygen, particularly in the Oxygen Minimum Zone. Zooplankton carbon density remains relatively constant above 100 meters depth, and is available during both day and night.

Summary: The decrease in ocean pH and the presence of dissolved copper have negative impacts on the calcification, photosynthesis, and respiration of the tropical Stylophora pistillata coral. The effects are amplified when both stressors are combined.

Summary: The Arabian Sea is known for its highly productive marine ecosystem and the thickest oxygen minimum zone (OMZ) due to intense productivity and sluggish circulation. Recent evidence suggests a decline in oxygen levels in the northern Arabian Sea. However, future projections of the OMZ are uncertain due to inconsistencies in models. The limitations of current models and the sensitivity of oxygen supply and consumption to local and remote changes pose challenges in predicting future changes in the Arabian Sea OMZ.

Summary: Recent studies suggest that terrestrial organic carbon is transported laterally from continental margin to open ocean, supporting the heterotrophic production in the ocean. The actual sink mechanism of terrestrial organic carbon in the ocean remains unresolved, with priming effect speculated as a possible mechanism. Nutrient scavenging could be the dominant mechanism of priming effect in oxygen minimum zones according to current studies.

Summary: Dark carbon fixation in the ocean twilight zone plays a crucial role in carbon sink. This study analyzed the rates of dark carbon fixation in the Arabian Sea twilight zone and found that the rates were higher in suboxic oxygen minimum zone (OMZ) waters compared to hypoxic OMZ waters, due to the presence of chemoautotrophic ammonium oxidizers and anammox bacteria. The extrapolation of these rates to the global ocean suggests that dark carbon fixation contributes significantly to the sinking carbon fluxes.

Summary: This study investigated the dynamic nature of hypoxia and acidification in eutrophic estuaries through continuous measurements, revealing their potential impact on marine food webs. The results showed high rates of respiration, diurnal variations in water column pH and dissolved oxygen, and contributions of nitrification and oxidation processes to acidification in these environments.

Summary: This study examines the impact of global ocean oxygen loss on the largest oxygen minimum zone (OMZ) in the tropical Pacific using Earth system models. The projections suggest a consistent pattern of expansion of low oxygenated waters, slight contraction of the OMZ core, and spatial redistribution of hypoxic waters. Changes in circulation and biology drive these shifts, with reduced subtropical ventilation controlling the expansion and a combination of circulation and biological changes explaining the contraction.
