Summary: The study evaluates coral reef community structure and reef processes across a strong natural gradient in pH and aragonite saturation state. It finds that net carbonate accretion rates are sensitive to declining omega(ar), while benthic ecological metrics show fewer direct responses to lower-omega(ar) conditions. This highlights the importance of monitoring coral reef net carbonate accretion as a critical tool for assessing the long-term impacts of ocean acidification.

Summary: Climate change affects the sexual reproduction and photosynthetic capacity of Red Sea coral, leading to changes in reproductive timing and synchronicity. Survival and metamorphosis rates of offspring reared under simulated conditions are significantly reduced, highlighting potential long-term impacts on the coral population.

Summary: This paper presents a framework for assessing the readiness of policy to address ocean acidification, focusing on coral reefs as a case study. The framework encompasses six dimensions that encompass comprehensive preparation for the impacts of ocean acidification and other anthropogenic hazards. Standardized indicators are defined, leading countries are identified, and the case study of Australia, with its largest coral reef system, is evaluated. The framework provides a rubric for self-assessing policy preparedness and prioritizing future endeavors.

Summary: The Great Barrier Reef is facing threats from climate change and local stressors, with its condition degrading over recent decades. This study demonstrates that artificial ocean alkalinisation can help reverse the impact of global ocean acidification on the GBR reefs, but it would be expensive, have unknown risks, and require continuous effort until atmospheric CO2 concentrations return to today's levels, likely centuries in the future.

Summary: Ocean acidification is expected to affect coral reef ecosystems by changing calcification, bioerosion, and physiology of marine organisms. The study found that diurnal fluctuations in carbonate chemistry can impact the bioerosion rates of sponges, and this effect may be intensified by photosynthetic symbionts.

Summary: This study examines multiple coral species from two CO2 seeps in Papua New Guinea to assess their ability to control their calcifying fluid chemistry. The researchers find that corals living in low but highly variable pH environments have a greater ability to maintain constant CF pH. However, corals with limited pH reduction in less variable low pH seawater tend to be more abundant at the seep sites. The findings suggest a potential association between ecological success and greater pH homeostasis, but more research is needed.

Summary: Projecting the effects of climate change on net reef calcium carbonate production is crucial, especially considering corals' natural adaptive capacity to such change. This study estimates how symbiont evolution and shuffling may influence responses to ocean warming and acidification under different emissions scenarios. The results show that symbiont adaptive capacity can favor positive net reef calcium carbonate production, but the projections vary spatially and by emissions scenario.

Summary: Total alkalinity (TA) is widely used as a parameter in carbonate system calculations, but organic alkalinity (OrgAlk) in coastal waters contributes to TA and affects the accuracy of carbonate calculations. This study investigates the prevalence and properties of OrgAlk and its impact on carbonate chemistry calculations in a transitional waterbody.

Summary: Global coral reef calcification is primarily driven by depth and benthic calcifier cover. Repeatedly studied reefs are experiencing an annual decline in calcification rates of 4.3% and an increase in organic productivity of 3% since 1970. This indicates a shift in essential metabolic processes of coral reef ecosystems, potentially leading to net dissolution worldwide around 2054.

Summary: Coral reef ecosystems are projected to experience significant declines due to ocean warming and acidification. This study examines the environmental resilience of over 650 coral species and predicts a substantial decrease in coral species richness globally, with a potential net loss ranging from 73% to 91% by 2080-2090. The Great Barrier Reef, Coral Sea, Western Indian Ocean, and Caribbean are expected to be severely impacted. Mitigating climate change is crucial to prevent massive coral species extinctions.

Summary: Studies have shown that the influence of increasing atmospheric CO2 and climate change on the marine CO2 system and ecosystems is mainly manifested in the variability of carbonate chemistry, including seasonal and diurnal variations. Models project that the future ocean will experience enhanced diurnal variability of pCO2 and [H+], which may impose higher metabolic costs on marine organisms.

Summary: The interplay between ocean circulation and coral metabolism creates highly variable biogeochemical conditions in space and time across tropical coral reefs. By simulating these variations using a coupled model, we find that coral reefs have complex spatial and temporal structures, and different biogeochemical niches may have significant impacts on the health of corals.

Summary: This study investigated the effects of seawater total alkalinity (TA) levels on the growth and calcification of Pacific abalone. The results showed that TA downregulation led to reduced growth and thinner shells in the abalone, while TA upregulation improved growth performance. The decline in CO2 buffering capacity and calcium carbonate saturation state (Omega) in TA-downregulated seawater were identified as potential reasons for the negative effects on abalone growth. Therefore, it is important to consider the entire carbonate chemistry rather than just seawater pH and pCO(2) when assessing the impact of ocean acidification on abalone. Cultivating abalone in seawater with higher CO2 buffering capacity and Omega, achieved through integrated culture with seaweed or increased TA levels, is recommended.

Summary: Unregulated fish mariculture in Bolinao, Philippines has resulted in regional eutrophication and localized acidification of coral reefs. Water quality and carbonate chemistry parameters show variations between seasons. The study highlights the need to address both global acidification and local disturbances caused by fish mariculture.

Summary: Recent assessments have focused on the risks posed to atoll habitability by various climate-related drivers, with different levels of risk identified in the Western Pacific, Central Pacific, and Central Indian Ocean regions. The study found that urban islands may face varying levels of risk depending on geomorphology and local disturbances, while rural islands are likely to experience consistently high risks in the second half of the century.

Summary: This study provides a data-driven assessment of the global extent and production of macroalgal habitats, revealing that macroalgal forests are a significant biome with a large area and high productivity. They are globally distributed as a thin strip along shorelines and their expansion in polar, subpolar, and tropical areas may increase their contribution to global carbon sequestration.

Summary: This study reveals that the Mediterranean Sea has experienced exceptional thermal conditions, leading to five consecutive years of mass mortality events of marine organisms. The occurrence of these events is significantly related to the heat exposure from marine heatwaves observed at the surface and depths. The Mediterranean Sea is facing an unprecedented threat to its ecosystem's health and functioning due to the accelerated ecological impacts of marine heatwaves.

Summary: The Arctic Ocean is experiencing high rates of ocean warming and acidification, which have significant impacts on marine organisms and ecosystems. However, data on the carbonate system in the Arctic region are limited. This study presents the first high-frequency and multi-year dataset of salinity, temperature, CO2 partial pressure, and pH in a coastal site in Kongsfjorden, Svalbard. The findings indicate seasonal variations in the saturation state of calcium carbonate and a consistent lower pCO(2) than atmospheric CO2, suggesting this site acts as a sink for atmospheric CO2.

Summary: Mangrove forests, seagrass meadows and tidal saltmarshes are vegetated coastal ecosystems that store large quantities of carbon. Protecting and restoring coastal blue carbon ecosystems can reduce greenhouse gas emissions and increase carbon dioxide absorption and storage. Restoration of coastal vegetation has benefits for climate adaptation, coastal protection, food provision and biodiversity conservation.
