Summary: Oyster reef restoration is a widely used coastal restoration intervention, but its impact on the chemistry of surrounding seawater and the vulnerability of oysters to acidification is still unclear. This study characterized the growth of constructed reefs and examined the pH and carbonate chemistry of reef-influenced seawater. The results showed that reef communities modified seawater carbonate chemistry, increasing oyster vulnerability to acidification.

Summary: This study examines the impact of aquacultured eastern oysters on carbonate saturation states in estuarine waters. The results show that oysters can significantly lower carbonate saturation states, and this impact may increase with climate change and industry expansion.

Summary: The effects of global acidification on marine organisms' shells are of great interest. This study focuses on the protective role of the outer organic periostracum in gastropods living in acidified estuarine waters. The formation of a clay shield, directed by the organism, was found to protect against shell dissolution.

Summary: The study found a significant negative relationship between the metabolic rate and bacterial richness in oysters, with the bacterial community composition being influenced by metabolic rate, extracellular CO2, and extracellular pH. The effects of extracellular CO2 depended on genotype, and changes in metabolic rate aligned with a shift in ASVs abundance, indicating a clear relationship between host metabolism and the microbiome in oysters.

Summary: Hypoxia and acidification are commonly linked in eutrophic aquatic environments. The degree of their coupling, however, has not been adequately assessed. This study used a box model and 20 years of data to explore the relationship between hypoxia and acidification in Chesapeake Bay. The results suggest that aerobic respiration and calcium carbonate dissolution contribute to the levels of dissolved oxygen, pH, and DIC in the bay's bottom waters, with varying effects during different seasons. These findings have implications for the management of co-stressors in estuarine systems.

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: 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: 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: 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: This study presents a field application of a fully automated submersible spectrophotometric analyzer for high-resolution in situ pH measurements in dynamic estuarine and coastal waters. The LOC sensor was deployed for 6 weeks and showed stable and accurate pH measurements, as validated against laboratory analysis.

Summary: Carbonate-poor sandy sediments play a crucial role in neutralizing ocean acid. The dissolution process varies with changes in seawater conditions and is similar to observations in carbonate-rich sediment environments. As acidification continues, carbonate-poor sediments may shift from being an acid source to providing buffering capacity.

Summary: Ocean acidification can affect marine molluscs, but transgenerational plasticity may mitigate some effects. This study investigated how the microbiome can be influenced by transgenerational exposure to ocean acidification in Sydney Rock oysters. The results showed that parental exposure to elevated PCO2 altered the bacterial community composition in both eggs and larvae, with certain Rhodobacteraceae ASVs increasing or decreasing in abundance. These findings suggest that the transfer of maternal microbiomes to larvae is affected by exposure to ocean acidification and may contribute to transgenerational plasticity.

Summary: This study used Pacific oysters as a model to investigate apoptotic responses and regulation mechanisms under short- and long-term CO2 exposure. The findings suggest a variety of apoptosis regulation mechanisms exist during different exposure periods, with CgBcl-XL playing a crucial antiapoptotic protein role under long-term CO2 exposure.

Summary: Ocean acidification caused by the absorption of atmospheric CO2 by the oceans has detrimental effects on marine organisms, including the vulnerable eastern oyster. This study investigated the challenges oysters face in low pH conditions and identified potential resilience mechanisms, such as food availability and adaptive changes in food uptake. The findings suggest that oysters with abundant food resources are more likely to survive and grow under ocean acidification, highlighting the importance of energy availability in their resilience.
