Summary: The burning of fossil fuels is causing rapid global ocean warming and acidification, stressing the physiological limits and plasticity of many marine species. Antarctic species are particularly vulnerable to environmental changes, with warming affecting the growth rate of otoliths in juvenile emerald rockcod, while CO2-acidified seawater has no effect.

Summary: This study investigates the effects of ocean acidification on the interaction between Hydrozoa and fish larvae. It found that under ocean acidification conditions, the abundance of Hydrozoa increased but its biomass decreased. At the same time, the survival rates of Atlantic herring larvae were higher. These results suggest that ocean acidification indirectly affects the Hydrozoa-fish relationship through changes in the phyto-, micro-, and mesoplankton community.

Summary: Based on the analysis of fish otolith assemblages from surface sediments of the Lomonosov Ridge in the Arctic Ocean, it has been found that low sedimentation rates and the sorting of fine sediments result in the mixing of Holocene populations at the sediment surface. The presence of sedimentary hiatus during the last glacial maximum allows for the presence of Marine Isotope Stage (MIS) 3 or older specimens in the surface sediment. The study also shows that C-14-stratigraphies from underlying sediments reflect the mixing of Holocene and MIS 3 or older populations, which invalidates continuous age-depth inferences based on C-14 ages. Therefore, caution is needed when using C-14 chronologies for paleoceanographic reconstructions in low sediment accumulation rate environments like the central Arctic Ocean.

Summary: In this study, a 28-day CO2 enhancement experiment was conducted to investigate the effects of ocean acidification on benthic biofilms in intertidal soft sediments. The results showed that the 1000 ppm CO2 treatment significantly altered the biofilm community composition and microbial biogeochemical cycling in sandy sediments. This suggests that benthic biofilms in intertidal sandy sediments are likely to change significantly near the end of the century if anthropogenic CO2 emissions are not mitigated, which has profound implications on local ecosystems and biogeochemical cycling.

Summary: This study indicates that under 60 years of ocean warming and acidification, the shell mineralogy of the California mussel has undergone significant changes, with an increase in shell calcite and a decrease in aragonite content. The results suggest that ocean pH and saturation state play a strong role in mediating the shell mineralogy of this species, highlighting long-term changes in response to ocean acidification.

Summary: The majority of common edible oysters are projected to grow more slowly and have smaller impaired shells due to ocean acidification. This study found that larvae exposed to low pH developed faster and had higher settlement success, while juveniles with parental exposure showed improved survival and growth. Transgenerational effects of parental exposure were found to have a greater influence than within-generational effects of larval exposure on post-metamorphic traits of Crassostrea hongkongensis.

Summary: Understanding the effects of OA and warming trend on marine organisms, particularly on early reproductive traits, is vital for predicting their response to climate change. In this study, exposure to elevated pCO(2) and higher temperatures had significant impacts on the sorus photosynthetic performance and germination rate of meiospores in Lessonia trabeculata, indicating potential threats to the species' establishment and ecosystem functioning.

Summary: The paper discusses the increased economic importance of Arctic Ocean fish stocks under future climate scenarios, highlighting the vulnerability of the Arctic Ocean to ocean acidification and the need to consider it with other stressors to accurately predict fish stock movement towards the Arctic. The roadmap proposed entails improving knowledge through satellite observations, informing experimental studies, regional assessments of vulnerabilities, and implementing appropriate management strategies to address the impact of ocean acidification on Arctic fish stocks.

Summary: Cleaning symbiosis has beneficial effects on clients' ecophysiology, but ocean acidification can decrease cleaners' motivation to inspect clients. In this study, damselfish with access to cleaning stations showed a negative metabolic response to parasite infection, while fish without access to cleaners had a decreased aerobic scope after an acclimation period to high CO2.

Summary: This study demonstrated that reef sediments can transmit Stony Coral Tissue Loss Disease (SCTLD) through indirect exposure between diseased and healthy corals. The study also identified 16 SCTLD indicator taxa associated with coral tissue loss. This research is important for our better understanding of the role of sediment microbial communities and coastal development activities in the persistence of SCTLD in the wider area.

Summary: The National Oceanic and Atmospheric Administration's Coral Reef Conservation Program supports the National Coral Reef Monitoring Program, which conducts standardized observations to assess the status of coral reef ecosystems in the United States. Despite an overall rating of "Good," most coral reefs are declining and vulnerable to further degradation, with climate change impacts being more pronounced than expected.

Summary: Coastal habitats are facing challenges of decreased seawater pH and increased temperature due to anthropogenic climate change. The Caribbean king crab plays a crucial role in Western Atlantic reefs by grazing macroalgae that competes with coral. A laboratory experiment found that juvenile king crabs are tolerant to changes associated with climate change, suggesting they could benefit coral reef restoration efforts to make them more resilient to warming and acidic oceans.

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: In order for reef frameworks to persist, the production of calcium carbonate by corals and other calcifying organisms must exceed the losses caused by erosion. However, this balance is currently threatened by ocean warming and acidification. A modelling approach was developed to forecast habitat persistence under different emission scenarios and to examine the effects of restoration and coral thermal adaptation. The results showed that net carbonate production declines once the threshold for severe bleaching is reached, but mitigation and adaptation can delay the switch from net accretion to erosion.

Summary: Stony coral tissue loss disease (SCTLD) is a major threat to coral reef ecosystems in the Tropical Western Atlantic. Waterborne transmission is the primary mode of spread, and UV treatment of ballast water has limited effectiveness. Ballast water may pose a threat to the spread and persistence of SCTLD.

Summary: To accurately predict the impacts of ocean acidification on shallow-water ecosystems, it is crucial to consider the biogeochemical impact of local benthic communities and the connectivity between offshore and onshore water masses. Estimation of residence time can help quantify this connectivity and determine the influence of benthic ecosystems on the chemistry of the water column. The study provides estimates of nearshore residence time for Guam and demonstrates the importance of including residence time in models to better predict biogeochemical variability in coral reef environments.

Summary: Contrary to expectations, the study found that purebred larval offspring of the nearshore mountainous star coral exhibited higher survival rates and lower stress response gene expression profiles under elevated temperature. One potential explanation could be the compromised reproductive output of the nearshore population due to summer bleaching events, resulting in lower storage lipid content in their gametes.

Summary: This study calculates carbonate budgets for 723 sites across the Florida Reef Tract (FRT) using benthic cover and parrotfish demographic data, as well as high-resolution LiDAR topobathymetry. The results show that the majority of the study sites are in an erosional state, with particularly vulnerable habitat in the Southeast Florida region. Mid-channel reefs in the Florida Keys have the highest net carbonate production and may be crucial for reef development in the region. The study emphasizes the importance of increased protections and management efforts to offset the net erosion of Florida reefs.
