Summary: Climate change poses a serious threat to coral reefs, leading to coral bleaching and mortality, and global mass coral mortality events highlight the importance of mitigating climate change to protect coral reefs. Local stressors such as high abundance of macroalgae or urchins intensify coral loss and in combination with increasing heat stress, exacerbate coral mortality. Effective local management practices, combined with global efforts to mitigate climate change, offer hope for the survival of coral reefs in the Anthropocene era.

Summary: We developed a semi-closed coral culture micro-device system that provides accurate and programmable temperature control, a sterile initial environment, stable water quality, adjustable dissolved oxygen concentration, and customized light spectrum for corals. The modular design allows for upgrades or modifications by installing new modules or removing existing ones. Under appropriate conditions and proper maintenance, the corals can survive for at least 30 days. This system supports research into the symbiotic relationship between corals and microorganisms and can be used for quantitative monitoring of sea corals.

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: Deoxygenation poses a major threat to coral reefs, causing catastrophic effects such as mass coral mortality. Different coral species have different tolerances to reduced dissolved oxygen concentrations, with some species surviving only a few days while others can tolerate deoxygenation for weeks. This study found that severe deoxygenation had a significant negative impact on recruit survivorship in certain coral species, highlighting the importance of considering species-specific variations in deoxygenation tolerance during reef conservation and restoration efforts.

Summary: This study examines the ability of downscaled cyclones to represent observed cyclone characteristics that affect wave damage to Australian coral reef regions. The research finds spatial uncertainties in downscaled cyclogenesis and track positions limit estimates of reef damage, and the downscaled tracks perform differently for different regions. The study also suggests that there is no clear evidence that cyclones will cause more damage to Australian coral reef regions in the future.

Summary: Coral reefs are at great risk due to ocean warming, and it is important to identify areas where they can survive rising temperatures. This study analyzes data from a global ocean simulation and reveals regional differences in temperature variability caused by internal gravity waves. The results show that thermal refugia are limited to specific depths and locations, with Southeast Asia, the Coral Triangle, the Galapagos, and certain areas along the Pacific shelf of Central America being potential beneficiaries of cooling induced by internal gravity waves.

Summary: The global impacts of climate change are evident in every marine ecosystem, particularly on coral reefs where mass coral bleaching and mortality are common responses. Linking information across scientific disciplines and scales is a major challenge, but adopting an integrative approach can advance coral-reef science and guide conservation efforts. Establishing networks of protected reefs across national boundaries may be the best chance for corals to persist through climate change.

Summary: The diversity of colors in fish communities is directly related to the composition of the local environment, with areas of complex coral cover supporting more diverse and brighter colored fish species. However, global environmental changes and human-induced disturbances can lead to significant declines in the perception of color in fish communities.

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: This article examines the propagation of large nonlinear internal solitary waves (NLIWs) in the northeastern South China Sea, finding that their energy flux and dissipation are significantly higher than the surrounding ocean. Through observations, it is discovered that during the transformation of these waves in shallow water, phenomena such as reflection, refraction, and breaking may occur, and upslope penetration is influenced by the incident wave's amplitude, direction, and local stratification.

Summary: Numerical modeling is used to study how cross-shore flow is affected by steady alongshore currents and shear-generated turbulence. The results show that shear-driven vertical mixing reduces temperature gradients and decreases cross-shore thermal exchange with increasing alongshore current speed. Alongshore flow can enhance or diminish the baroclinic cross-shore exchange flow, depending on its strength, ultimately leading to a dominance of Ekman dynamics for exchange.

Summary: Dissolved oxygen (DO) is an important ecological variable, and its levels can be affected by both thermal stress and hypoxia. In this study, we examined the physical processes that regulate hypoxia and temperature inversions in Bahia Almirante, a tropical embayment in Panama. We found that seasonal temperature inversions and hypoxia frequently co-occur, with more severe impacts in the back bay. High freshwater input and salinity stratification were identified as important factors contributing to these events. Understanding the dynamics of these stressors is crucial for marine organisms in similar shallow, tropical estuaries.

Summary: This study presents a modeling study of internal tides propagating around an idealized island. It shows that subcritical slope has the greatest potential for creating favorable conditions for benthic organisms through enhanced upwelling. These findings are important for understanding the propagation of internal waves and the characteristics of water flow around islands.

Summary: Net-zero greenhouse gas (GHG) emissions targets are driving interest in biomass-based negative emissions and bioenergy from marine sources. This study assesses the costs and climate benefits of global seaweed production using growth and technoeconomic models. The results indicate that seaweed-based climate benefits are feasible, but further research is needed to reduce economic and biophysical uncertainties.

Summary: Oceanic internal gravity waves propagate along density stratification in the water column and can travel thousands of kilometers before breaking in shoaling bathymetry. Despite the difficulty in detecting them, a potential method using seismic signals for detection has been proposed and could lead to expanding the historical record of internal waves.
