Summary: The Western Australian margin is a unique coral reef province with modern coral reef development occurring at latitudes as far south as 29 degrees S. The genesis of this coral reef province may go back to the Oligo-Miocene, with seismic reefs being only sparsely sampled and present in a few remote locations. The study investigates middle Miocene shallow-water limestones with tropical fauna formed along the North West Shelf, showing warm climate during this time despite being located further south than its present position.

Summary: The study on the reef-lagoon system at Ningaloo Reef, Western Australia, using the SWASH model, revealed that wave forces primarily drive onshore flows near the reef crest, while bottom stress plays a significant role in wave setup inside the lagoon.

Summary: The Low-Voltage Mineral Deposition technology (LVMD), also known as Biorock, is suggested for coral reef restoration due to its high porosity, wide pore-size distribution, and durability. This paper highlights the engineering value of LVMD as artificial reef material, showing its similarities with coral properties and potential for sustainable intervention in marine environments. Comparing LVMD, High-Voltage Mineral Deposition (HVMD), and Coral Porites Exoskeleton (CPE) reveals their similar chemical-physical characteristics, supporting their use in coral reef restoration and construction.

Summary: This study reveals that the presence of GO nanosheets can have negative effects on the behavior, physiology, and biochemistry of benthic organisms such as H. diversicolor, suggesting that the increase of this engineered nanomaterial in the environment may disturb the benthic community and have repercussions on estuarine ecosystems.

Summary: In reef-lagoon systems, suspended sediment is primarily transported close to the seabed and influenced by wave frequencies. Mean currents are the main transport mechanism, contributing significantly more suspended-sediment flux than sea-swell and infragravity waves.

Summary: The study assesses the performance efficiency of lagoon mid-water rope nurseries for coral gardening in two different atolls in the Maldives for the first time, indicating that it is an effective technique. The survival rates and growth rates of different coral genera were detailed, revealing the potential for application in wider scale coral gardening practices in the Maldives.

Summary: Anthropogenic stressors have resulted in coral mortality, leading to loss of coral cover and decreased structural complexity, which threatens reef biodiversity, functioning, and ecosystem services. However, the specific species affected and the traits that make them susceptible to reef flattening are not well understood. This study identifies important traits that mediate the responses of fish species to reef degradation.

Summary: Marine heatwaves are increasing in frequency and intensity, impacting coral reef fisheries indirectly through habitat degradation. A study found that the 2016 heatwave had both direct and indirect effects on the Great Barrier Reef's largest reef fishery, with temperature affecting fish catch rates and biomass. The research highlighted the potential large effect of heatwaves on catch rates of reef fishes, independent of changes in reef habitats.

Summary: There is a significant difference in the treatment of organic versus inorganic UV filters in politics and in the 'reef safe' sunscreen market, which is currently not scientifically justified. A risk-based approach with equal consideration of organic and inorganic UV filters is recommended for future regulatory measures as well as a clear definition and regulation of the 'reef safe' terminology. The market analysis revealed that the majority of surveyed sunscreens contain inorganic UV filters and various unregulated claims are used in the marketing of 'reef safe' products.

Summary: Wave nonlinearity can impact sediment transport and nutrient delivery on coral reefs, but previous studies have not fully considered the effects of currents. In this study, 3D reef-lagoon-channel experiments were conducted to analyze wave height distribution and wave nonlinearity evolution. By incorporating the current velocity, the accuracy of estimating wave skewness and asymmetry was significantly improved. The influence of the Doppler effect on wave shapes varied with wave heights and reef submergences.

Summary: This study investigated the intestinal fungal diversity of three coral reef fish and found that fungal communities in the intestines are influenced by their surrounding environments. The distribution of fungi in fish intestines may be related to the physiological functions of different intestinal segments. Some fungal isolates showed antimicrobial activity against marine pathogenic microorganisms.

Summary: This study found that the Great Barrier Reef is negatively impacted by the combined effects of the contaminant diuron and climate change, particularly affecting the physiological responses of corals, with photosynthesis being significantly affected. It suggests that water quality guideline values may need to be adjusted as climate conditions change.

Summary: By conducting impact experiments using a split Hopkinson pressure bar device, the dynamic mechanical properties and damage characteristics of coral reef limestone (CRL) were investigated. The effects of growth line inclination, strain rate, and density on CRL's dynamic mechanical properties were analyzed, and their damage characteristics were estimated through quantitative analysis. The results showed that CRL had a longer elastic stage and a shorter failure stage compared to porous rock-like materials, and its porous properties were not apparent. The dynamic peak stress of CRL decreased gradually with increasing growth line inclination, and the strain rate effect on dynamic peak stress was dependent on density.

Summary: This article investigates the impacts of tides and waves on water renewal in the Toliara lagoon in Madagascar. Through numerical modeling and data validation, the study found that under different wave conditions, tides and waves interact to affect the direction and intensity of cross-reef flow in the lagoon.
