Summary: Oysters are ecological engineers whose role in the aquatic environment remains debated. However, research shows that oyster biodeposition (OBD) significantly decreases total organic carbon and total nitrogen in sediments, alleviating nutrient overload in sediment under oyster farming. Microbial metabolic roles are likely responsible for enhancing carbon/nitrogen flux speed and reducing overall nutrient status.

Summary: Studying the impacts of heatwaves on marine organisms is crucial for understanding their tolerance to heat stress. Integrative analyses across different levels of biological organization reveal non-linear predictions, such as gene-protein-physiology-organism relationships. Formal genetic studies of multigenerational pedigreed families can provide further insights into potential evolutionary responses to rapid environmental change.

Summary: This year-round field study in a mangrove habitat along the coast of South China reveals the significant effects of bio-geomorphic feedbacks on the burial of microplastics. As the strength of these feedbacks declines, the abundance of microplastics decreases, and locations with weaker waves and less sediment erosion have more diverse shapes and colors of microplastics with larger average particle size. These findings highlight the importance of bio-geomorphic feedbacks in shaping the abundance and characteristics of buried microplastics.

Summary: The Mar Menor lagoon in Spain has experienced severe eutrophication, leading to a decline in the population of flat oysters and loss of their habitats not only in the lagoon but also in European seas. The Mar Menor Oyster Initiative aims to understand the nutrient extraction capability of flat oysters and develop tools for restoration and bioextraction. The RemediOS project, part of the initiative, focuses on obtaining oyster seed from local broodstock for population restoration. This study presents the results of the first attempt at reproducing Mar Menor local broodstock in captivity.

Summary: Coastal areas are vulnerable to climate change effects, and oyster-dominated eco-engineered reefs are promoted as tools to enhance coastal resilience. However, the success of these reefs varies across projects and locations, highlighting the importance of understanding factors influencing their effectiveness for future efforts. Site selection, biological dynamics, and interactions with adjacent habitats are key factors influencing the success of these reefs.

Summary: An analytical/numerical model was developed to predict the spatial distribution of biodeposits in suspended aquaculture systems. The model was validated in shallow estuaries and can be used by oyster growers and environmental managers to assess the effect of organic matter deposition.

Summary: The study finds that currents are unable to mobilize unexploded ordnance devices in almost all regions of the North Sea, while certain objects can be mobilized by waves in very shallow and extreme conditions.

Summary: Sediment burial duration was measured in different regions of the Indo-Gangetic Plain in this study, and variations in burial duration were found across different areas. The study showed that even samples close to the mountain front can have burial durations of millions of years. These findings suggest that denudation rates derived from modern river sands or in paleo settings need to consider burial duration and associated processes.

Summary: The study presents a comprehensive dataset of biogenic silica fluxes in the Peruvian oxygen minimum zone, showing that BSi burial and recycling fluxes are highest on the shelf, with greater preservation efficiency compared to global averages. The main control on BSi preservation appears to be the rate at which reactive BSi is transported. Existing global data allow for a simple relationship between BSi rain rate and the accumulation of unaltered BSi, providing the possibility of reconstructing precipitation rates and primary production in sediment archives within global models.

Summary: This study compared the physiological processes and mortality of diploid and triploid oysters, finding that triploids had higher mortality but the measured physiological parameters could not explain it. Further research is needed to determine if disruption of energy homeostasis at the cellular level causes the mortality.

Summary: The coprecipitation of dissolved organic matter (DOM) and phosphate with Fe(III) is crucial in the biogeochemical cycle of organic carbon (OC) and phosphorus (P) in aquatic ecosystems. Our study found that coprecipitation of humic acid (HA) and phosphate with Fe(III) is enhanced as pH decreases or initial Fe(III) concentrations increase. Additionally, the presence of phosphate has a moderate inhibition effect on HA coprecipitation.

Summary: This study evaluates the denitrification associated with floating oyster aquaculture in a tidal salt pond in southeastern Massachusetts. The results show that floating oyster aquaculture can enhance sediment denitrification and reduce nitrogen inputs, but its effectiveness is influenced by season, year, and nitrogen deposition. It is necessary to assess its efficacy in reducing nitrogen in coastal embayments typical of southeastern Massachusetts based on specific conditions.

Summary: Organic carbon in inland waters exists in dissolved or particulate states, with different contributions to carbon cycling. The degradation of organic material into solutes is a common transition, but dissolved organic carbon can also aggregate into particles. Recent research explores the formation of organic particles at the soil-stream interface, advancing understanding of the links between dissolved and particulate OC and their implications for long-term carbon burial and ecosystem functioning in inland waters.

Summary: Regime shifts from a vegetated state to a turbid state have been found to impact the burial ability of polycyclic aromatic hydrocarbons (PAHs) in sediment, with higher hydrophobic PAHs showing a stronger decrease in burial ability. This study provides insight into the fate and potential risks of hydrophobic organic contaminants (HOCs) in waters affected by eutrophication-induced regime shifts.
