Summary: The importance of animals in mediating ecosystem processes has long been recognized by ecologists, as they play critical roles in both consumptive pathways like predation and herbivory, as well as in bottom-up pathways associated with nutrient dynamics. Research has shown the significant impact of consumer-mediated nutrient dynamics in terrestrial, freshwater, and marine ecosystems, inspiring further studies on their role in ecosystem function. This study provides comprehensive data on consumer nutrient dynamics in subtropical and tropical Caribbean coastal marine waters, offering valuable insights for advancing ecological theory and applied science in tropical marine ecosystems.

Summary: This study investigates the underwater noises generated during offshore exploratory drilling (OED) at the Xiamen port. The results show that hammering noise is an impulsive sound with a dominant frequency below 10 kHz, while vibrating and drilling noises are non-impulsive sounds with fundamental frequencies of 41 Hz and 45 Hz, respectively. The impact assessment on marine mammals reveals that hammering noise poses a high risk of hearing damage up to 300 meters for certain groups, while drilling noise only causes damage within approximately 40 meters. It is recommended to establish a warning zone with a radius of 1.9 km during OED construction.

Summary: The report "Environmental Impact Assessment of the Parc Tramuntana project" aims to provide a specific analysis of the project's environmental impacts. Being the first offshore wind project in the Catalonian waters, it has generated a strong social debate due to the lack of relevant references in this area. The report evaluates the potential impacts based on detailed information and quantitative data, presenting initial conclusions that categorize the impacts as moderate on aspects such as turbidity and sedimentation, underwater noise, hydrodynamic circulation, and electromagnetic field alteration.

Summary: This study found that under future climate conditions, the three dominant colonizing species on offshore wind farms increase their potential for clearing suspended food particles, with ocean warming and acidification having antagonistic effects on their growth. The experimental results demonstrate how ecophysiology underpins functional responses to climate change in these environments, highlighting for the first time the integrated, cascading potential effects of offshore wind farms and climate change on the marine ecosystem.

Summary: When planning wind farms, optimizing the layout is crucial for increasing production and reducing costs. This paper focuses on minimizing the levelized cost of energy (LCOE) for a floating wind farm using wind data in Porto Santo, Portugal. The ensemble based optimization (EnOpt) method is employed to handle the layout problem with multiple constraints, and the extended version called EPF-EnOpt outperforms other methods in reducing LCOE and computational cost. It is also found that EPF-EnOpt performs the best in maximizing annual energy production without considering costs.

Summary: An approach is developed for planning the logistics and installation aspects of a floating wind farm, considering the complexity of the problem due to specific constraints in transportation and manufacturing. The planning tool is based on the analysis of different logistical solutions and aims to ensure the coherence between logistic methods and project performance. A case study is performed for the CENTEC TLP concept in Spanish and Irish waters, revealing the major aspects affecting design and logistics factors. The tool is applicable for the preliminary design of wind farms worldwide.

Summary: This study evaluates the impact of offshore wind farm decommissioning on local benthic macrofauna biodiversity. The results suggest that preserving the scour protection layer can help preserve a significant number of species, while removing the foundation structure benefits the fauna of structures without scour protection. However, further validation is needed due to limited data availability.

Summary: Governments worldwide are facing challenges in offshore renewable energy development (ORD) due to a lack of understanding of the environmental consequences, especially on protected birds. The impacts of ORD on marine birds are complex and uncertain, hindering the decision-making process. This study reviews the methods used in the UK to estimate ornithological ORD impacts and proposes a framework to quantify and reduce uncertainty, providing recommendations for future risk reduction. These findings have implications for impact assessments in other countries as well.

Summary: Wind is a significant environmental load on offshore engineering structures, especially in the case of offshore wind turbines. The current international standards for wind load assessment and structural response may underestimate the actual load and response, highlighting the need for improvements and revisions.

Summary: This study introduces a novel coupling approach considering the impact of inhomogeneous wave loads on monopile-supported wind turbines in wind farm layout optimization.
By optimizing the layout, the total wave load of the wind farm can be minimized while maintaining a favorable annual energy production.
Experimental results show that the coupling optimization has significant benefits in reducing wave loads by 20.1%-40.5% while still preserving a favorable amount of AEP.

Summary: This study aims to explore how actors in the offshore wind farm decommissioning supply chain collaborate to manage collective uncertainties. Semi-structured expert interviews were conducted with ten companies in the Netherlands, Germany, and Belgium. The findings suggest that businesses currently utilize collaborative communication, information sharing, and joint knowledge creation to mitigate the adverse effects of collective uncertainties. However, barriers such as intellectual property or the lack of resources severely impede collaboration.

Summary: The operational principle of offshore wind farms is to extract kinetic energy from the atmosphere and convert it into electricity, generating wind-wakes and affecting surface stress and Ekman transport. This study provides empirical evidence of wind-wake induced upwelling/downwelling dipoles and characterizes their development, operation, and erosion phases.

Summary: The study found that most European eels passing through pumping stations in Friesland, the Netherlands, pass the stations within a day, while a few eels may stay for several weeks. Prioritizing pumping stations based on degree of blockage, mortality rates, and importance for migratory fish can maximize the effectiveness of measures and mitigation taken to protect the migrating population.

Summary: Bycatch is a significant threat to cetaceans worldwide, with bottom-set gillnets posing a specific risk to harbor porpoises. Methods to assess bycatch rates include on-board observers, electronic monitoring, and fishermen reporting, but systematic approaches are lacking. Necropsies of stranded animals provide insights into bycatch occurrence and health status, but uncertainties remain due to the absence of specific diagnostic tools for underwater entrapment.
