Summary: Wind-generated surface waves can cause an increase in mean water levels, known as wave setup. A common way to simulate wave setup is by assuming a balance between the barotropic gradient and the radiation stress associated with breaking waves. However, field observations suggest that this approach underestimates wave setup near the shoreline. This study investigates the effects of depth-varying wave forcing on wave setup prediction, leading to improved accuracy in the surf zone.

Summary: This study examines the performance of different wave height distributions in the surf zone on the central west coast of India. The results show that the Rayleigh and Exponential pdfs are not a good fit for the surf zone wave heights, while the Kernel, GEV, and Logistic pdfs are observed to fit well. The study highlights that a constant power value in the Rayleigh distribution is not suitable for the region, as the power varies for different surf zones and spatially/temporally.

Summary: Microplastics are widely present in the marine environment and sediment is proposed to act as a final sink for marine microplastics. It was found that benthic invertebrates ingest microplastics and adverse effects may be observed upon ingestion. There is a major knowledge gap on the impacts of sediment-associated microplastics in marine, benthic invertebrates.

Summary: An experiment was conducted to measure the trajectories of 20 small objects in wave flume. The study found that gravel particles were only mobile within the swash zone, while microplastics moved onshore and accumulated in different zones. A tracking model was developed to predict the trajectories and potential applications for cleaning up microplastics on beaches.

Summary: A sediment bypass tunnel (SBT) is utilized to reduce reservoir sedimentation and restore river ecosystems by transporting sediment downstream. In this study, the benthic invertebrate community downstream of the Asahi Dam in Japan was analyzed to investigate long-term changes after the installation of the SBT. The study revealed that the SBT installation led to a significant increase in community similarity between upstream and downstream sites, indicating rapid recovery of the invertebrate community. However, the study also highlighted the need for additional measures to maintain habitat diversity and biodiversity in the long term, such as cobble augmentation and flow guiding structures.

Summary: This study investigated the fate and bioaccumulation of silver sulfide nanoparticles and silver nitrate in an aquatic ecosystem. The results showed that the silver from silver sulfide nanoparticles was less bioavailable compared to silver nitrate.

Summary: Shipwrecks are valuable historical resources and important biological habitats. This study investigated the impact of environmental and anthropogenic factors on shipwrecks in Stellwagen Bank National Marine Sanctuary. The results showed that shipwrecks hosted diverse invertebrate communities, with higher abundance on high-relief and overhanging substrata. The presence of entangled fishing gear negatively affected the species richness and community structure on shipwrecks.

Summary: The river-lake transitional zone is important for maintaining water quality in Lake Taihu. This study examined the water and sediment quality and benthic invertebrate communities in four regions of the transitional zone. The results showed spatial variations in the environment and invertebrate community, with pollution-tolerant species dominating the northern and western regions. Wind-wave actions in the southern region promoted photosynthetic activity and favored invertebrates that require well-aerated conditions. Brackish and saline environment-adapted invertebrates are suggested as indicators of a well-circulated and less eutrophic state in Lake Taihu.

Summary: Artificial reefs, such as shipwrecks, can mitigate impacts on natural hard bottoms, but unplanned ones may lead to negative effects. This study found that in exposed areas, benthic communities on shipwrecks were similar to those on nearby natural reefs, while communities in sheltered areas showed high dissimilarity.

Summary: This study aimed to assess the lethal and sublethal effects of diluted bitumens and conventional oil on freshwater benthic invertebrates. It found that dissolved hydrocarbons caused mortality in the organisms, but disappeared quickly from the water column. The sensitivity to different oil types varied among the two species, and the presence of natural sediment provided some protective role. The antioxidant enzymes measured did not appear to be relevant biomarkers for the exposure to diluted bitumen.

Summary: Roads form a global network of ecological barriers that have wide-ranging impacts on lotic ecosystems, including fragmentation, hydrological changes, sedimentation, and pollution. This study found that downstream of roads, there were lower densities of total macroinvertebrates and mayflies compared to upstream, while control streams did not show similar effects. Species density tended to be lower downstream, likely due to the lower macroinvertebrate densities at these sites. The species composition and abundances also differed between road impacted streams and control streams, suggesting a selection for different species in road impacted streams. Functional impacts included increased prevalence of predators in control streams and a higher proportion of grazers and shredders in road impacted streams.

Summary: This study examines fouling communities on different types of plastic debris in the Catalan Sea and characterizes the plastic type. The results show that plastic debris hosts diverse fouling communities, potentially due to the chemical structure and surface properties of the plastic. The presence of catshark egg cases suggests implications for their dispersal. Further studies at lower taxonomic levels are needed to detect new species introduction and potential invasive species associated with plastic debris.

Summary: Diluted bitumen (dilbit), an unconventional oil produced by the oil sands industry in Canada, has unknown effects on benthic organisms despite existing knowledge on hydrocarbon toxicity. The current provisional threshold values in Quebec for chronic and acute effects have not been tested for heavy unconventional oils like dilbit, indicating a need for further research.

Summary: This study analyzed 4837 surf zone injury (SZI) cases from 44 Goa beaches between 2008 and 2020. Calangute reported the highest percentage of SZIs at 24.63%, followed by Baga and Candolim in North Goa. For South Goa, Colva had the highest percentage of beach victims at 18.25%. The study highlights the importance of rescue and drowning data for beach management.

Summary: This study investigates the abundance and characteristics of microplastics (MPs) in benthic organisms from mangrove wetlands in Hainan, South China. The study finds that MPs are widely distributed among different species, with fibers being the most common type of MPs. The most dominant polymer found in the MPs is polypropylene. Crabs show a higher potential for accumulating MPs compared to other species.
