Summary: Morpho-bathymetric data analysis in the Gulf of Naples provides new geological evidence and construction of digital elevation models and thematic maps, helping to identify potential landslide-prone areas and understand the structural characteristics of the seabed. These findings contribute to the planning and management of coastal zones in the Naples Bay.

Summary: To differentiate the causes of aged organic carbon (OC) in sediments, we propose a mathematical index, b(AgedOC), and apply it to terrestrial OC transport and dispersal pathways and other continental margin settings. This method helps us understand the contribution of lateral transport to the aging of OC in marine sediments.

Summary: This study focuses on geoid determination in Northern Europe and finds that considering bathymetry can greatly influence the modeling results, particularly in the rugged coastal areas of Norway. Additionally, the use of shipborne GNSS and airborne laser scanning can effectively validate the modeling results.

Summary: According to the Natura 2000 Network, various studies have been conducted to assess the importance of new marine protected areas. One of these studies examines the Capbreton Submarine Canyon System located in the Bay of Biscay. Through surveys and data analysis, researchers were able to characterize the morphosedimentary features of the canyon system and identify the presence of a large pockmark field.

Summary: This study introduces a new method for monitoring shallow bathymetry changes using drone multispectral imagery. The results show good correlation and low errors with sonar measurements, and assist in identifying different morphobathymetric features. The temporal data reveal important erosional and depositional patterns, and show a migration trend in the shallow bathymetry over a 5-month period. Drone-based multispectral imagery proves to be an important and cost-effective tool for shallow seafloor mapping and monitoring when combined with shallow water analytical models.

Summary: About 15 Tg of plastic enter the ocean each year, with the majority accumulating in marine sediments rather than floating on the surface. From 1950 to 2010, an estimated 170 Tg (25-900 Tg) of nonfibrous plastic has accumulated in marine sediments globally, confirming their role as a major sink for plastic.

Summary: The study found that multiple low-abundance archaeal groups are actually catabolic protein degraders, while the functional role of widespread extracellular peptidases is not an optimal tool to identify protein catabolism. In addition, the catabolic degradation of sedimentary protein is not a common feature of the abundant archaeal community in temperate and permanently cold marine sediments.

Summary: A novel thermoanalytical method for quantifying microplastics by measuring the contents of microplastic-derived carbon has been proposed in this study, which effectively eliminates the limitation of particle appearances. Case study demonstrates the high reliability and practicability of this method in quantifying microplastics.

Summary: The study found that specific members of bacterial communities thrive under increasing levels of persistent organic pollutants (POPs) in marine sediments, and that the abundances of certain taxa correlate with specific POPs (or groups), which could potentially be employed in monitoring, status assessment and environmental management purposes.

Summary: This study conducted the first Canadian Arctic-wide investigation of anthropogenic particles in marine sediments, revealing that microfibers and microplastics, with a significant portion being anthropogenic cellulose fibers, are the main components. Concentrations of these particles in Canadian Arctic sediments exceeded those in urban areas near point sources of plastic pollution.

Summary: This study analyzed the pollution of marine sediments in a large number of locations on the south coast of Mallorca island. The results showed that the concentrations of heavy metals exceeded the limits for uncontaminated sediments, especially near the outfalls. The study also found that marine sediments can be a useful indicator of the impact of anthropogenic activities on the environment and human health.

Summary: Coastal areas pose challenges for collecting consistent, high-resolution bathymetric data, but phase-measuring sidescan sonars offer a solution particularly in shallow waters. These instruments provide large effective swath widths and are ideal for shallow water mapping operations, despite requiring higher levels of noise and processing compared to multibeam data. The co-location of sidescan backscatter and bathymetric data allows for unique uses and analyses not feasible with other data sets.

Summary: Hydrocarbons have significant impacts on marine ecosystems, particularly on the diversity and abundance of sediment macrofaunal communities. Diesel fuel has the largest initial impact on communities, but its effects diminish over time, while lubrication oils have long-lasting effects. Different types of hydrocarbon products also have different effects on the response and recovery of benthic animals.

Summary: With ongoing climate change, research into the biological changes occurring in vulnerable ecosystems, such as Antarctica, is critical. In the Totten Glacier region of Sabrina Coast, there are significant differences in the bacterial and eukaryote composition between the water column and sediments. The study provides the first assessment of DNA transfer from ocean waters to sediments and an overview of the microscopic communities occurring in the climatically important Totten Glacier region.

Summary: This study investigated the presence of contaminants in marine sediments near Casey Station in East Antarctica and found higher concentrations of most contaminants at disturbed locations. The spatial distribution of sediment properties and contaminants displayed intricate patterns of variation. Some contaminants exceeded international guidelines for sediment quality. The study concluded that Antarctic research stations may pose a moderate level of long-term ecological risk to local marine ecosystems, and raised awareness and monitoring programs are recommended.
