Release date- 19082019 - Bacteria found in muddy marshes, estuaries and coastal sediment
synthesise one of the Earth's most abundant climate cooling gases - according to new research from the University of East Anglia (UEA).
A clearer understanding of carbon burial in coastal regions will help improve the prediction of atmospheric carbon dioxide levels in the future, as carbon that is buried in coastal sediment
could become permanently trapped there rather than being released into the atmosphere where it can enhance warming.
Presence of pathogenic or potentially pathogenic bacterial strains like Bacillus subtilis, Escherichia coli, Klebsiella pneumonia, Micrococcus luteus, Providencia rettgeri, Pseudomonas aeruginosa, Salmonella enterica, Salmonella typhimurium, Shigella flexneri, Staphylococcus aureus and Staphylococcus epidermidis indicates microbial pollution of the coastal sediment
. Bacterial load reported in coastal sediment
of Uran is attributed to the coastal tourism, coastal dredging, excavation through mangroves for gas pipelines and erection of electricity poles, Container Freight Stations (CFS), road construction, inadequate sanitary facilities, open defecation and poverty among local community.
The experiment showed that, in just nine weeks, plastic bags smothered the surface of coastal sediment
, prevented oxygen and nutrient flow, and blocked light.

Just days after researchers announced the largest-ever recorded die-off of the Great Barrier Reef, a government report to UNESCO released Thursday noted that farm chemicals and coastal sediment
flowing into the waters were the biggest threats to the continued survival of the extensive ecosystem.
For example, a more refined sea-level record over millions of years is commercially interesting because it allows a better understanding of coastal sediment
sequences that are relevant to the petroleum industry.
Therefore, there has been a growing interest in the field of estuarine and coastal sediment
dynamics, including sediment transport, geomorphological process, and the transport of heavy metal by sediment particles [2, 3].
The Fe/Mn-bound metal species trend in this study area's coastal sediment
is presented in Figure 5.
Topics include the characteristics and behavior of waves, breakwaters, coastal sediment
transport, basic shore processes, modeling of coastal morphology, design concepts, and shore protection.
There is an abundant coastal sediment
supply being delivered from the erosion of a drowned delta to the north as well as sediment arriving from the south, transported from the Delaware River (McMaster, 1954; Dobday, 1981).
For example, California developed (1) the Coastal Sediment
Management Workgroup, which uses littoral cells (a complete cycle of sedimentation including sources, transport paths, and sinks) as the basis for evaluating and managing sediment transport issues; (4) (2) the Marine Life Protection Act Initiative, which uses a science-based regional approach to assess the adequacy of the existing array of marine protected areas; (5) and (3) the Southern California Wetlands Recovery Project for wetland restoration and management in the Southern California Bight.
