The tropospheric burden of arsenic has been estimated from representative global surface concentrations and an small particle scale height 3.9 km to be ∼8×10 8 g As. Total atmospheric emissions both natural anthropogenic sources have 31×10 9 As/yr. On a basis the major source appears volatilization processes, appear volcanoes terrestrial biosphere. removal is 30–50×10 residence time about days.
Bottom trawling is a widespread fishing practice that has consistently been established to result in harmful, enduring effects including physical modification of the seafloor, and impacts on biogeochemical cycling as well benthic ecosystems. The mechanisms equipment used, such trawl doors, penetrate seafloor disturb sediment structure, resuspending particulate matter altering seafloor's organic composition morphology. Previous studies have assessed carbon storage marine sediments,...
Three samples of marine aerosols were collected from a 20 m high tower on the coast Bermuda using volume cascade impactor. The elements Na, Al, Fe, Mn, Sc, Th, and Co found primarily particles with aerodynamic equivalent radii approximately 1 µm or greater their source is likely either sea (Na) crustal weathering. However, Cu, Zn, As, Cd, Pb, Sb, Se, Hg are present in concentrations too to be explained by bulk seawater normal weathering source. major mass these less than µm;, suggesting that...
Globally, continental shelf environments, and the marine sediments therein, have been recognised as having significant roles to play in sequestration, cycling storage of. Recently, identified largest, but most uncertain, stock of carbon stored on shelf, citing a lack empirical data. Moreover, seabeds are coming under increased pressure through anthropogenic impacts, such offshore renewable energy development, trawling dredging, climate change effects. To fully understand, effectively manage...
Blue Carbon traditionally refers to carbon buried and stored in coastal or terrestrial environments such as mangrove forests seagrass meadows. However, marine sediments, like clays sands, found on continental shelves, are increasingly being recognised important settings included national management plans.  To fully understand the importance of its potential mitigate against climate change, a thorough understanding quantification is required. This performed through analysis sediment...
