The effects of massive dumping of dredged material were studied during and after the last large Barcelona port expansion. A benthic tripod equipped with a current meter, a turbidimeter and a video camera was deployed at the edge of the Barcelona shelf dumpsite. Additionally, sediment cores were taken before, during and after dumping at the tripod l...
Article
Continental margins are transitional areas between the land and the deep ocean where large amounts of particulate matter are supplied, transported, and ultimately deposited in the deep sea. High-energy hydrodynamic processes such as storms, ocean currents, or internal waves and tides, as well as bottom trawling activities contribute to the resuspen...
Article
Submarine canyons are preferential pathways for transport of particulate matter and contaminants from the shelf to the deep sea. The Gulf of Palermo continental margin has a very narrow shelf (about 2–3 km wide on average) and is incised by several submarine canyons that favour shelf-slope sediment transfer. A sediment core collected on the outer s...
