<p>The deep basin and continental shelf of the Gulf of Lion (North Western Mediterranean) are known for the formation of dense water in wintertime by the action of N-NW continental winds. This dense water is formed both offshore and at the coast. The area of Cap de Creus and its adjacent canyon is the main zone where dense coastal water is exported. Dense water dynamics on the continental shelf are also influenced by E-SE storms. Transfers of organic, inorganic, particulate and dissolved matter from the surface to the deep basin and from the shelf towards the slope by these physical processes can influence the redistribution of chemical elements in sediments, as well as the structure and functioning of benthic and pelagic ecosystems. The CASCADE cruise aimed to determine the characteristics of these two physical mechanisms and their numerous impacts, as well as monitoring changes in the hydrology, dynamics, sedimentology and biogeochemistry of water bodies. We propose a qualitative and quantitative estimate of particulate and dissolved, organic and inorganic matter fluxes exported towards the slope and the deep basin by these mechanisms.</p>

They focus on the seabed research of Mediterranean sea (Spain ), both indirect and direct. Carry out a survey of the fishing beaches to later elaborate fishing charts. Systematic bathymetric survey of the study areas with 100% coating (Multi-beam echo sounder EM-300). seismic profiles according to the ship's defeat (Topas 710 system). Performance of sound velocity profiles in the water column. Side sweep sonar in selected areas. Sediment sampling (Shipeck dredges - Box corer). Sampling of Rocky Outcrops (Rock Dredge).
