    <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>

    <p>The PRISME cruise objectives were to: - quantify the risk of earthquake-induced sedimentary liquefaction (for areas studied on the Algerian margin and slope off Nice, France); - quantify the risk of instability and failure due to loss of resistance in sensitive clay (slope off Nice); - quantify the risk of slope breaks and erosion caused by bottom currents (canyon heads - gulf of Lion); - identify the triggering factors for slides seen off Ibiza; - and begin to identify the turbidity related to seismic activity along the Algerian margin. This falls under the ANR-Isis an dGDR Marges projects. The cruise took place on 5 sites: Site 1A - Gulf of Lion - North: N 42° 50.00&apos; South: N 42° 40.00&apos; West: E 003° 35.00&apos; East: E 004° 0.00&apos; / Site 2B - Ibiza channel - North: N 38° 39.00&apos; South: N 38° 37.50&apos; West: E 000° 47.00&apos; East: E 000° 51.00&apos; / Site 3A - Alger - North: N 37° 30.00&apos; South: N 36° 40.00&apos; West: E 002° 00.00&apos; East: E 004° 00.00&apos; / Site 3B - Djijel North: N 37° 30.00&apos; South: N 37° 00.00&apos; West: E 005° 00.00&apos; East: E 004° 00.00&apos; / Site 4A - Djijel North: N 43° 40.00&apos; South: N 43° 38.00&apos; West: E 007° 12.00&apos; East: E 007° 15.00&apos;.</p>

    <p>?The cruise took place from 22 November to 20 December 2006 aboard RV L&apos;Atalante. Its objective was to study the formation of passive continental margins and a special sedimentary sequence which exists all over the Mediterranean. The result of national (IUEM Brest, Géosciences Azur, University of Lille, UPMC) and European (Universities of Lisbon and Bologna, GEOMAR and AWI) cooperation, directed by Ifremer, the cruise mobilized some twenty scientists for nearly one month. The related project is GDR Marges.</p>
