<p>Technical trials for NAUTILE, SYSIF, SMF RESON, GAPS and MATS equipment. The trials cruise had 2 legs: Leg 1 from 04/05/09 to 15/05/09 (Brest - La Coruna) and Leg 2 from 16/05/09 to 19/05/09 (La Coruna - Funchal).</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' South: N 42° 40.00' West: E 003° 35.00' East: E 004° 0.00' / Site 2B - Ibiza channel - North: N 38° 39.00' South: N 38° 37.50' West: E 000° 47.00' East: E 000° 51.00' / Site 3A - Alger - North: N 37° 30.00' South: N 36° 40.00' West: E 002° 00.00' East: E 004° 00.00' / Site 3B - Djijel North: N 37° 30.00' South: N 37° 00.00' West: E 005° 00.00' East: E 004° 00.00' / Site 4A - Djijel North: N 43° 40.00' South: N 43° 38.00' West: E 007° 12.00' East: E 007° 15.00'.</p>

<p>?The cruise took place from 22 November to 20 December 2006 aboard RV L'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>
