Understanding the role played by the combined physical-biogeochemical dynamics at (sub)-mesoscales in exchanges of matter and energy between coastal and open sea areas. The LATEX strategy is based on selective and combined use of numerical modelling and in situ observations (Lagrangian floats, SF6, shipboard ADCPs, ADCP moorings, satellite images, gliders and coastal radars). The main objective of LATEX is to study the impact of an eddy structure at (sub)mesoscale, which is chronically present in the western part of the Gulf of Lion, in interaction with the North Mediterranean current(NMC)on trends in the distribution of conservative tracers and biogeochemical properties. Thanks to this strategy, LATEX should provide answers to the following questions: - Is this type of structure likely to significantly affect the horizontal transfer of matter between the continental shelf and the NMC? - What are the consequences for biogeochemical cycles of the structure's interaction with the NMC? - How do CO2 concentrations evolve within the eddy throughout its life cycle? - How does this type of (sub)-mesoscale coastal eddy act in structuring of plankton communities and the variability in primary production observed in the study zone? - Are the amounts of matter transferred by (sub)-mesoscale structures significant with respect to that displaced by the general circulation on seasonal and annual scales? The related project is called LATEX (LAgrangian Transport Experiment).

<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>

The objective of the NUREIEVA-3D campaign is the acquisition of a high-resolution 3D seismic cube of the submarine extension of the Portmán Bay mining spill deposit, in the vicinity of Cartagena, Murcia province, in order to establish the geometry and three-dimensional internal structure of said reservoir. To carry out the campaign, it will be necessary to install, test and deploy from the ship a complete 3D seismic system that will be provided by the subcontracted company GeoSurveys
