<p>The purpose of WestMedFlux is to study thermal fields in ocean-continent transition zones in the Western Mediterranean, and the role of fluids and salt diapirs on the thermal field.</p>

<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 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 objectives of the DETSUFA cruise (BIO Hespérides 04/03–17/03/2013) are (1) to evaluate the footprint in the seafloor of a series of earthquake-generated subaerial landslides that took place in Fiordo de Aysén, Chile, in 2007, which entered the seawater generating a number of destructive tsunamis which killed 10 and produced significant damage in the local infrastructure, (2) to reconstruct the morphology and dynamics of these landslides in order to obtain input data for tsunami modelling, and (3) to determine the occurrence of similar episodes in the past that might have generated other tsunamis, in order to establish a possible recurrence period of such events. The cruise fits within the global scientific interest stirred up by tsunamis in general, being the Fiordo de Aysén a highly relevant analogue for the understanding of this kind of events occurring in semi-enclosed basins such as fjords, lakes or water dams, which often harbour large human population and infrastructures.

The scientific goal of the cruise is to improve our knowledge of the geodynamic evolution of the Gibraltar Arc System (GAS) from improving the existing dataset in particular margin segments of the westernmost Mediterranean. Particularly, the Miocene to Holocene tectonic evolution of the shallow crust, as determined by its deformation pattern, tectonic partitioning and kinematics, neotectonics and active tectonics. The survey was conducted in three different crustal scenarios: 1) a relatively thinned continental crust at the Palomares and Cartagena margins; 2) an anomalous or oceanic crust at the ocean-continent boundary located at the foot of theses margins, and to the east of the Alboran Basin; and 3) a highly fractured and sismogenic continental crust at the Alboran southern margin (Morocco Margin). The survey consisted in acquiring multichannel seismic profiles and concurrent, multibeam bathymetry, and magnetometer and gravimeter records.
