Evaluate transport of water salinity, temperature, carbon and other variables of the greenhouse

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.

Analyze and evaluate the environmental impact on the coastal area of Gibraltar caused by the dumping of concrete and rock blocks into the sea.

Impact of exploitation of mineral resources on the deep-sea ecosystems (MIDAS project)

The main objetive of PLOCAN1310 cruise is twofold. On the one hand implement PLOCAN testing bank area, located in NE coast of Gran Canaria island, and on the other hand, doing seasonal sampling of ESTOC (Estacion de Series Temporales Oceánias de Canarias), which represents PLOCAN node oceanic observatory, located 60 nautical miles north of Gran Canaria island. Hydrological and Geophisical sampling at NER300 area.

Background and Aims MEDWAVES The Strait of Gibraltar (SG) and the surrounding areas, Gulf of Cadiz (GoC) in the Atlantic, and Alboran sea (AS) in the Mediterranean, are key areas to understand the distribution and connectivity of marine communities (Patarnello et al. 2007), as the SG and the encounter of water masses at the Almeria Oran front represent an oceanographic transition area, connecting the Atlantic Ocean and the Mediterranean Sea (Lacombe & Richez 1982). The Mediterranean water flows out from Gibraltar (MOW), extends towards the East of the Atlantic, building a warm and salty water mass which propagates in North West direction from Portugal originating the “Mediterranean Water“ (MW) in the Atlantic. This warm and salty water mass becomes characteristic of the North Atlantic in mid waters (around 1100 m) (Candela 2001). The occurrence of cold-water coral (CWC) communities in the NE Atlantic has been related to the pathway of the MOW, whereby this current system would have an historical influence on the migration of coral larvae and (re)colonization of the Atlantic in the post-glacial era (De Mol et al. 2005, Henry et al. 2014). The MEDWAVES (MEDiterranean out flow WAter and Vulnerable EcosystemS) cruise target areas under the potential influence of the MOW within the Mediterranean and Atlantic realms. These include seamounts where CWC have been reported but that are still poorly known, and which may act as essential “stepping stones” connecting fauna of seamounts in the Mediterranean with those of the continental shelf of Portugal, the Azores and the Mid-Atlantic Ridge. During MEDWAVES sampling will be conducted through two of the case studies of ATLAS: Case study 7 (Gulf of Cadiz-Strait of Gibraltar-Alboran Sea) and Case study 8 (Azores). The main goals of the cruise are: (1) to characterize physically and biogeochemically the MOW Path and understand its interaction with the general Atlantic Meridional Overturning Circulation (AMOC) stream, from the Alboran Sea to the Azores, through the Gulf of Cadiz, and the Ormonde Seamount (see map), exploring the relationship between the oceanographic settings of these target areas and the ecosystems therein (ATLAS WP1 and WP3) and (2) to characterize communities associated to the transition area, and sample for population genetic analysis aiming at understanding the way the populations located in the target areas contribute or have contributed to connectivity between the Mediterranean Sea and the Atlantic Ocean (ATLAS WP3 and WP4). Results gathered during the cruise will also contribute later to feed other ATLAS WPs. The activities planned to achieve these aims are presented in the brief description of the work program of the different research teams participating in ATLAS (Work program of the research teams).
