RG1 Cruise (29HE20030619) carried out on the Research Vessel Hespérides in 2003, The purpose of the Special Action is to identify and assess the geo-environmental risks in the sinking area of ​​the Prestige vessel, through the integrated study of morphology, stratigraphy and sedimentary facies, bottom types, tectonic structures, fluid migration, seismicity and physical properties. geochemical and geotechnical features that characterize the sediment of the bottom and sub-seabed; It also has the purpose of determining the possible contamination by the fuel of the sea bottom and sub-fund and the geochemical processes acting in said area in order to assess the environmental impact. Before the activity that is going to be carried out on the wrecks, a study like the present one is fundamental, which will allow to know the characteristics of the seabed that this activity has to support and the possible impact that can be exerted on the environment and the interaction resulting between the marine environment and the activity carried out. The institutions participating in the study are: Institute of Marine Sciences (ICM-CSIC), Marine Technology Unit (UTM-CSIC), University of Vigo, University of Cádiz, Geological and Mining Institute of Spain, University of Barcelona, ​​Institute of Sciences of the Earth Jaime Almera (ICTJA-CSIC) and Universidad Complutense de Madrid. The results of this study will be transferable in the short term to the sectors of Government, Industry, Civil Defense and Insurance Companies, to organize what are called prevention and preparation activities, and will help to establish the technical conditions to increase the safety of persons and civil works that may be affected by the Prestige ship spill. The work methodology consisted in the study of bathymetric data obtained with the multibeam probe system EM-12, profiles of high seismic (air cannons) and very high (TOPAS) resolution, and sediment cores of up to 4 m length obtained in three campaigns carried out aboard the ship Hespérides. Various analyzes have been carried out on the sediment samples and include the following types: granulometric analysis, analysis of sand fraction components, determination of carbonate content, X-ray analysis, analysis of physical properties (P waves, magnetic susceptibility, natural radioactivity). ), optical petrographic study -SEM, TEM, DRX-, elemental analysis, organic constituents and radiometric dates. Likewise, seismic networks were installed on land and sea. In the land campaigns (March to October) a terrestrial earthquake intervention network has been deployed in the NW Peninsular, in the area between Ferrol and Vila Nova de Gaia in Portugal. A total of 12 portable stations have been set up to supplement the registration stations with respect to the existing ones permanently, belonging to the national network operated by the National Geographic Institute. On the other hand, to control the local seismic activity around the Prestige, a network of 10 ocean-floor seismometers (OBS) was installed around the wrecks, which remained anchored for almost a month

MIXTO Cruise (29HE20160306) carried out on the Research Vessel Hespérides in 2016, The main objectives of this survey are: 1) Mapping sedimentary features resulting from the interaction of water bodies with gravitational features ( valleys and landslides ) from the upper slope 2) seismic analysis for the establishment of a model facies sedimentary 3) Determine the recent sedimentary processes. During the cruise, which in its data collection stage in the south of Buenos Aires completed 990 miles of navigation between 39 and 42 ° Lat. S, geomorphological and morphosedimentary features of the outer platform and slope at depths between 90 and 4000 meters were analyzed, sedimentary structures of the shallow subsoil (up to 100 m below the bottom) were analyzed, and recent processes related to the interaction between geological factors (transport of sediments, erosion-deposition processes on terraces and gravitational on slopes and underwater canyons) and oceanographic (interfaces between water masses, longitudinal currents to the margin and turbidity). The instruments used were: multi-beam echo sounder of shallow and deep water, parametric profiler TOPAS, 12 KHz echo sounder, biological echo sounder, XBT-XSV and Doppler ADCP

INCRISIS Cruise (29HE20160523) carried out on the Research Vessel Hespérides in 2016, On January 25, 2016 there was an earthquake of magnitude Mw = 6.3 with epicenter in the Alboran Sea (35.6ºN, 3.81ºW), which caused material damage in Melilla and Moroccan cities; It was also felt in the southeast of Iberia. It is the main earthquake of the seismic crisis that continues today. Its focal mechanism and the distribution of replicas suggest the activity of an unknown fault of direction NNE-SSO of about 25 km in length, in the western part of the Dorsal de Alboran. This seismic activity seems to be in continuity with the earthquakes of Alhucemas of 1994 and 2004, and associated with the prolongation of a fault zone in the rifeña mountain range. The realization of this marine geology cruise is a unique opportunity to know the effects that the seismicity of these characteristics causes in the bottom and sub-fund of the Alboran Sea, such as displacements of the seabed, triggering of landslides and other risks associated with them ( eg, tsunamis) that would affect both Moroccan and Spanish coastal areas. The results of this campaign will be analyzed in detail during the development of a new research project (DAMAGE) requested to the MINECO call and will contribute to characterize the geological hazard of active faults in the Alboran Sea. The specific objectives of this cruise include: 1) Cartography and characterization of sedimentary and tectonic features and comparison with the previous data 2) Stratigraphic analysis, simian facies and deformation structures 3) Determination of sedimentary and tectonic processes triggered by the earthquake and the seismic crisis
