BUSCADOR RECOLECTA

SAGAS-BIS Cruise (29SG20100609) carried out on the Research Vessel Sarmiento de Gamboa in 2010, The Gibraltar Arc System: Geodynamic Processes in the South Margin. The SAGASbis project intends to study, through a multidisciplinary geological and geophysical approach, the recent evolution of the Spanish margin and the Alborán Sea basins, with the aim of 1) better understanding the dynamics of the external processes responsible for morphology and sedimentation in the South-Iberian continental margins 2) analyze the interrelation between deep and superficial processes 3) determine the stratigraphic architecture in adjacent margin and basin segments and 4) characterize submarine and paleoseismic morphologies, paying special attention to turbiditic and instability systems Plio-Quaternary sedimentary. The area under study is located in a region where there are considerable earthquakes and underwater landslides, which is why this project is of great interest in order to design preventive actions and contingency plans for geological and environmental risks. At the same time, the exploration of this area will serve to detect the presence of hydrocarbons. This project has carried out a geological campaign aimed at the acquisition of acoustic and seismic data from the seabed and the collection of sediment cores

IDEADOS-10 Cruise (29SG20100712) carried out on the Research Vessel Sarmiento de Gamboa in 2010, Benthopelagic ecosystem structure in the western Mediterranean: a multidisciplinary approach and different time scales in the Balearic Islands.The overall objective is to determine relationships between environmental conditions and nekto-benthic slope communities in two areas of the western Mediterranean, with distinct geomorphologic and hydrodynamic characteristics. Sub- Objectives 1.To determine the effect that seasonal variability of the hydrodynamics has on the species and communities of the slope and on their trophic resources along the water column, by means of the study of the various compartments of the zooplankton (micro-, meso- and macro-zooplankton) and nekton (micro- and macro-nekton). 2. To determine the viability of applying acoustic methods for the characterization of the communities in the Deep Scattering Layers (DSL) of the meso-pelagic domain.3. To determine the influence of the high frequency variability (daily, fortnightly and/or monthly) of the oceanographic conditions on the biology and dynamics of the red shrimp. 4. To contextualize the oligotrophic ecosystems of the Balearic Islands from a global perspective, including adjacent areas of western Mediterranean, from: (i) the estimation of the degree of connectivity between populations of the continental margin of the north-western Mediterranean and the Balearic Islands, using geochemical markers in hake otoliths; and, (ii) the analysis of information from fishing exploitation on the peninsular coast and the archipelago
