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
