BUSCADOR RECOLECTA

GEBRA Cruise (29HE19931203) carried out on the Research Vessel Hespérides in 1993, Geological evolution of the Bransfield Basin and the South Scotia Sea Ridge. Work has been carried out with multibeam, single-channel reflection seismic, parametric BPS probe, magnetometry, gravity cores extraction and instrument anchoring. These techniques have allowed to characterize in great detail the morphostructure, the sedimentary coating and the magnetic anomalies of the studied area

BIG-95 Cruise (29HE19950515) carried out on the Research Vessel Hespérides in 1995, Characterisation of the recent BIG'95 debris flow deposit on the Ebro margin

GEBRAP Cruise (29HE19961203) carried out on the Research Vessel Hespérides in 1996, Geological evolution of the Pacific margin of West Antarctica: Seafloor spreading and Plate Tectonics. Objectives of the campaign: 1) Morphostructural study of the sectors of the Bransfield Basin, and surroundings, not previously investigated by means equivalent to those that equip the BIO Hesperides, with special attention to submarine volcanism and its relationship with the segmentation and evolution of geodynamics of the basin. 2) Morphostructural investigation of the collision between the extinct dorsal of the Drake's Plate and the South Shetland Trench, and between the trench and the main fracture zones. 3) Contribution of new elements for the knowledge of the evolution of the Pacific margin of the Antarctic Peninsula in its structural, sedimentary, and chronological components. 4) Detailed analysis of the morphology and internal structure of the sedimentary bodies and erosive forms of the Pacific margin of the Antarctic Peninsula, in the northern Bellinghausen Sea. 5) Contribution to the improvement of seismic stratigraphy models in glacial-marine contexts. 6) Characterization of the petrology and the age of the volcanic buildings of the Bransfield Basin. 7) Determination of detail morphology and sedimentary fill along the axis of Gerlache Strait. 8) Investigation of the morphology of detail, the structure and sedimentary coating on the continental shelf of the King Jorge Island. 9) Study of deep-seated benthic organisms. 10) Estimation of krill biomass

MARINADA Cruise (29HE20020803) carried out on the Research Vessel Hespérides in 2002, Continental Slope Stability (COSTA-ETC) .The main objective of COSTA is to assess the stability of the European continental slope in relation both to the natural processes that occur in the slope and to the effects of human activities (for example the extraction of hydrocarbons in deep waters). This objective will be achieved through rigorous analysis of 1) landslides that have occurred from prehistory to the present. 2) areas conducive to sliding. 3) areas of interest for deepwater oil and gas exploration

EUROLEON Cruise (29HE20071006) carried out on the Research Vessel Hespérides in 2007, Study the relationships between the current morphology of the seabed, the sedimentary coating and the transport processes of active and past sediments. Integrated analysis of the sedimentary drainage systems of the continental margin, incorporating a "seascape" modeling component that includes the most determining control factors and the development rates of the morphosedimentary elements that make up the margin and the deep basin.The ROV transects were predefined from multibeam bathymetry in a seamount area in October 2007 during the ‘EUROLEON’ cruise on board R/V Hespérides, along the Iberian margin of the Valencia Trough. A video survey was performed with a ROV (Max Rover Mark II) equipped with two video cameras and with zoom (central and lateral view) and 6 light focus. The dive was conducted between 460 and 800 m depth. Videos were analyzed in real time onboard and observed animals were identified up to the possible minimum taxonomical level

HERMES Cruise (29HE20090915) carried out on the Research Vessel Hespérides in 2009, Hotspot Ecosystem research on the Margins of European Seas (HERMES). Further multibeam surveying was completed and improved the resultion in an area where cold-water-coral ocurrences have been reported

PROMARES Cruise (29SG20110630) carried out on the Research Vessel Sarmiento de Gamboa in 2011, The PROMARES-OASIS DEL MAR cruise will focus on identification operations, underwater cartography and analysis of the nature of the seabed, and will study the sedimentary structures, the benthic communities and the impact of human activity on the submarine canyons and the slope of the continental margin of the Catalan coast, especially the submarine canyons of Cape Creus, Palamós and Blanes. Will study the different dynamic processes that take place in the submarine canyons and adjacent slopes, especially the phenomena linked to extreme storms and the cascading processes of dense platform waters in the north-western Mediterranean, up to 2,000 meters deep. Is the first scientific campaign of the Liropus 2000 (with aticulated arm to take samples, It can also absorb sediment with suction pumps ), a remote controlled scientific submarine vehicle (remotely operated vehicle, ROV) of the IEO

MATER-4 Cruise (29GD19970603) carried out on the Research Vessel García del Cid in 1997, Collection and reinstallation of the anchored line( equipped with Technicap PPs3/3 and Aanderaa currentmeters) in November 1996 at North of the Balearic Islands

MATER-6 Cruise (29GD19971101) carried out on the Research Vessel García del Cid in 1997, Study the mass transfer and ecosystem response, recovery of moorings and anchoring of mooring

PROMETEO-1 Cruise (29GD20080929) carried out on the Research Vessel García del Cid in 2008, Integrated Study of deep Canyons and Slopes of the Western MEDITERRANEAN: an essential habitat.To investigate the impact on the bathyal populations of meio-, macro- and megafauna, and in particular on the deep red shrimp Aristeus antennatus, of the events of massive transport of sediment and fresh organic matter towards the deep margin and basin associated to cold water cascading from the shelf, the implications of which have recently been described by Canals et al. (Nov. 2006) in Nature.The combination of abiotic and biotic factors make the canyons and deep slopes of the Western Mediterranean essential habitats in which occur well structured communities characterized by a clear faunal zonation and trophic web of low energetic level. This fragile equilibrium is highly vulnerable to anthropogenic and natural perturbations (Canal et al, 2006) focused by the submarine canyons.The investigated area has been the submarine Blanes Canyon.The sampling of benthic megafauna was carried out with both an Otter-Trawl Maireta System (OTMS) and an Agassiz trawl, over the same trawling lanes.Physical oceanographic data were obtained six mooring lines were deployed between 900 and 1500 m of water depth from November 2008 to November 2009 inside the Blanes Canyon and on the adjacent open slope to the south. Each mooring line was equipped with a Technicap PPS3/3 sequential sediment trap and an Aanderaa RCM-8/9 current meter placed 30 m above the bottom Temperature and salinity data were sampled using CTD SBE 911 casts performed over the mooring sites during the different oceanographic cruises
