BUSCADOR RECOLECTA

Data base containing SPME-GC-MS raw analytical data obtained and used by Quintanilla-Casas et al. (Foods, 9: 1509). Data correspond to the volatile fingerprint of 305 authentic and traceable virgin olive oil samples produced in several EU and non-EU countries during two consecutive crop years (2016–2017 and 2017–2018), and to the information the olive oil category assigned by six official sensory panels in the framework of OLEUM project (EC H2020 Programme 2014–2020). TIC were extracted, aligned, and used to in-house validate the analytical fingerprint and to validate the screening tool to support virgin olive oil sensory panels. This screening tool was based on a PLS-DA classification approach to discriminate the virgin olive oil categories (extra virgin, virgin and lampante olive oil).

Data base containing SPME-GC-MS raw analytical data (total ion chromatograms, not aligned) obtained and used by Quintanilla-Casas et al. (Foods, 9: 1509). Data correspond to the volatile fingerprint of 305 authentic and traceable virgin olive oil samples produced in several EU and non-EU countries during two consecutive crop years (2016–2017 and 2017–2018), and to the information on the sensory attributes, defects and the olive oil category assigned by six official sensory panels in the framework of OLEUM project (EC H2020 Programme 2014–2020). Briefly, data correspond to SPME-GC-MS scan intensities of the total ion chromatogram at each retention time from 5.5 to 61.96 min. These data were aligned and used to in-house validate the analytical fingerprint and to validate the screening tool to support virgin olive oil sensory panels. This screening tool was a PLS-DA classification apporach to discriminate the virgin olive oil categories (extra virgin, virgin and lampante olive oil).

HITS Cruise (29HE20010907) carried out on the Research Vessel Hespérides in 2001, Characterization of tsunamigenic structures in SW Iberia margin by Side Sonar TOBI. High resoultion imaging of tsunamigenic Structures in the southwest Iberian margin (Hits). The HITS campaign has been designed to determine the detailed geometry of the active seismogenic structures of the South West of the Iberian Peninsula using the TOBI high resolution sonar. In addition, to calculate the style and movement of active faults, as well as recurrence rates, the sampling and subsequent dating of the units associated with the seismic cycle of the fault is necessary, for example the landslides located at the base of the escarpment. For this purpose, we forecast the realization of several gravity cores in areas previously identified by TOBI, corroborated by multibeam. echosounder and parametric probe. Finally, to determine the possible factors that may influence the nucleation and propagation of earthquake ruptures, we plan to investigate the thermal regime of the fault zone by means of the heat flow probe and its possible escape of fluids, by means of a nephelometer / underwater camera SHRIMP

IMPULS Cruise (29HE20060516) carried out on the Research Vessel Hespérides in 2006, South Iberian Margin Paleoseismological integrated stUdy of large active Structures (IMPULS). The IMPULS project is based on a multidisciplinary and integrated onshore-off shore neotectonic and paleoseismological study of the Carboneras Fault Zone (CFZ) at the SE margin of the Iberian Peninsula. In order to obtain the resolution required to study the vertical geometry of active faults in South Iberi-an Margin (e.g the Carboneras Fault) we tested a new high-resolution multi-channel seismic system onboard the RV Hespérides

SWIM Cruise (29HE20060531) carried out on the Research Vessel Hespérides in 2006, Earthquake and Tsunami Hazards in the Southwest Iberian Margin : High-resolution imaging of active faults and paleoseismic signature (SWIM) During June 2006 we carried out the ESF-EuroMargins SWIM marine geophysical cruise on board the Spanish RV Hespérides (PI. E. Gràcia) with the main objective to characterize the geometry, deep structure and timing of deformation of the active faults located at the westernmost Gulf of Cadiz (SW Iberian Margin). We acquired sixteen high-resolution multi-channel seismic (MCS) profiles together with Simrad EM120 swath-bathymetry and TOPAS sub-bottom profiler, totalizing more than 2700 km of data

EVENT-DEEP Cruise (29SG20100513) carried out on the Research Vessel Sarmiento de Gamboa in 2010, During the EVENT-DEEP survey (May 10th-June 7th 2010, research vessel B/O Sarmiento de Gamboa) the Yussuf Fault, located on the bisector of the Alboran Sea, and the Al-Hoceima Fault, located in the territorial waters of Morocco, have been investigated. Multibeam echosounder, high-resolution and high-penetration multichannel seismics, sub-bottom seismic profiling and gravity data have been acquired during the cruise. This new dataset will allow us to characterize the geometry of the faults and obtain earthquake recurrence intervals. In addition, images and samples of deep corals in the Bank of Chella and Alborán Ridge have also been acquired

TOPOMED-GASSIS_LEG1 Cruise (29SG20111003) carried out on the Research Vessel Sarmiento de Gamboa in 2011, The TOPOMED is a Collaborative Research Project is based in the characterization of the lithospheric structure of the Gibraltar Arc region, including the Gulf of Cadiz and Alboran Sea, and the syudy of the resulting effects in the relief. Within the TOPOMED national project, GASSIS (Gibraltar Arc System Seismic Investigations Survey) is the first of two cruises that will be carried out in the South Iberian Margin. The TOPOMED-GASSIS cruise has been has been successfully accomplished onboard the R/V Sarmiento de Gamboa, from the 3rd to the 17th October (Leg 1) leaded by E. Gràcia and R. Bartolomé (UTM-CSIC) and from 18th to 29th October (Leg 2) leaded by C.R. Ranero (ICREA/ICM-CSIC). In addition to the seismic imaging of active faults and large structures of the South Iberian Margins, the TOPOMED-GASSIS cruise also included the implementation of new cutting edge marine seismic instrumentation (> 3.7 km streamer). Thus, Leg 1 team departed from Vigo on the 27th September and tests along the Galician and Huelva coasts were carried out until the 2nd October included. The tests included the deployment and recovery operations of a 5.3 km streamer and one seismic array of > 3000 c.i. Two test lines were shot and quality control was carried out by the Leg 1 scientific party. Failures detected (i.e. low winch speed and problems with the winch break) were solved on board before the start of the cruise with the help of a specialized engineer who embarked for a day. The main aim of the cruise is to characterize the crustal and upper mantle structure of the South Iberian Margin. We focused on: a) the investigation of shallow processes (i.e. active faults, fluid venting, mass fluxes) and b) the imaging and characterization of the deep crustal and mantle structure of the area. These objectives could only be achieved by using the acoustic and new MCS instrumentation of the Spanish RV Sarmiento de Gamboa, which has provided unprecedented quality of data in the region. The data will permit to efficiently attenuate the seafloor multiple energy, and to use state of the art processing and imaging techniques to obtain the deep tectonic structure of the margin. To accomplish this goal we have used up to two high volume G-gun arrays and up to 6 km long Sercel multichannel digital streamer (480 channels) towed behind the vessel at a survey speed of 4.5-5 knots. Simultaneously to the seismic survey, we have used the hull mounted swath-bathymetry system to map unsurveyed areas, the hull mounted sub-bottom profiler Parasound to image the shallow sediments 0-100 m below the seafloor, a hull-mounted gravimeter and a shallowtowed magnetometer

SHAKE Cruise (29SG20150423) carried out on the Research Vessel Sarmiento de Gamboa in 2015, The SHAKE cruise consists in a 30-day in situ investigation using underwater vehicles (AUV and ROV) to survey the active seismogenic faults of the Eastern Alboran Sea (Carboneras Fault, N-S Fault system, Al Idrissi Fault and Yusuf Fault), located at the SE Iberian and NE Moroccan margins. These fault systems have been well characterized (i.e. geometry and kinematics, seismostratigraphy, seismic potential) during previous national and European projects. In the frame of the ongoing Spanish project SHAKE we have been allocated shiptime onboard the Spanish RV “Sarmiento de Gamboa” (SdG) to carry out a in situ marine paleoseismic investigation of active faults and its associated processes. The first part of the cruise (Leg 1: 23 April-13 May; 21 days) will be devoted to acoustic seafloor investigation (i.e. micro-bathymetry, sub-bottom profiler) to search for surface ruptures and on-fault / near-fault co-seismic seafloor deformation using the AUVs “AsterX” and “IdefX” (IFREMER, France) obtained in the frame of an OFEG exchange collaboration. The second part of the cruise (Leg 2: 16 May to 22 May, 7 days), will be devoted to a direct visual seafloor exploration and sampling of selected sites (i.e. scarps related to earthquake ruptures, fluid venting and associated habitats) using the ROV “Max Rover” (HCMR, Greece) in the frame of the IRIS project granted in EuroFleets-2

INSIGHT_LEG1 Cruise (29SG20180429) carried out on the Research Vessel Sarmiento de Gamboa in 2018, ImagiNg large SeismogenIc and tsunamiGenic structures of the Gulf of Cadiz with ultra-Highresolution Technologies. The general objective of the INSIGHT-Leg 1 cruise is to image and characterize, with the highest possible resolution, selected active seismogenic faults, large slope failures and investigate their relation with fluid seepage (mud volcanoes and salt diapirs) in the Gulf of Cadiz. The large-scale features of most of these elements, such as fault systems and slope failures have been previously mapped and characterized during recent projects. These structures may also represent a seismic and tsunamigenic hazard for the surrounding coasts of South Iberia and North Africa. The aims of the cruise are twofold: a) To characterize at the highest resolution selected active seismogenic faults located in the Gulf of Cadiz, such as the Marques de Pombal Thrust-fault, and the Lineament South characterized by the presence of fluid seepage to the seafloor (i.e. active mud volcanoes); b) To image with unprecedented resolution the seismic structure of mass movements often associated to active faults and presence of active fluid seepage, such as the Marques de Pombal slide-complex, the Ginsburg mud volcano and the Lolita salt diapir. We have been allocated 15 days of shiptime in April-May 2018 on board the Spanish RV “Sarmiento de Gamboa” to carry out a first ultra-high-resolution study of active faults and slope failures in the Gulf of Cadiz. We used the Autonomous Underwater Vehicle “Abyss” from GEOMAR-Kiel (Germany) and a 2D-high-resolution seismic system, composed of a 450 m long streamer and a 930 c.i. airgun array. During the cruise, we also acquired swath-bathymetry, parametric sub-bottom profiler and sediment sampling (coring)
