BUSCADOR RECOLECTA

Data base containing SPME-GC-MS raw analytical data obtained and used by Quintanilla-Casas et al. (Food Chemistry, 2020, 125556). Data correspond to 82 authentic and traceable olive oil samples, declared as EVOO by the suppliers obtained in the framework of OLEUM project (EC H2020 Programme 2014–2020) from seven different EU and non-EU countries: Croatia (n=11); Slovenia (SVN) (n=8); Spain (ESP) (n=17); Italy (ITA) (n=15); Greece (GRC) (n=6); Morocco (MAR) (n=15) and Turkey (TUR) (n=10). With the aim of reflecting the real production scenario, EVOO samples in this prospective study were obtained under usual production practices for commercial purposes, and thus consisted of both monovarietal oils as well as market blends of olive cultivars typical of each geographical origin. Briefly, data correspond to SPME-GC-MS scan intensities of the specific sesquiterpene hydrocarbon (SH) ions (m/z 93, 107, 119, 135, 157, 159, 161, 189 and 204) obtained from the Total Ion Current (TIC) between the 18th to the 30th minute. Thus, 2467 scans were obtained for each m/z ion implying 22203 variables per sample.

Data base containing data on the triacylclgyerol profile of genuine and adulterated olive oils obtained by Flow Injection Analysis-Heated Electrospray Ionisation-High Resolution Mass Spectrometry (FIA-HESI-HRMS). Data (total ion chromatograms) were obtained and used by Quintanilla-Casas et al. (Food Control, 2021, 123: 107851). Data correspond to relative abundances obtained for each mass signal that agreed with single positive charged sodium molecular ions and that could match with a triacylglycerol elemental formula (mass tolerance error set at 5ppm; molecular formulae calculation performed with Xcalibur 4.1. (Thermo Fisher Scientific, Bremen, Germany). This data base includes samples used in the study that were obtained by the OLEUM consortium. Samples included genuine olive oils, as well as Taylor-made adulterations blending genuine olive oils with other vegetable oils as adulterants (sunflower oli; soy oil; high oleic sunflower oil; avocado oil (refined and virgin); hazelnut oil (refined and virgin)). Blind samples are also included in the data base. Partial Least Squares-Discriminant Analysis (PLS-DA) was applied to these data to develop two independent binary models that discriminated between (i) genuine oils and blends with ≥2% of HL adulterants, and (ii) genuine oils and blends with ≥5% of HO adulterants, as described in Quintanilla-Casas et al., 2021.

Dataset containing SPME-GC-MS raw analytical data (total ion chromatograms, not aligned) obtained and used by Quintanilla-Casas et al. (LWT - Food Science and Technology 121: 108936). Data correspond to the volatile fingerprint of 174 authentic and traceable virgin olive oil samples previously graded by six official sensory panels (data from 2 outlier samples are not included) 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 under a fingerprinting approach by Quintanilla-Casas et al. to develop a classification model (PLS-DA approach) to verify the sensory quality of virgin olive oils, and it was suggested as an instrumental method to support sensory panels.

FAX Cruise (29HE19990801) carried out on the Research Vessel Hespérides in 1999, Filament and Fluxes (CANIGO). The campaign was carried out in Canarian waters, the main objective was the estimation of the flows of heat, water, salts nutrient and organic material in a filament of the upwelling of Northwest Africa, and to determine the effect of this transport towards oligotrophic waters on the metabolic balance of carbon in the planktonic communities of the Canary region. The specific objectives of the campaign were: 1) Determine the variability and bidimensional structure of the surface fields of temperature, heat of the ocean, nutrients, inorganic carbon and currents, in relation to the filament, during the study period. 2) Determine the three-dimensional structure and field of currents in the upper 300 m of the filament, in order to determine the origin and dynamics of the filament waters. 3) Determine the flow of particulate and dissolved organic matter exported by the filaments from the upwelling to the oceanic waters. 4) Determine the spatial variability of phytoplanktonic phytosynthetic parameters, pigment concentrations and spectral quality of light in the filament region, to allow the development of primary production models on a regional scale. 5) Determine the metabolic balance of microbial communities (community production and respiration) in the transition zone from eutrophic waters to oligotrophic open waters. 6) Observe the langranian displacement field of a body of water along the "jet" of the filament, by means of drifting Argos buoys. 7) Study the evolution of the stratification, vertical shear, concentration of nutrients, productivity and bio-optical parameters in the upper 200 m of the water column, near a drifting buoy that runs along the "jet" of the filament

PUMP Cruise (29HE20140831) carried out on the Research Vessel Hespérides in 2014, Study of the Vertical Oceanic Pump in mesoscale eddies (PUMP). This project will study the dynamics/kinematics of the ageostrophic secondary circulation (ASC) and mixing in surface mesoscale anticyclonic eddies and how they modulate plankton activity, plankton community structure, and accumulation and downward transport of organic matter (the Vertical Oceanic Pump, VOP). For this purpose we will conduct a novel interdisciplinary sampling strategy to survey an anticyclonic eddy from a Lagrangian perspective with a resolution down to the submesoscale range using cutting-edge instrumentation and methodologies. We will pay particular attention to the control of the ASC by eddy/wind interaction, by mixing, and by current/wind interaction and frontogenesis/frontolysis at its periphery. ASC will be diagnosed from trajectories of drifters drogued at the Ekman layer and at the eddy´s interior and using an omega-type equation that will include direct measurements of mixing/turbulence. Mixing regime, dynamic stability and vertical diffusion of tracers will be observed and derived from direct measurement of mixing/turbulence. Near-inertial waves trapping and its role in driving shear mixing will be studied from drifter trajectories and from the vertical variability of the horizontal velocity field. To establish the dynamics that forces the VOP we will also develop processes-oriented models and implement regional physical and physical-biogeochemical models for the Canary Region. We will also take advantage of the exceptional source of tracer provided by the El Hierro Island submarine volcanic eruption for the study of eddy submesoscale spatial-temporal variability, combining satellite images and modeling. Finally the physical and biogeochemical observations and processes will be combined and correlated to derive a conceptual model of the dynamics of the marine system linked to the VOP in mesoscale eddies
