The dataset is freely available on the web repository of the Spanish National Research Council (CSIC). There are 6 files in NetCDF format: 3 with precipitation estimations (pcp_) and 3 with standard errors (err_) of each estimation. Each of 3 files represent peninsular Spain (pen_), Balearic islands (bal_) and Canary islands (can_)., Spanish PREcipitation At Daily scale (SPREAD) is a new daily gridded precipitation dataset for Spain. It covers the whole territory of peninsular Spain and Balearic and Canary Islands at a 5x5 kilometre spatial resolution. Daily precipitation was estimated for each point of the grid from 1950-01-01 to 2012-12-31 in peninsular Spain and from 1971-01-01 to 2012-12-31 in the Balearic and Canary Islands. The grid was built using a previously reconstructed station-based dataset using reddPrec package (https://cran.r-project.org/web/packages/reddPrec). The observed precipitation information comprised 12,858 stations provided by Spanish Meteorological Agency (AEMET); Ministry of Agriculture and Environment (MAGRAMA); Meteorologic Service of Catalonia (METEOCAT); Navarra Government and several hydrological confederations., This study was supported by research projects CGL2015-69985-R and CGL2014-52135-C3-1-R, funded by the Spanish Ministerio de Economía y Competitividad (MINECO) and FEDER-ERDF funds.

SPA Adición de enmiendas a suelos contaminados.-- Información introducida en la base de datos WOCAT es una red global de gestión sostenible de tierras (SLM) que promueve la documentación, el intercambio y el uso del conocimiento para apoyar la adaptación, la innovación y la toma de decisiones en SLM.- El documento completo se puede ver y descargar en https://qcat.wocat.net/en/wocat/technologies/view/technologies_1273/, La enmiendas en suelos contaminados son aplicadas para disminuir la solubilidad y la biodisponibilidad de los nutrientes y microelementos en los suelos. Las enmiendas más comúnmente utilizadas a tal efecto son materiales calizos, fosfatos, óxidos de Fe y Mn, materiales orgánicos, aluminosilicatos, etc. El tipo y la cantidad de enmienda a aplicar depende de las características del sitio (suelo, hidrogeología, pendiente, clima, etc.), de la naturaleza del contaminante y del uso del suelo. La aplicación al suelo de diferentes tipos de materiales orgánicos procedentes de distintos residuos como fuente de materia orgánica, es una práctica común para mejorar las propiedades del suelo y podría ser un enfoque amigable y rentable para el medio ambiente para restaurar áreas extensas con un nivel moderado de contaminación. El uso de materiales procedentes de residuos es además una alternativa para su reciclaje y reutilización. Estos materiales mejoran la fertilidad del suelo y la productividad de la planta, y también disminuyen la disponibilidad de elementos traza. Enmiendas orgánicas tales como compost o turba, que contienen una alta proporción de materia orgánica humificada que puede disminuir la biodisponibilidad de metales en el suelo por adsorción y por la formación de complejos estables con sustancias húmicas , ya que los ácidos húmicos tienen una gran capacidad para retener o quelatar los metales. Los materiales calizos se usan para aumentar el pH de los suelos ácidos (encalado) y reducir la toxicidad de los metales en los suelos. Generalmente, el encalado es muy eficiente en la inmovilización de los elementos traza catiónicos, cuya solubilidad decrece al aumentar el pH, favoreciendo su adsorción sobre los materiales al suelo, así como su precipitación, con lo que decrece drásticamente su concentración en la disolución del suelo. El efecto del encalado es el opuesto para los elementos traza que forman oxianiones, como los arseniatos, molibdatos, cromatos, etc., que aumentan su solubilidad en medio alcalino, o para los metales pesados asociados a la materia orgánica que también aumentan su solubilidad en medio alcalino. Los fosfatos, inmovilizan los metales existentes en la disolución del suelo, reduciendo de esta forma la disponibilidad para las plantas y la movilidad para el transporte. Las enmiendas inorgánicas más utilizadas en la inmovilización de elementos traza en suelos contaminados son : óxidos de Fe y Mn, aluminosilicatos, beringita, cenizas volantes, etc. Los óxidos de Fe y Mn puedan absorber o complejar iones metálicos. Materiales ricos en óxidos de Fe se emplean en suelos contaminados con arseniatos. También se usan minerales de la arcilla como las esmectitas, las zeolitas y subproductos como la beringita (aluminuisilicato obtenido en la combustión en lecho fluidizado de residuo de carbón, con ilita como mineral mayoritario)., No

Los datos se componen de grupos de 3 imágenes de microscopía XPEEM correspondientes a 5 islas nanométricas de magnetita. Cada isla está identificada en el nombre de los datos como i1, i2….i5, y las tres imágenes de cada isla con el identificador R0, R60 y R120., We have grown high quality magnetite microcrystals free from antiphase boundaries on Ru(0001) by reactive molecular beam epitaxy, conserving bulk magnetic properties below 20 nm thickness. Magnetization vector maps are obtained by X-ray spectromicroscopy and compared with micromagnetic simulations. The observed domain configurations are dictated purely by shape anisotropy, overcoming the possible influences of (magneto)crystalline anisotropy and defects, thus demonstrating the possibility of designing spin structures in ultrathin, magnetically soft magnetite at will., UE, programa H2020, Proyecto AMPHIBIAN n º 720853., Peer reviewed

DISTANTCOM Cruise (29HE20160204) carried out on the Research Vessel Hespérides in 2016, The main objective of the project is to understand the diversity and structure of Antarctic marine benthic communities. The ecological activity of marine natural products from Benthic organisms will be studied using chemical ecology experiments in situ. We will collect various marine invertebrates (stars, worms, snails, etc.) and we will study its behavior in the laboratory. We will try find out what chemical defenses they use to repel their predators or to keep clean, preventing organisms from adhering to their surface. These chemicals can also have an activity potentially useful biological in the form of medicines. For putting a example, the compound that prevents the cells of your enemy from spreading it could serve to prevent the development of cancer cells. We will try to learn more about how the animals of the Antarctic fund live: what trophic relationships do they have (who eats whom), what relationships symbiotics present (who lives with whom) or what pollutants accumulate (that they feel bad). We intend to know also their relations of kinship, trying to unveil the family tree of some species, and what factors have conditioned its current distribution. This is important also in relation to climate change. Sampling has been done with beam trawls and with divers

MIXTO Cruise (29HE20160306) carried out on the Research Vessel Hespérides in 2016, The main objectives of this survey are: 1) Mapping sedimentary features resulting from the interaction of water bodies with gravitational features ( valleys and landslides ) from the upper slope 2) seismic analysis for the establishment of a model facies sedimentary 3) Determine the recent sedimentary processes. During the cruise, which in its data collection stage in the south of Buenos Aires completed 990 miles of navigation between 39 and 42 ° Lat. S, geomorphological and morphosedimentary features of the outer platform and slope at depths between 90 and 4000 meters were analyzed, sedimentary structures of the shallow subsoil (up to 100 m below the bottom) were analyzed, and recent processes related to the interaction between geological factors (transport of sediments, erosion-deposition processes on terraces and gravitational on slopes and underwater canyons) and oceanographic (interfaces between water masses, longitudinal currents to the margin and turbidity). The instruments used were: multi-beam echo sounder of shallow and deep water, parametric profiler TOPAS, 12 KHz echo sounder, biological echo sounder, XBT-XSV and Doppler ADCP

INCRISIS Cruise (29HE20160523) carried out on the Research Vessel Hespérides in 2016, On January 25, 2016 there was an earthquake of magnitude Mw = 6.3 with epicenter in the Alboran Sea (35.6ºN, 3.81ºW), which caused material damage in Melilla and Moroccan cities; It was also felt in the southeast of Iberia. It is the main earthquake of the seismic crisis that continues today. Its focal mechanism and the distribution of replicas suggest the activity of an unknown fault of direction NNE-SSO of about 25 km in length, in the western part of the Dorsal de Alboran. This seismic activity seems to be in continuity with the earthquakes of Alhucemas of 1994 and 2004, and associated with the prolongation of a fault zone in the rifeña mountain range. The realization of this marine geology cruise is a unique opportunity to know the effects that the seismicity of these characteristics causes in the bottom and sub-fund of the Alboran Sea, such as displacements of the seabed, triggering of landslides and other risks associated with them ( eg, tsunamis) that would affect both Moroccan and Spanish coastal areas. The results of this campaign will be analyzed in detail during the development of a new research project (DAMAGE) requested to the MINECO call and will contribute to characterize the geological hazard of active faults in the Alboran Sea. The specific objectives of this cruise include: 1) Cartography and characterization of sedimentary and tectonic features and comparison with the previous data 2) Stratigraphic analysis, simian facies and deformation structures 3) Determination of sedimentary and tectonic processes triggered by the earthquake and the seismic crisis
