    Glaciar: software de visualización de datos de recursos hídricos y atmosféricos

    Get PDF
    Se desarrolló un software de visualización para facilitar el análisis de la calidad de los recursos hídricos y atmosféricos a partir de datos públicos del medio ambiente. Se describen los sistemas de calidad del aire y del agua que el software permite integrar en las visualizaciones. Se explica el procedimiento de extracción de los datos desde cinco plataformas de datos abiertos. El software se distribuye en formato open source para facilitar su extensión, por ejemplo, en la visualización de datos generados por soluciones de IoT o recolectados mediante el uso de drones equipados con sensores.Sociedad Argentina de Informática e Investigación Operativ

    Seismic characterization of the Alhama de Murcia Fault

    La falla de Alhama de Murcia (AMF) es una de las fallas más activas de la Península Ibérica y fue la causante del terremoto de Lorca de 2011 que significó numerosos daños materiales e incluso víctimas mortales. Esta falla oblicua en dirección NE-SO, que se extiende por más de 100 km, ha sido estudiada en superficie pero poco se sabe de su estructura en profundidad. Esto es especialmente importante para poder interpretar de forma correcta los numerosos datos paleosísmicos que se están obteniendo, ya que conocer la relación estructural en profundidad de las distintas ramas que forman la AMF es esencial. Por este motivo, y dentro del marco del proyecto InterGEO, se ha realizado una campaña de adquisición de datos sísmicos 2D a lo largo de la AMF, centrándose en los segmentos más interesantes en la zona de Lorca-Totana. Aquí se presentan los los resultados preliminares del procesado de algunos de los perfiles adquiridos en esta campaña que muestran la primera imagen estructural de la falla en profundidad y que permitirá entender el comportamiento de dicha falla, así como determinar su relevancia desde el punto de vista del riesgo sísmico.The Alhama de Murcia fault (AMF) is one of the most active faults of the Iberian Peninsula and the source of the Lorca 2011 earthquake that caused significant damage including several casualties. This NE-SW oblique fault, extended more than 100 km, has been extensively mapped to characterize its surface structure but almost no information is available of the structure and geometry at depth. This is specially significant in order to correctly interpret the obtained paleoseismic data considering that the knowledge of the structural relationship in depth between different branches of the fault is necessary. Accordingly, and within the InterGEO project, a 2D seismic reflection acquisition experiment was carried out along the AMF, focusing in the more interesting segments in the Lorca-Totana area. In this work we present the very first results of the acquired seismic reflection profiles that show the first structural image in depth of this fault which allow us to understand the seismic behaviour of the fault, and determine its relevance in seismic hazard.Depto. de Geodinámica, Estratigrafía y PaleontologíaFac. de Ciencias GeológicasTRUEMinisterio de Economía y Competitividad (MINECO)Generalitat de Catalunyapu

    Intra-articular temperatures of the knee in sports – An in-vivo study of jogging and alpine skiing

    <p>Abstract</p> <p>Background</p> <p>Up to date, no information exists about the intra-articular temperature changes of the knee related to activity and ambient temperature.</p> <p>Methods</p> <p>In 6 healthy males, a probe for intra-articular measurement was inserted into the notch of the right knee. Each subject was jogging on a treadmill in a closed room at 19°C room temperature and skiing in a ski resort at -3°C outside temperature for 60 minutes. In both conditions, temperatures were measured every fifteen minutes intra-articulary and at the skin surface of the knee. A possible influence on joint function and laxity was evaluated before and after activity. Statistical analysis of intra-articular and skin temperatures was done using nonparametric Wilcoxon's sign rank sum test and Mann-Whitney's-U-Test.</p> <p>Results</p> <p>Median intra-articular temperatures increased from 31.4°C before activity by 2.1°C, 4°C, 5.8°C and 6.1°C after 15, 30, 45 and 60 min of jogging (all p ≤ 0.05). Median intra-articular temperatures dropped from 32.2°C before activity by 0.5°C, 1.9°C, 3.6°C and 1.1°C after 15, 30, 45 and 60 min of skiing (all n.s.). After 60 minutes of skiing (jogging), the median intra-articular temperature was 19.6% (8.7%) higher than the skin surface temperature at the knee. Joint function and laxity appeared not to be different before and after activity within both groups.</p> <p>Conclusion</p> <p>This study demonstrates different changes of intra-articular and skin temperatures during sports in jogging and alpine skiing and suggests that changes are related to activity and ambient temperature.</p

    Long-term changes in habitat and trophic level of Southern Ocean squid in relation to environmental conditions

    Long-term studies of pelagic nekton in the Southern Ocean and their responses to ongoing environmental change are rare. Using stable isotope ratios measured in squid beaks recovered from diet samples of wandering albatrosses Diomedea exulans, we assessed decadal variation (from 1976 to 2016) in the habitat (δ13C) and trophic level (δ15N) of five important Southern Ocean squid species in relation to indices of environmental conditions—Southern Oscillation Index (SOI) and Southern Annular Mode (SAM). Based on δ13C values, corrected for the Suess effect, habitat had changed over the last 50 years for Taonius sp. B (Voss), Gonatus antarcticus, Galiteuthis glacialis and Histioteuthis atlantica but not Moroteuthopsis longimana. By comparison, mean δ15N values were similar across decades for all five species, suggesting minimal changes in trophic levels. Both SAM and SOI have increased in strength and frequency over the study period but, of the five species, only in Taonius sp. B (Voss) did these indices correlate with, δ13C and δ15N values, indicating direct relationships between environmental conditions, habitat and trophic level. The five cephalopod species therefore changed their habitats with changing environmental conditions over the last 50 years but maintained similar trophic levels. Hence, cephalopods are likely to remain important prey for top predators in Southern Ocean food webs, despite ongoing climate change
