    Trophic cascade modelling in bathyal ecosystems 

    Mamouridis, Valeria (Date of defense: 2015-05-15)

    Different aspects of the bathyal ecosystem have been treated with the final aim to investigate trophic cascades driven by fishery (top-down control), a phenomenon that in bathyal systems has never been studied. This was ...

    Tsunamis provoked by fast granular landslides : 3D laboratory experiments on generation and initial propagation of waves 

    Bregoli, Francesco (Date of defense: 2015-11-12)

    Landslides and debris flows falling into reservoirs, natural lakes, fjords or seas can generate impulsive waves, which can be assimilated to tsunamis. This phenomenon, also known as "landslide tsunami", can be highly ...

    Brenner Guillermo, Jorge (Date of defense: 2007-05-04)

    Este estudio parte de la hipótesis que los servicios del ecosistema son cada vez más escasos debido a la seria degradación de su capacidad para proporcionar servicios eficientemente en la costa Catalana, España. El estudio ...

    Water mass variability in the eastern South Pacific and the ventilation of the oxygen minimum zone 

    Llanillo del Río, Pedro José (Date of defense: 2014-10-29)

    This dissertation aims at extending our knowledge of the ESP OMZ through two main approaches. The first approach is based on tracer analysis and inverse modeling techniques. Such techniques are applied to hydrographic ...

    Wind-driven currents in the coastal and equatorial upwelling regions 

    Castellanos Ossa, Paola (Date of defense: 2012-11-12)

    During the last two decades the scientific community has recognised the importance of the tropical Atlantic Ocean and the upwelling regions on the Earth's climate. This recognition has opened new questions such as: ¿What ...
