Wave storms and river inputs have been found to be the dominant forcing mechanism of sediment transport in continental shelves dominated by medium to large rivers around the world (e.g. Drake and Cacchione, 1985; Sherwood ...
León Arteaga, Angélica M. de (Fecha de defensa: 2002-07-19)
In this research we tested two data analyses methodologies, namely the empirical orthogonal functions (EOFs) to estimate hydrographic CTD data profiles, and a successive corrections algorithm (SC) to project the results ...
Medina Enriquez, Pablo (Fecha de defensa: 2002-07-17)
The objectives of the thesis were, on the one hand, to test the possibilities of a well-known experimental configuration (oscillating grid mixing box), used to study stratified fluids in turbulent flows with zero-mean, on ...

Dinoflagellates are one of the most abundant and diverse groups of microalgae. Many dinoflagellates are covered with cellulose plates, whereas others lack these plates and are hence referred to as athecate or unarmoured. ...
Ahumada Sempoal, Miguel Angel (Fecha de defensa: 2014-12-11)
A high-resolution (~1.2km) 3D circulation model nested in one-way to a coarse-resolution (~4km) 3D regional model was used to examine the interaction between the Northern Current and the Blanes submarine canyon (~41°00’-41°46’N; ...
Mestres Ridge, Marc (Fecha de defensa: 2002-07-15)
Traditionally, the sea has been considered as the ultimate sink of most pollutions, due to its huge volume and assimilating capacities, and the coastal waters, because of their intermediate position between deep seas and ...

L'objectiu d'aquesta tesi és implementar un sistema d'assimilació de dades a un model hidrodinàmic de la plataforma continental catalana. Aquest sistema ens permetrà combinar la informació proporcionada per les dades ...
Navarro Cuenca, Anna (Fecha de defensa: 2012-06-18)
Field biomonitoring based on molecular biomarkers detects early warning signals of stress suffered by organisms exposed to contamination. The lower part of the Ebro River basin has a long pollution history related to the ...
Mamouridis, Valeria (Fecha de defensa: 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 ...
Bregoli, Francesco (Fecha de defensa: 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 ...
Morell Ybarz, Maria (Fecha de defensa: 2012-05-04)
The morphological study of the Odontocete organ of Corti including possible pathological features resulting from sound over-exposure, represent a key conservation issue to assess the effects of acoustic pollution on marine ...
