1. Marine aerosols, their precursors and their influence on clouds over the global ocean - Lana, Aránzazu
Marine aerosols have a large potential to influence the Earth’s climate through their effects on cloud properties. The CLAW hypothesis goes further, and suggests that marine aerosols formed by the sulphur cycle of the ocean and the atmosphere act as a mechanism for regulating the Earth's climate. This effect is produced through the influence of plankton emissions of sulphur compounds on cloud formation. Phytoplankton produces dimethylsulphide (DMS), a highly volatile sulphur compound. Once in the atmosphere, DMS is oxidized and becomes the main source of natural atmospheric sulphates. These sulphates act as condensation nuclei, particles that are essential for the...

4. Thermo-Hydro-Mechanical Impacts of Carbon Dioxide (CO2) Injection in Deep Saline Aquifers - Vilarrasa, Víctor
[EN] Coupled thermo-hydro-mechanical (THM) effects related to geologic carbon storage should be understood and quantified in order to convince the public that carbon dioxide (CO2) injection is safe. This Thesis aims to improve such understanding by developing methods to: evaluate the CO2 plume geometry and fluid pressure evolution; define a field test to characterize the maximum sustainable injection pressure and the hydromechanical (HM) properties of the aquifer and the caprock; and propose an energy efficient injection concept that improves the caprock mechanical stability in most geological settings due to thermo-mechanical effects. First, we investigate numerically and analytically the effect of...

5. Nomsothermal multiphase flow of brine and gas through saline media - Olivella, Sebastià
[EN] A new formulation for the coupled analysis of thermo- hydro- mechanical problems in saline media is presented. The work ranges from the establishment of the mass, momentum and energy balance equations to its numerical solution by means advanced numerical techniques, including the derivation of some constitutive laws. The resulting computer program (CODE-BRIGHT) can be used to analyze real problems of sealing systems built with porous salt aggregates, which was the original motivation of the work.

6. Metodología para la modelación hidrogeológica de medios fracturados - Martínez Landa, Lurdes
[EN] Low permeability fractured media (LFFM) can be viewed as consisting of a virtually impervious matrix transversed by more or less conductive fractures. Experience dictates that a few of these concentrate most of the flow, this controlling the overall behaviour of the medium. Therefore, they need to be characterized for proper understanding of the system. Unfortunately, no widely accepted methodology is available to this end. In this context the objective of this thesis is three fold:

7. Contaminants orgànics persistents a la conca mediterrània. El cas del delta de l’Ebre - Gómez Gutiérrez, Anna
