The biology of blue whiting (Micromesistius poutassou) in the NW Mediterranean: a species under siege by overfishing and climatic constraints
Blue whiting, Micromesistius poutassou (Risso, 1827), is a mesopelagic gadoid widely distributed in the North Atlantic and the Mediterranean Sea, inhabiting waters over the shelf edge and continental slope. The species ...
Pore pressure build-up in mixed contourite-turbidite systems: the SW Iberian margin
Contourite drifts are the depositional expression of bottom currents, which are capable of shaping the morphology of the seafloor by transporting, eroding and reworking marine sediments, and are distributed on continental ...
Development of GasChromatographic/Mass Spectrometric procedures and Synchroton Radiation based techniques for the study of painting materials in works of art
El estudio de muestras de pintura persigue diferentes objetivos. Por un lado, identificar los materiales y técnica de la pintura de una época y por lo tanto el know-how de un período histórico. Por otra parte, estudiar la ...
Geophysical constraints on the nature of geological domains of continental rifted margins: examples from the West Iberia margin and Ligurian Basin
In this PhD work, we carry out a geophysical and geological study of two classical examples of rifted continental margins: the Gulf of Lions (GoL), located in the Western Mediterranean, and the Tagus Abyssal Plain (TAP), ...
Tectonic evolution of the São Vicente area and tsunamigenic potential of the active structures in the SW Iberian margin: Implications for hazard assessment
The southwestern margin of the Iberian Peninsula, which includes the Gulf of Cadiz, is characterized by a present-day active deformation mainly driven by the NW-SE trending convergence between the African and Eurasia plates. ...
Connectivity of the deep-sea red shrimp Aristeus antennatus in the northwestern Mediterranean Sea by modeling the Lagrangian transport of larvae
The connectivity of the deep-sea blue and red shrimp Aristeus antennatus, the most targeted species by trawl fisheries in the western and central Mediterranean Sea, is an information of interest for the management policies ...
Diel feeding rhythms in marine protistan grazers
Protistan grazers are a key component of marine planktonic food webs. These marine protists are the major grazers of pelagic primary production in the oceans and, therefore, they display a crucial role in marine ...
Aplicación de herramientas de gestión por ecosistema para su uso en la gestión integrada de zonas costeras (GIZC): el caso del delta de la Tordera y la playa de S'Abanell (Blanes)
Las zonas costeras, y en especial las playas, son la unión principal entre la tierra y el mar, siendo el escenario de infinidad de interacciones causadas por factores muy diversos, desde cambios producidos por la dinámica ...
Active tectonics in Northern Africa: The Nubia-Eurasia boundary in Tunisia
This PhD thesis presents a geological and geophysical study that characterizes the Quaternary stratigraphy, geomorphology, recent tectonics, and discusses their implications to understand the geodynamic evolution of North ...
Inversion of multichannel seismic data by combination of travel-time and full-waveform tomography
This thesis presents the implementation and application of a procedure combining different geophysical techniques to extract high-resolution information that helps characterizing the structure and properties (p-wave velocity, ...
Effects of CO2 and long day length on primary productivity in the Arctic Ocean: a perspective on climate change = Efectos del CO2 y largos fotoperiodos en la productividad primaria del Océano Ártico: una perspectiva sobre el cambio climático
Climate change, caused by anthropogenic emissions of carbon dioxide (CO2) and other greenhouse gasses into the atmosphere, is producing profound impacts on ecosystems. The Arctic Ocean is one of the most vulnerable regions ...
Origen de la estructura de la caldera Cañas Dulces y su relación con el recurso geotérmico de alta entalpía
El ambiente geotectónico en que se ubica Costa Rica, ha permitido el desarrollo de un arco volcánico activo, contexto geológico que favorece la formación de sistemas hidrotermales con potencial geotérmico; fuente de energía ...
Geophysical evidence of the preparedness for a volcanic eruption: El Hierro 2011-2012
The observational data recorded by the monitoring networks during El Hierro 2011-2012 volcanic unrest and eruption, allowed us to conduct a study of the volcanic eruptive phenomena with that wide view. The lack of previous ...
Developing a management strategy for the red shrimp Aristeus antennatus fishery in the northwestern Mediterranean Sea = Desarrollo de una estrategia de gestión para la pesquería de la gamba roja Aristeus antennatus en el Mediterráneo Noroccidental
The deep-sea red shrimp Aristeus antennatus is one of the main target species for bottom trawl fishery in the northwestern Mediterranean Sea. In the Catalan region, this species is fished along the continental margin of a ...
Caracterización gravimétrica de zonas de rift en islas volcánicas oceánicas : aplicación a las islas de Tenerife y el Hierro
Los sistemas de rift en configuraciones volcánicas, se encuentran relacionadas con crecimiento de grandes edificios volcánicos y se definen como áreas de la corteza sometidas a esfuerzos extensivos que generan fracturas ...
The origin and tectono-sedimentary structure of the Alboran Basin
In this PhD thesis we present a geophysical study of the westernmost Mediterranean basin: the Alboran Basin. This basin is located between the Iberian Peninsula and North Africa, and it is surrounded by the Betics and Rif ...
Tectonic structure and formation kinematics of the Western Mediterranean basins
In this work we present a geophysical study of three Western Mediterranean basins: Valencia Trough, Gulf of Lions and Algero-Balearic Basin. The work aims to define the tectonic structure, nature of the basement, and to ...
North Atlantic Oscillation imprints in the Central Iberian Peninsula for the last two millennia: from ordination analyses to the Bayesian approach
The climate variability of the Iberian Peninsula (IP) can be explained in terms of relatively few large-scale atmospheric modes, such as the North Atlantic Oscillation (NAO), the East Atlantic (EA) and the Scandinavian ...
Two-dimensional modeling and inversion of the controlled-source electromagnetic and magnetotelluric methods using finite elements and full-space PDE-constrained optimization strategies
The controlled-source electromagnetics (CSEM) and magnetotellurics (MT) methods are common geophysical tools for imaging the Earth's electrical interior. To appreciate measured data, both methods require forward and inverse ...
Understanding the processes that controlled rifting of the Tyrrhenian basin
This thesis is focused in the processes that took place in the Tyrrhenian Sea, which is a Neogene basin belonging to the Western Mediterranean realm. Its formation is related with the subduction system of the African plate ...
