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 ...
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 ...
The Aran Valley in Catalonia (Spain), was the site of large-scale Zn, Pb, Cu, Fe, and Ag mining from the late 19th century until approximately 1950. Although mining activities ceased over 70 years ago, some of the abandoned ...
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 ...
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 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 ...
[eng] Current knowledge of marine fungi is limited, marked by gaps in the understanding of their diversity, spatio-temporal patterns, and ecological roles within marine ecosystems. The underexplored nature of specific ...
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 ...
This dissertation is devoted to seismic tomography. I have implemented a new modelling tool for 3-D joint refraction and reflection travel-time tomography of wide-angle seismic data (TOMO3D). The reason behind this central ...
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 ...
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 ...
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 ...
La circulación oceánica de gran escala se encuentra relacionada con la pequeña escala a través de los procesos turbulentos, los cuales hacen posible el intercambio de energía cinética. Alrededor de la frecuencia de Coriolis, ...
[cat] L'estudi previ d'una part del contacte entre el Massís del Gaià i la fossa del Penedès (AMIGÓ, 1983) va donar com a resultat l'aportació d'una sèrie de dades referents a l'estructura i evolució cinemàtica de les ...
[eng] Carbon capture and storage (CCS) in saline aquifers is a proven technology aimed at reducing atmospheric CO2 emissions and mitigating the climate change crisis. CO2 injection acidifies the formation water inducing ...
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), ...
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 ...
Monogenetic volcanism is characterized by a large diversity of eruptive styles, morphologies and deposits. Monogenetic landforms are the result of a complex merging of internal (magma composition, vesiculation) and external ...
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, ...
Dimethylsulfide (DMS) and its algal metabolite precursor, dimethylsulfoproprionate (DMSP), are major players in the oceanic and atmospheric sulfur cycle. DMS is the most abundant volatile organic sulfur compound in the ...
