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 ...
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 ...
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 ...
[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), ...
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, ...
[eng] Many sediment-covered mountain areas affected by the growth of Pleistocene glaciers are over-consolidated. Palaeoglacial conditions are deduced from glacial consolidation and site investigations. Geomorphological evidence ...
[eng] In September 2017, a no-take fishery reserve was established in the deep waters of the northwestern Mediterranean Sea, specifically focused on recovering the Norway lobster (Nephrops norvegicus) population. The main ...
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 ...
[eng] Marine phytoplankton are responsible for approximately half of the photosynthetic production of organic matter (OM) and oxygen in Earth. The composition and reactivity of phytoplankton- derived OM influences two of ...
[eng] During the Messinian Salinity Crisis (MSC, 5.97 – 5.33 Ma), an environmental crisis unparalleled in recent geological history, thick evaporites were deposited in the Mediterranean Basin associated with major erosion ...
[eng] The Earth System is formed by four components that sustain life: the atmosphere, the biosphere, the hydrosphere and the geosphere. The complex region in which these elements interact is known as the ‘Critical Zone’. ...
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. ...
