Pedrazzi, Dario (Fecha de defensa: 2014-03-07)
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 ...
Gras Andreu, Clàudia (Fecha de defensa: 2019-11-08)
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, ...
Royer, Sarah-Jeanne (Fecha de defensa: 2015-03-02)
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 ...
Turu, Valentín (Fecha de defensa: 2023-04-24)
[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 ...
Vigo Fernandez, Maria (Fecha de defensa: 2023-10-30)
[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 ...
Neukirch, Maik (Fecha de defensa: 2014-07-01)
Studies have proven that the desired signal for Magnetotellurics (MT) in the electromagnetic (EM) field can be regarded as 'quasi stationary' (i.e. sufficiently stationary to apply a windowed Fourier transform). However, ...
Sánchez López, Giomar (Fecha de defensa: 2016-09-16)
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 ...
González-Gaya, Belén (Fecha de defensa: 2015-10-02)
The Open Ocean has been recognized as playing a key role on global dynamics of pollutants due to its large coverage of the planet surface, its high degradation potential and its sink and accumulation capacities towards ...
Molina Zúñiga, Fernando (Fecha de defensa: 2017-09-27)
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 ...
Gómez de la Peña, Laura (Fecha de defensa: 2017-06-08)
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 ...
Mencaroni, Davide (Fecha de defensa: 2022-02-25)
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 ...
Cabrera Brufau, Miguel (Fecha de defensa: 2023-02-17)
[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 ...
Heida, Hanneke (Fecha de defensa: 2022-12-01)
[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 ...
Lago Cameselle, Alejandra (Fecha de defensa: 2015-11-16)
At the end of the Miocene (5.97-5.33 Ma), the Mediterranean basins underwent deep morphological and sedimentological changes as a result of the large-scale sea-level fall during the so-called Messinian Salinity Crisis (MSC) ...
Handoyo (Fecha de defensa: 2023-02-16)
[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’. ...
Sánchez Serra, Cristina (Fecha de defensa: 2021-09-09)
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. ...
Viñas Gaza, Marina (Fecha de defensa: 2017-01-20)
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 ...
Lloret Lloret, Elena (Fecha de defensa: 2023-05-17)
[eng] From an oceanographic perspective, seasonality has been widely studied, and abundant research exists about low trophic level organisms such as phytoplankton and zooplankton. Nevertheless, at a regional scale, this ...
Margalef Marrasé, Olga (Fecha de defensa: 2014-03-14)
The PhD entitled “Last 70kyr of Rano Aroi (Easter Island, 27ºS) peat record: New insights for Central Pacific paleoclimatology” presents an environmental and climate reconstruction of Easter Island during the last 70.000 ...
