Royer, Sarah-Jeanne (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 ...
Nos Francisco, David (Date of defense: 2024-02-06)
[eng] Understanding and monitoring the impacts of pollution on marine ecosystems leads the list of challenges of the United Nations Ocean Decade as crucial steps towards achieving a healthy ocean. The marine environment ...
Camanni, Giovanni (Date of defense: 2014-10-20)
The Taiwan thrust belt is generally thought to develop above a shallow, through-going basal detachment confined to within the sedimentary cover of the Eurasian continental margin. A number of data sets, however, such as ...
Olivé Abelló, Anna (Date of defense: 2023-03-20)
[eng] The returning limb of Atlantic Meridional Overturning Circulation (AMOC) is partly supplied by the cold-fresh waters that enter through the Drake Passage. Up to the isoneutral 28.0 kg m−3, the mean water inflow through ...
