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 ...
Benavente Marín, Mario (Date of defense: 2024-07-30)
[eng] The Azores Archipelago, strategically located in the central North Atlantic, serves as a key location for analyzing regional atmospheric dynamics. Thus, climate reconstructions derived from from sediments of the ...
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 ...
Juan Carbonell, Carlos de (Date of defense: 2024-05-17)
[eng] Ectothermic animals are highly sensitive to changes in the environmental temperature. As ocean temperatures rise, a major concern is the potential impact of warming on copepods, which are crucial contributors to ...
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 ...

Galiana Blanch, Savitri (Date of defense: 2016-09-27)
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 ...
Guzman Vendrell, Montserrat (Date of defense: 2015-11-30)
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 ...
Veloy Dominguez, Carlos (Date of defense: 2024-10-25)
[eng] Marine communities have been affected by multiple stressors increasing over the last decades, such as overfishing and climate change, resulting in negative effects throughout ecosystems. However, these impacts do not ...
Campos Durán, Daniela (Date of defense: 2023-11-23)
[eng] Irazu is the highest volcano in Costa Rica (3427 m.a.s.l.); it constitutes an andesitic shield, with two main craters at the top and several pyroclastic cones cuspidal, and adventitial on the South Flank. The first ...
