    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 ...

    The potential of carboxylesterase activity in the biomonitoring of marine pollution 

    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 ...

    The structure of the south‐central Taiwan thrust belt 

    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 ...

    Thermal compensation in marine copepods: long-term ecophysiological implications in Paracartia grani 

    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 ...

    Transformations and pathways of Southern Ocean waters into the South Atlantic Ocean 

    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 ...

    Two-dimensional modeling and inversion of the controlled-source electromagnetic and magnetotelluric methods using finite elements and full-space PDE-constrained optimization strategies 

    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 ...

    Understanding the processes that controlled rifting of the Tyrrhenian basin 

    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 ...

    Unravelling causes and consequences of marine biodiversity changes in East Atlantic and Mediterranean ecosystems 

    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 ...

    Volcanic risk assessment at Irazú volcano, Costa Rica 

    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 ...
