Astudillo Gutiérrez, Carlos Salvador (Date of defense: 2024-06-26)
(English) Over the decades, the global coastlines have been a key indicator of the development of actual societies. However, the cost of this growth has resulted in the depredation of natural environments. The increased ...
Steenbeek, Jeroen (Date of defense: 2024-10-22)
(English) The worlds’marine ecosystems are degrading under wide ranges of ever intensifying, diversifying and co-occurring human pressures. Ecosystem-based management (EBM) approaches have emerged as an alternative to ...
Grossmann, Florian (Date of defense: 2023-09-05)
(English) The sustainable management of coastal regions requires profound understanding of the physical processes that govern them. Here, a central aspect is the onshore and offshore migration of sandbars, transporting ...
Marín Vindas, Carolina Alexandra (Date of defense: 2023-09-06)
(English) Marine microorganisms are fundamental for life on Earth. For example, they have produced most of the oxygen existing in our planet and are essential in biogeochemical cycles and energy flow to different trophic ...
Piracha, Aqeel (Date of defense: 2024-02-16)
(English) It was not until 1982 that Gösta Walin proposed a formal framework to connect heat input from the sun to the large-scale thermal circulation of the ocean through quantifying a sur- face ”drift” of water from high ...
Fernández Tejedor, Margarita (Date of defense: 2023-12-18)
(English) The increase in the production of marine bivalves targets the sustainable development of aquaculture to improve global food and nutrition security. Bivalve aquaculture is currently facing challenges and threats ...
Francescangeli, Marco (Date of defense: 2023-10-30)
(English) The Monitoring of coastal marine ecosystems has been traditionally carried out with man and vessel-assisted methodologies. In the last decades, new technologies have been progressively integrated by platforms ...
Sanz Lanzas, Claudia (Date of defense: 2023-05-26)
(English) The circular economy is an emerging concept presented as a solution to counteract the damage caused by the linear economic scheme followed in the past decades. It is based on the principle of "closing the life ...
Ballesteros Mascarell, Ainara (Date of defense: 2023-01-13)
(English) Jellyfish stings cause discomfort to users of the marine environment, who sometimes require medical assistance. Although jellyfish stings are common today, the scientific community remains in disagreement on how ...
Lomelí Quintero, Víctor Manuel (Date of defense: 2023-10-13)
(English) Climate change is a major issue that is having a significant impact on coastal areas globally. This phenomenon is generating processes of erosion, flooding and sea level rise, which is of great concern. These ...
Obiol Plana, Aleix (Date of defense: 2023-01-27)
(English) Marine heterotrophic flagellates (HF) are very small (2-5 µm) unpigmented protists that are dominant bacterial grazers in the ocean, where they link the transfer of carbon from bacterial cells to higher trophic ...
Latorre Pérez, Francisco (Date of defense: 2023-02-03)
(English) There is a myriad of microorganisms on Earth contributing to global biogeochemical cycles. In the surface ocean, the smallest microbes (picoplankton) are responsible for an important fraction of the total atmospheric ...
Rodero García, Carlos (Date of defense: 2023-05-29)
(English) Light attenuation is a critical factor in aquatic ecosystems for many physical and biological processes. Water transparency plays an essential role in understanding the variations of the ecological environment ...
Quirós Collazos, Lucía (Date of defense: 2022-06-27)
The present PhD thesis is focused on the paleoclimatic reconstruction of the Pacific Ocean equatorial upwelling conditions, east of the Galapagos Islands, over the last 160.000 years. This region is of great interest to ...
Fernández-Pedrera Balsells, Marta (Date of defense: 2022-05-24)
This thesis analyses the relationships between hydrodynamics (and their forcings) and biological variables in Fangar Bay based on in situ observations, numerical models and satellite data. Fangar Bay is a relatively small, ...
Martínez Varela, Alícia (Date of defense: 2022-04-29)
Increasing quantities of organic pollutants (OP) are being released to the environment, posing a threat to Earth’s life system. In the marine environment, OP pollution caused by oil spill accidents receives a lot of academic ...
de Vreese, Steffen (Date of defense: 2021-06-17)
While marine, anthropogenic noise pollution is a scientific and societal matter of concern, there is limited knowledge on how sea animals, particularly cetaceans, perceive their environment through sounds. Toothed whales, ...
Santín Muriel, Andreu (Date of defense: 2022-01-24)
Sponge assemblages dominate several distinctive, hard-bottom environments, being one of the most important structural organisms at several locations around the world. Although the Mediterranean sponge fauna is among the ...
Vallès Casanova, Ignasi (Date of defense: 2021-10-19)
The upper ocean circulation is the area of confluence of two major vertical cells: the large-scale overturning Atlantic Meridional Overturning Circulation (AMOC) and the regional relatively shallow Subtropical Cells (STCs). ...
Calderón Vega, Felícitas (Date of defense: 2021-04-20)
This thesis encompasses a set of different subjects related to metocean variables but studied from different perspectives. The metocean variables are mainly significant wave heights and wind velocities and, to a lesser ...
