Seagrass meadow: a coastal protection perspective
(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 ...
Ecosystem modelling for the ocean decade - facing the challenge
(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 ...
The sand transport processes of bar cross-shore migration and beach recovery
(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 ...
Patterns of connectivity in marine microbial communities
(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 ...
An updated framework for inferring interior ocean circulation from high resolution marine satellite observations
(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 ...
Challenges for shellfish aquaculture in Mediterranean coastal areas
(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 ...
Technologically-sustained ecological monitoring of a coastal fish community with a highly integrated biological and environmental data
(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 ...
Assessment of the biological risks associated to the use of biosolids and wastewater
(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 ...
Pelagia noctiluca (Cnidaria: Scyphozoa) as an industrial research model: improvements in aquaculture techniques and preventive measures against their stings
(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 ...
El costo del impacto sobre el litoral debido al cambio climático en Cataluña
(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 ...
Return of the marine heterotrophic flagellates: diversity, distribution and gene expression patterns
(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 ...
Population dynamics, interactions and evolution of marine microbes using genomic approaches
(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 ...
Citizen sciences technologies for operational monitoring of aquatic ecosystems
(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 ...
Estudio paleoclimático del afloramiento ecuatorial del Océano Pacífico durante los últimos 160.000 años a partir de biomarcadores moleculares
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 ...
Linking hydrodynamic and biological processes in a shallow and micro tidal estuary : the case of Fangar bay (Ebro delta)
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, ...
Biodegradation of polycyclic aromatic hydrocarbons in the surface ocean
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 ...
Morpho-functionality of the toothed whale external ear canal
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, ...
Exploration and discovery of sponge assemblages on the continental shelf and slope of the Catalano-Balearic Sea by means of non-invasive techniques
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 ...
Retroflections in the tropical Atlantic Ocean
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). ...
Probabilistic characterization of single and concurrent metocean variables of Mexican coasts with seasonal variability using extreme value theory, with application to reliability of coastal structures
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 ...
