Marine mammals face numerous anthropogenic threats, including fisheries interactions, ocean noise, ship strikes, and marine debris. Monitoring the negative impact on marine mammals through the assessment of population ...
(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 ...
The water currents and the wave field at the Catalan coast (in the Northwestern Mediterranean Sea) are investigated. However, the main research is focused at the northern margin of the Ebro Shelf, where there is a relatively ...
The predictability of beach inundation is mainly related to wave runup and most of the formulations that have been developed focus on the hydrodynamics, disregarding the morphological changes caused during storms. For these ...
This Thesis conducts the study of bedform development and dynamics in the inner shelf integrating observations at different spatial and temporal scales. An initial assumption is that different scales of sedimentary processes ...
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 ...
The main objective of this thesis is the study of a marine sediment core located in front of French Guiana (7°48’75’’N i 53°0’80’’W -1233m bsl and 39m length), in northern South America. The last 415,000 years were studied ...
The Southwest Atlantic Ocean is a key component of the global climate system. It holds the Confluence of the Brazil and Malvinas Currents (BMC), one of the highest frontal systems of the world ocean. The BMC is the encounter ...
Coastal zones concentrate an elevated number of values both natural and socio-economic, making them very vulnerable to the potential effects of natural hazards. Therefore, effective risk management requires a holistic ...
Este trabajo presenta un marco metodológico para la estimación de la vulnerabilidad costera al impacto de tormentas a dos escalas, regional y local. Se hace una evaluación de la vulnerabilidad costera física mediante la ...
Con el objetivo de desarrollar una herramienta de gestión para la reducción del impacto de los efluentes sobre los ecosistemas receptores de una granja camaronícola en el Estero de Urías, Mazatlán, Sinaloa, México, se ...
Transparent exopolymer particles (TEP) and Coomassie stainable particles (CSP) are operationally defined as organic particles > 0.4 µm that are stainable with the dyes Alcian Blue (specific for acidic polysaccharides) and ...
Biological N2 fixation, the reduction of dinitrogen (N2) gas to biologically available nitrogen, is a fundamental process since it represents a source of new nitrogen for marine life in areas where this important element ...
The Global Ocean is the largest Earth compartment holding carbon and nutrients that reaches the upper-ocean at temporal scales ranging from months to 10 kyr. The availability of these nutrients is fundamental to sustain ...
Mediterranean marine ecosystems are fundamentally driven by their pelagic communities and small and medium-size pelagic fishes (SMPF) play crucial ecological roles. Although fluctuations of the populations of these organisms ...
This thesis aims to develop simple models that allow evaluating the relevance of the principal parameters that condition the energy flows in the ocean-atmosphere system, and how changes in these parameters impact the climate ...
En la actualidad, las decisiones en la ingeniería de costas y la gestión costera se apoyan, cada vez más, en los modelos numéricos predictivos de los procesos costeros, que por otra parte, se basan en modelos conceptuales ...
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 ...
Les imatges de teledetecció de la superfície oceànica proporcionen una vista sinòptica de la complexa geometria de la circulació oceànica, dominada per la variabilitat de mesoescala. Estructures com filaments i vòrtex són ...
In the vast network of the ocean, microbes are abundant and unevenly distributed. As an important microbial component, the protists play a key role in global biogeochemical cycles and contribute to the recycling of nutrients ...
