Coastal surface circulation of the Gulf of Cadiz from satellite altimetry measurements
The main objective of this thesis is to contribute to the understanding of coastal zone dynamics using high-resolution altimetry data. The study evaluates the possibility of studying mesoscale surface circulation in coastal areas, particularly in the Gulf of Cadiz, Spain, using high-resolution …

Seepage of hydrocarbon bearing fluids at the Carlos Ribeiro and Darwin mud volcanoes (Gulf of Cadiz)
… volcanism is an important pathway for transfer of deep-sourced fluids enriched in hydrocarbons and other elements into the ocean. Mud volcanoes (MVs) occur in abundance on all oceanic plate margins, so fluxes of methane (CH4) and other chemical constituents from mud volcanism are likely to be …

Deep submarine volcanoes in two geodynamic settings (Canary Basin and Gulf of Cadiz): morphology and shallow structure
… morphostructural and morphometric studies of diverse hot vent and cold seep seafloor features in two different settings: the Canary Basin and the Gulf of Cadiz, both along the Atlantic margin. The study areas include forty volcanic hydrothermal mounds (M00 to M45) in the central area of the …

The role of abiotic and biotic interactions in deep-sea benthic habitats of the northeastern Gulf of Cadiz
The Gulf of Cádiz is influenced by the collision of the Alborán Domain with the North African and South Iberian margins, which ultimately promotes hydrocarbon-rich fluid venting, among other geological processes. Regarding oceanography, the single and interactive effects of the Eastern North …

The gulf of cadiz as a natural laboratory for the validation and exploitation of coastal altimetry and model data
… can be complementary tools for the study of sea level variations. Nowadays, users of these tools demand high quality products in coastal zones. In this sense, this doctoral dissertation focusses on the validation of innovative products that entail an advance in the understanding of sea …

METAL BIOGEOCHEMISTRY OF A MINE CONTAMINATED EsTUARiNE-CoASTAL SYSTEM IN SW SPAIN
The aim of this project was to investigate the biogeochemistry and transport of metals in a river/estuarine system contaminated by acid mine drainage. The Rio Tinto and Rio Odiel drain a metalliferous mining area in the Iberian Pyrite Belt in the south-west of Spain. The pH values in the rivers …

Mixing and dynamics of the Mediterranean outflow
Hydrographic and expendable current profiler (XCP) data taken during the Gulf of Cadiz Expedition in September 1988 are analyzed to diagnose the mixing and dynamics of the Mediterranean outflow. The overall structure of the outflow is consistent with that described in the historical literature …

Investigation into the post-mortem transport of benthic foraminifera
… reflect the ecological conditions at the time of deposition. However, the distribution of taxa can be greatly affected by transport and reworking of tests. This is particularly important in high energy environments such as submarine canyon and fan systems, which are major pathways for sediment …

Dynamics of confined chemical gardens and implications for submarine methane hydrates
… reactors, can be used to reduce the complexity of the system: osmosis is removed when performed with injection, and buoyancy if placed horizontally; the results are thus only dependent on the relationship between flow and chemical reaction. Firstly, we analyse the behaviour of horizontal …

Variación anual de la abundancia de bacterias y de la contribución del nano y picofitoplancton a la producción fitoplanctónica total en el Golfo de Cádiz
… were studied during 2014 and 2015 in the Gulf of Cádiz. The highest chlorophyll concentrations are found at coastal stations in spring during both years. Pico and nanophytoplankton are the main contributor to total chlorophyll, with highest concentrations at the outer limit of the …

Conexión de procesos hidrológicos e hidrodinámicos entre el Golfo de Cádiz y el Mar de Alborán
La presente Tesis estudia dos procesos que son cruciales para comprender la respuesta de los productores primarios al forzamiento físico en el sistema golfo de Cádiz – estrecho de Gibraltar – mar de Alborán: (i) La dinámica de los aportes continentales de los ríos que descargan al golfo de Cádiz, …
