Water mass variability in the eastern South Pacific and the ventilation of the oxygen minimum zone
(Universitat Politècnica de Catalunya, 2014-10-29)
Tesi
Accés obertThis dissertation aims at extending our knowledge of the ESP OMZ through two main approaches. The first approach is based on tracer analysis and inverse modeling techniques. Such techniques are applied to hydrographic ... -
Ocean velocities as inferred from Argo floats: methodology and applications
(Universitat Politècnica de Catalunya, 2014-07-03)
Tesi
Accés obertThe velocity fields inferred from the trajectories of Argo floats have proven to be a valuable tool for observing the major ocean currents. The velocity fields can be used to examine statistical properties at regional and ... -
Coastal vulnerability to storms at different time scales: application to the Catalan coast
(Universitat Politècnica de Catalunya, 2014-07-11)
Tesi
Accés obertStorm-induced impacts are known to cause important economic and environmental damages to coastal systems worldwide. Consequently, the relevance of including hazards and vulnerability assessments in coastal policies has ... -
The diversity of dinoflagellates belonging to the gymnodiniales from the catalan coast (NW Mediterranean Sea)
(Universitat Politècnica de Catalunya, 2014-02-28)
Tesi
Accés obertDinoflagellates are one of the most abundant and diverse groups of microalgae. Many dinoflagellates are covered with cellulose plates, whereas others lack these plates and are hence referred to as athecate or unarmoured. ... -
Distribution and partitioning of organic pollutants and effects in coastal birds
(Universitat Politècnica de Catalunya, 2013-11-14)
Tesi
Accés obertCoastal areas are very susceptible to contamination due to the interaction of marine and anthropogenic processes. Persistent Organic Pollutants (POPs) are organic compounds very resistent to photolysis and chemical and ... -
Distribution and population biology of pelagic decapod crustaceans of the western Mediterranean
(Universitat Politècnica de Catalunya, 2013-11-22)
Tesi
Accés obertThe present thesis provides new information about pelagic decapod crustaceans, specially so concerning the Mediterranean pasiphaeids. Remarkable differences in the pattern of distributions of the pasiphaeids were observed ... -
Coral reef ecosystem services economic valuation experiences from the South Pacific
(Universitat Politècnica de Catalunya, 2013-11-11)
Tesi
Accés obertEconomic approaches through ecosystem services (ES) valuation are increasingly recommended by conservation organisations to face main market externalities affecting biodiversity in general and coral reef ecosystems. In ... -
Optical propertiers of the dissolved organic matter as tracers of microbiological and geochemical processes in marine ecosystems
(Universitat Politècnica de Catalunya, 2011-10-07)
Tesi
Accés obertOceans store 685 Pg of organic carbon of which 662 Pg are in a dissolved form. The diversity of compounds that make up the dissolved organic matter (DOM) pool and the low concentration of each compound make the chemical ... -
Sediment dynamics and associated heavy metals in small river-and wave-dominated inner shelf (Barcelona city, Nw Mediterranean)
(Universitat Politècnica de Catalunya, 2013-10-24)
Tesi
Accés obertWave storms and river inputs have been found to be the dominant forcing mechanism of sediment transport in continental shelves dominated by medium to large rivers around the world (e.g. Drake and Cacchione, 1985; Sherwood ... -
Ecology of the marine copepod genus Oithona
(Universitat Politècnica de Catalunya, 2013-09-29)
Tesi
Accés obertCopepods have a crucial role in the pelagic marine ecosystem, for their participation in the nutrient cycling and carbon export in biogeochemical cycles, and their role as link organisms between primary producers and higher ... -
Biogeochemical controls of the transport and cycling of persistent organic pollutants in the polar oceans
(Universitat Politècnica de Catalunya, 2013-09-20)
Tesi
Accés obertHumanity is currently using more than 200000 synthetic organic compounds in many industrial, agricultural and domestic applications. Many of these chemicals reach the environment and have a harmful effect on ecosystems and ... -
Expressió gènica en microorganismes marins
(Universitat Politècnica de Catalunya, 2013-09-27)
Tesi
Accés obertAra que es comença a treure l’entrellat -o si més no a tenir una nova perspectiva- de la diversitat de microorganismes present als oceans gràcies a la biologia molecular i a la metagenòmica, el següent pas és esbrinar ...
