The production and subsequent emission of volatile compounds is one of the numerous ways by which microbial plankton participate in the cycling of elements and influence the Earth's climate. Dimethylsulfide (DMS), produced ...
Valdemoro García, Herminia (Date of defense: 2005-02-25)
Esta tesis analiza y cuantifica los efectos de la interacción entre la morfodinámica y los principales usos y funciones de la zona costera (natural, protección y recreativa). Para cada tipo de interacción se propone un ...
Lana Celaya, María Aránzazu (Date of defense: 2012-02-10)
Marine aerosols have a large potential to influence the Earth¿s climate through their effects on cloud properties. The CLAW hypothesis goes further, and suggests that marine aerosols formed by the sulphur cycle of the ocean ...
Flexas Sbert, Maria del Mar (Date of defense: 2003-07-11)
The Northern Current flows cyclonically contouring the continental slope in the NW Mediterranean. At the entrance of the Gulf of Lions this current is about 20 -- 30 km wide and flows along the deepest half of the continental ...
