Pascual Barrera, Alina E. (Date of defense: 2013-06-26)

Actualmente, la problemática que enfrentan las zonas costeras del Mediterráneo en general y la Comunidad Valenciana en particular, es la generación de grandes cantidades de agua residual urbana, principalmente durante la ...

Ultrastructural analysis of odontocete cochlea 

Morell Ybarz, Maria (Date of defense: 2012-05-04)

The morphological study of the Odontocete organ of Corti including possible pathological features resulting from sound over-exposure, represent a key conservation issue to assess the effects of acoustic pollution on marine ...

Toxicogenomic analysis of environmental impact in aquatic systems 

Navarro Cuenca, Anna (Date of defense: 2012-06-18)

Field biomonitoring based on molecular biomarkers detects early warning signals of stress suffered by organisms exposed to contamination. The lower part of the Ebro River basin has a long pollution history related to the ...

Wind-driven currents in the coastal and equatorial upwelling regions 

Castellanos Ossa, Paola (Date of defense: 2012-11-12)

During the last two decades the scientific community has recognised the importance of the tropical Atlantic Ocean and the upwelling regions on the Earth's climate. This recognition has opened new questions such as: ¿What ...

Interactive effects of vertical mixing, solar radiation and microbial activity on oceanic dimethylated sulfur cycling 

Galí Tàpias, Martí (Date of defense: 2012-12-18)

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 ...
