Sedimentology and geochemistry of gas hydrate rich sediments from the Oregon margin (Ocean Drilling Program Leg 204)

Piñero Melgar, Elena (Date of defense: 2009-05-22)

Gas hydrates have been recently recognized as a key factor affecting a number of global processes such as the climatic change, sea floor stability, etc. In this thesis we present the multidisciplinary study of gas hydrate ...

Storfjorden Trough Mouth Fan (Western Barents Sea): slope failures in polar continental margins; significance of stress changes and fluid migration induced by glacial cycles

Llopart Serra, Jaume (Date of defense: 2016-11-22)

The development of two Arctic Trough Mouth Fans (TMFs), the Storfjorden and Kveithola TMFs, is investigated by means of sub-bottom and seismic reflection profiles, multibeam bathymetry and sediment samples allowing their ...

Ultra-high resolution environmental and climatic reconstruction using oxygen and carbon isotopes of diatom frustules

Hernández Hernández, Armand (Date of defense: 2010-09-21)

Calcareous microfossils are not always present in marine or lacustrine sediments owing to unfavourable ecological or post-depositional conditions. These non-carbonated sediments sometimes contain abundant biogenic silica, ...

Variabilitat climàtica ràpida a la conca occidental del Mediterrani: registre sedimentològic / Rapid climate variability in the Western Mediterranean Basin: the sedimentological record

Frigola Ferrer, Jaime I. (Date of defense: 2012-12-05)

Aquesta Tesi Doctoral està centrada en la reconstrucció de les condicions climàtiques del passat a la conca occidental del Mediterrani, i més concretament en l’estudi de l’efecte de la variabilitat climàtica d’escala orbital ...
