Onset and evolution of the Scotia sea basins, Antarctica: tectonic, sedimentary and palaeoceanographic implications. PhD Thesis

The main aim of this study is to describe the onset and stratigraphic evolution of the south Scotia Sea sedimentary basins. The interplay between tectonics, sedimentary processes, oceanography and climate is explored to trace a regional evolution linked to water mass interchange between the Weddell Sea and the Pacific and Atlantic oceans. The basins´ stratigraphic architecture is studied in detail through a seismostratigraphic and morpho-structural analysis of available multichannel seismic profiles. Gravity and magnetic anomaly models are additionally considered to constrain the nature and age of the basins.
