Controls on sedimentation in submarine canyons: Nazare, Setubal and Cascais canyons, West Iberian Margin
… Setúbal and Cascais canyons, west Iberian margin, in order to constrain the<br/>processes and controls of past and present sedimentation in this area. The results<br/>indicate that, during the glacial stages, turbidity currents are the dominant process of<br/>sediment transport, …

The Biogeochemical Cycling of Dissolved Organic Carbon in the Iberian Margin Upwelling System (NE Atlantic Ocean
… world's oceans and its determination at ocean margins, where the exchange of terrestrial and oceanic organic matter occurs, is important for estimating cross-slope fluxes to deep waters. With the increased accuracy and precision (-1%) of analytical methodologies, small changes in the DOC pool …

The Role of the Ocean in MIS 4 Climatic Changes and Atmospheric CO₂ Variability: a Geochemical Fingerprinting Approach
… a suite of sediment cores retrieved from the Iberian Margin in the Northeast Atlantic, and a single core from the deep Sub-Antarctic Atlantic core site. This thesis ultimately aims to enhance the current understanding of the ocean’s role in and response to abrupt and orbital-scale climate …

Environmental magnetic applications of first-order reversal curve diagram analysis
… mineral composition is obtained from the Iberian Margin, spanning 194,000 years over the past two glacial cycles. We identify three magnetic components, where the bulk susceptibility variations are controlled by a previously unreported magnetic mineral phase. Trabecular magnetite, named so …

Neoproterozoic to Holocene tectonothermal evolution of the southern Cantabrian Mountains NW Iberia, revealed by apatite fission-track thermochronology
… renewed tectonic activity along the northern Iberian margin, climaxing by latest Miocene (Messinian) time. Heterogeneous cooling of samples is evidenced from Early Pliocene time. Post-tectonic denudation is interpreted to have become the dominant infl uence of cooling in the study area. In …
