Short summary
This paper is a contribution to the knowledge of the geological processes on the SW Atlantic. We tried to integrate data from different time-scales, such as the geological evolution (millions of years) to the hydrodynamic processes (days to years). The results allowed us to recognize the importance of the geological inheritance to the present morphology of submerged areas.

Short summary
In this paper we used sediment samples from the shelf and upper/middle slope off south-eastern Brazil in order to recognise the inorganic and organic signatures of the main current systems acting in the area. It was possible to identify the extension of the contribution of terrigenous sediments from the adjacent continent as well as to recognise the different geochemical signatures related to the Brazil Current, Intermediate Western Boundary Current and Deep Western Boundary Current.

Short summary
In this work we used a concept called geochemical fingerprinting, with isotopes of neodymium and lead as tools to recognize the main sources and the physical processes responsible for the transport and deposition of sediments on a large area of the South Atlantic margin. Distinct sources, such as Antarctica, the Andean Cordillera, the Río de la Plata basin, and old rocks from the Brazilian shield, are identified.
