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.
