Abstract

To explore the paleoclimatic role of the NBC, (North Brazil Current), the AA. studied a sediment core from the upper continental slope off northeastern Brazil. They used radiocarbon dating and oxygen isotope data for age control. Variations in the carbonate content and the ratio between the elements Ti, Fe, and Ca were used as continental climate indicators. To reconstruct past hydrographic conditions, they measured the stable oxygen isotope ratios in the carbonate shells of 2 shallow-dwelling planktonic foraminifera. They found the last glaciation characterized by alternations in carbonate-dominated and terrigenous-dominated sedimentation
