Element concentrations and stable isotope record of planktonic foraminifera of sediment cores from the northeastern Brazilian Continental Margin
Detailed 14C AMS data and isotope based stratigraphies from high-resolution paleoceanographic records for the last 22 ka of cores from the upper continental slope off NE Brazil reveal sedimentation rates of up to 100 cm per 1000 yr. Variations in the sediment composition relate to changes in the inp...
