contents Here we present radiocarbon from two marine sediment cores (CDH-5 and GGC-4) located in the western equatorial Atlantic, off the coast of the Amazon River mouth, along the path of the North Brazil Current, where Amazon-derived sediments accumulated. Radiocarbon data were obtained using radiocarbon ages of planktonic foraminifera, which were analyzed using accelerator mass spectrometry at the Woods Hole Oceanographic Institution (USA) and the Beta Analytic Laboratory (USA). All work was done at Beta in 4 in-house NEC accelerator mass spectrometers and 4 Thermo IRMSs. The "Conventional Radiocarbon Age" was calculated using the Libby half -life (5568 years), is corrected for total isotopic fraction and was used for calendar calibration where applicable.
