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.-48.64.45Amazon BasinCoordenação de Aperfeicoamento de Pessoal de Nível Superiorhttps://doi.org/10.13039/50110000232249558SMCoordenação de Aperfeicoamento de Pessoal de Nível Superiorhttps://doi.org/10.13039/5011000023228881.712022/2022-1National Council for Scientific and Technological Developmenthttps://doi.org/10.13039/501100003593307179/2021-4National Council for Scientific and Technological Developmenthttps://doi.org/10.13039/501100003593312458/2020-7National Council for Scientific and Technological Developmenthttps://doi.org/10.13039/501100003593314830/2021-9National Science Foundationhttps://doi.org/10.13039/100000001EAR-1812681National Science Foundationhttps://doi.org/10.13039/100000001OCE-0823650São Paulo Research Foundationhttps://doi.org/10.13039/5011000018072018/15123-4São Paulo Research Foundationhttps://doi.org/10.13039/5011000018072018/23899-2São Paulo Research Foundationhttps://doi.org/10.13039/5011000018072019/24977-0São Paulo Research Foundationhttps://doi.org/10.13039/5011000018072021/00853-0São Paulo Research Foundationhttps://doi.org/10.13039/5011000018072021/08085-1São Paulo Research Foundationhttps://doi.org/10.13039/5011000018072022/06440-1São Paulo Research Foundationhttps://doi.org/10.13039/5011000018072022/06452-0São Paulo Research Foundationhttps://doi.org/10.13039/5011000018072022/07285-0São Paulo Research Foundationhttps://doi.org/10.13039/5011000018072023/05764-0
