We adopted a multiproxy approach to analyze marine sediment cores from the western equatorial Atlantic (WEA) to investigate paleoceanographic and paleoclimatic changes during Heinrich stadial 10. Bottom water ventilation in the WEA is reconstructed using manganese (Mn) content in bulk sediments and stable carbon isotope composition of benthic foraminifera (Cibicidoides wuellerstorfi). Upper stratification was derived from the ratio between two planktonic foraminifera species (Globigerinoides ruber branco and Neogloboquadrina dutertrei). To assess hydroclimatic conditions in Northeastern Brazil (NEB), we used bulk sediment ln(Ti/Ca) geochemistry. To measure the Ca(%), Ti(%), Mn(%) and ln(Ti/Ca) columns, a Malvern Panalytical Epsilon 1 spectrometer, installed at the Laboratory of Paleoceanography and Paleoclimatology (P2L) of the School of Arts, Sciences and Humanities of the University of São Paulo (EACH/USP), was used. And for the columns G. ruber d18O (VPDB), N. dutertrei d18O (VPDB), C. wuellerstorfi d13C (VPDB), C. wuellerstorfi d18O (VPDB) and Δδ18Odut-ruber, a Thermo Fischer Scientific MAT 253 mass spectrometer equipped with an automatic Kiel IV carbonate preparation device, installed at the Laboratory of Paleoceanography and Paleoclimatology (P2L) of the School of Arts, Sciences and Humanities (University of São Paulo, Brazil), was used. The equipment is registered on the laboratory website (http://p2l.each.webhostusp.sti.usp.br/).
