| contents | To comprehensively document the δ13C content of the South Atlantic Central Water (SACW), we used high-resolution thermocline-dwelling foraminiferal δ13C data obtained from three distinct marine sediment cores situated in the NW, SW, and SE regions of the South Atlantic. Our dataset enables a comprehensive examination of millennial-scale variations in SACW δ13C content across the entire basin. Notably, the thermocline δ13C records from the SE and NW sectors of the South Atlantic consistently exhibit concurrent negative excursions during most of the Heinrich Stadials (HS), a pattern that contrasts sharply with the absence of such negative excursions in the thermocline δ13C record from the SW sector of the South Atlantic |
