a Benthic δ13C from Site 1233 (black, thick line is a 3% weighted smooth made with Kaleidagraph 5.0) and Monte Carlo average of atmospheric δ13C from two Antarctic ice cores29 (red). b δ13C of N. dutertrei from Site 1238 (ref. 6; dark grey). c pCO2 reconstructions from Site 1238 (ref. 6; green) and Opal flux from V19-30 (ref. 33; dashed, brown). d Sortable silt mean grain size variations \((\bar{{\mbox{SS}}})\) (paleocurrent proxy) from Site 1233 (red, thick line is a 3% weighted smooth made with Kaleidagraph 5.0) and benthic Δ14C from Baja California sites16,18 (705 m water depths; dashed, blue). e Benthic-planktic 14C age difference from MD07-3088 (1536 m water depth; ref. 24; light blue). f Opal flux from the Pacific sector of the Southern Ocean38 (blue) and opal flux from the Atlantic sector of the Southern Ocean10 (dashed, green). g Global stack of atmospheric CO2 reconstructions8 (black). Shaded purple areas indicate Heinrich Stadial 1 (H1), the Bølling-Allerød /Antarctic Cold Reversal (BA/ACR), and the Younger Dryas (YD).
