a Benthic δ18O from Site 1233 (green, crosses), alkenone-derived sea surface temperatures (SST) from Site 1233 (ref. 46; age model updated according to our current age model; blue), and a stacked Antarctic δ18O record consisting of five (WAIS Divide, EDML, EDC, Dome Fuji, Talor Dome) Antarctic ice cores47 (yellow). b Reconstructed SWW changes in latitude (black) and strength (gray)48 and Sortable silt mean grain size variations \((\overline{{{\rm{SS}}}})\) (paleocurrent proxy) from Site 1233 (red, thick line is a 3% weighted smooth made with Kaleidagraph 5.0. c Benthic TMg/Ca from Site 1233 (black, dots) and error band in gray. d δ18OIVC-seawater reconstructions from Site 1233 (dashed blue, triangles) and error band in blue. e Alkenone-derived SST from GC- 528 (ref. 49; red) and benthic-planktic 14C age difference from MD07-3088 (ref. 24; blue). Error bands are based on the propagated errors given in the method section. Shaded purple areas indicate Heinrich Stadial 1 (H1), the Bølling-Allerød /Antarctic Cold Reversal (BA/ACR), and the Younger Dryas (YD).
