Extended Data Fig. 6: dln from the Pacific sector of Antarctica, and the TAN1106-28 proxy records.
From: Synchronous bipolar retreat of mid-latitude ice masses during Heinrich Stadials
a, Summer sea-surface temperature (sSST) estimates at TAN1106-28 from the planktic foraminifera N. pachyderma (blue; 3-point moving average), and sampled SST from Talos (TAL) Dome6,127,128 (light blue). WDC dln anomaly8 (grey; thick line is 5-point moving average) are also shown. b, sSST estimates at TAN1106-28 (as in a) together with the mm-scale XRF ln(Canorm) for TAN1106-28 (dark blue; together with the Calcium content, open circles), known as a proxy for biogenic carbonate productivity77. c, XRF ln(Canorm) for TAN1106-28 (dark blue; as in b), the percentage of the (foraminifera-rich) >63 µm fraction (light purple) and WDC dln anomaly8 (as in a). The location of Talos dome and WDC is shown in Fig. 1 and Extended Data Fig. 5. Marine Isotope Stages (MIS) and Heinrich Stadials (HS) are numbered.
