Paleoclimate records off and near Greenland. (a) Flux of calcareous foraminera in core 248260–2 (Ameralik Fjord, SW Greenland) as indicator of subsurface ocean warming³⁹. (b) Relative amount (%) of foraminifera C. neoteretis in core PO 243–451 (Igaliku Fjord, SW Greenland) as indicator of ocean subsurface warming⁴⁰. (c) Alkenone-based SST reconstruction from sediment core ER07 (Sermilik Ford, SE Greenland, this study). (d) Thermocline temperature reconstruction based in Mg/Ca in G. inflata from core RAPiD-17–5P plotted on a reversed Y axis (Iceland Basin)²⁸. (e) Diatom-based August SST reconstruction from core MD99–2322 (Kangerdlugssuaq Trough, SE Greenland)²⁶. (f) Diatom-based April sea-ice concentration anomalies in the same core as (e). (g) Greenland Sea winter sea-ice extent reconstruction of the Western Nordic Seas based on tree-ring widths and ice core ¹⁸O records from Fennoscandia and Svalbard, respectively⁴³. (h) Fram Strait sea-ice export reconstruction from the Storis index; a proxy for sea-ice in the EGC⁴⁶. Grey lines on (d) and (e) show 5-yr running means.
