Figure F13. Pleistocene summer sea-surface temperature (SSST) record obtained at subantarctic Site 1090 (after Becquey and Gersonde, 2002, in press). Benthic foraminiferal delta18O signal represents a composite constructed from core PS2489-2 and Site 1090. Variations in SSST (dark/blue line) and its standard deviation (light gray lines) were estimated using a planktonic foraminiferal transfer function. Vertical colored areas indicate modern temperature ranges at the Polar Front (PF), the Subantarctic Front (SAF), and the Subtropical Front (STF). Modern SSST at the core location is 10.2°C (Levitus and Boyer, 1994). MBE = Mid-Brunhes Event, B/M = Brunhes/Matuyama boundary (according to Shipboard Scientific Party, 1999), MPR = mid-Pleistocene Revolution. Age model according to Venz and Hodell (2002). MIS = marine isotope stage.
