• W2123288429 abstract "Two cores,Site 1089 (ODP Leg 177) and PS2821-1,recovered from the same location (40‡56 PS; 9‡54PE) at the Subtropical Front (STF) in the Atlantic Sector of the Southern Ocean,provide a high-resolution climatic record,with an average temporal resolution of less than 600 yr. A multi-proxy approach was used to produce an age model for Core PS2821-1,and to correlate the two cores. Both cores document the last climatic cycle,from Marine Isotopic Stage 6 (MIS 6,ca. 160 kyr BP,ka) to present. Summer sea-surface temperatures (SSSTs) have been estimated,with a standard error of ca. 8 1.16‡C,for the down core record by using Q-mode factor analysis (Imbrie and Kipp method). The paleotemperatures show a 7‡C warming at Termination II (last interglacial,transition from MIS 6 to MIS 5). This transition from glacial to interglacial paleotemperatures (with maximum temperatures ca. 3‡C warmer than present at the core location) occurs earlier than the corresponding shift in N 18 O values for benthic foraminifera from the same core; this suggests a lead of Southern Ocean paleotemperature changes compared to the global ice-volume changes,as indicated by the benthic isotopic record. The climatic evolution of the record continues with a progressive temperature deterioration towards MIS 2. High-frequency,millennial-scale climatic instability has been documented for MIS 3 and part of MIS 4,with sudden temperature variations of almost the same magnitude as those observed at the transitions between glacial and interglacial times. These changes occur during the same time interval as the Dansgaard^Oeschger cycles recognized in the N 18 Oice record of the GRIP and GISP ice cores from Greenland,and seem to be connected to rapid changes in the STF position in relation to the core location. Sudden cooling episodes (‘Younger Dryas (YD)-type’ and ‘Antarctic Cold Reversal (ACR)-type’ of events) have been recognized for both Termination I (ACR-I and YD-I events) and II (ACR-II and YD-II events),and imply that our core is located in an optimal position in order to record events triggered by phenomena occurring in both hemispheres. Spectral analysis of our SSST record displays strong analogies,particularly for high,sub-orbital frequencies,to equivalent records from Vostok (Antarctica) and from the Subtropical North Atlantic ocean. This implies that the climatic variability of widely separated areas (the Antarctic continent,the Subtropical North Atlantic,and the Subantarctic South Atlantic) can be strongly coupled and co-varying at millennial time scales (a few to 10-ka periods),and eventually induced by the same triggering mechanisms. Climatic variability has also been documented for supposedly warm and stable interglacial intervals (MIS 1 and 5),with several cold events which can be correlated to other Southern Ocean and North Atlantic sediment records.
