The Calib (Stuiver and Reimer, 1993) program (version 6.0, Marine09 calibration data set of Reimer et al., 2009) was used to convert 14C ages to calendar ages. The resulting age model suggests an average sedimentation rate of ~23 cm/ky throughout the deglacial interval. Calendar age differences between N. pachyderma (s) and N. pachyderma (d) at the same depths (Table 1) are mostly on the order of 100-200 years, except for a ~900-year difference just prior to the onset of the BA, which may reflect age differences in polar vs. subpolar water masses. These age discrepancies are taken into account by applying slightly different age models for N. pachyderma (s) vs. N. pachyderma (d) records (based on dual ages obtained at the four depth intervals listed in Table 1 in publication). Paired geochemical measurements of two planktonic foraminifer species, Neogloboquadrina pachyderma (dextral (d), or right-coiling) and N. pachyderma (sinistral (s), or left-coiling), constrain changes in upper ocean temperature and salinity and their relationship to global climate and deep ocean circulation. The oxygen isotope composition of foraminiferal calcite (d18Oc) reflects both ambient calcification temperature and seawater isotopic composition (d18Osw). Independent estimates of calcification temperature from Mg/Ca measurements differentiate temperature and d18Osw influences on d18Oc. ABSTRACT SUPPLIED BY ORIGINATOR: Millennial-scale climate fluctuations of the last deglaciation have been tied to abrupt changes in the Atlantic Meridional Overturning Circulation (MOC). A key to understanding mechanisms of MOC collapse and recovery is the documentation of upper ocean hydrographic changes in the vicinity of North Atlantic deep convection sites. Here we present new high-resolution ocean temperature and d18Osw records spanning the last deglaciation from an eastern subpolar North Atlantic site that lies along the flow path of the North Atlantic Current, approaching deep convection sites in the Labrador and Greenland-Iceland-Norwegian (GIN) Seas. High-resolution temperature and d18Osw records from subpolar Site 980 help track the movement of the subpolar/subtropical front associated with temperature and Atlantic MOC changes throughout the last deglaciation. Distinct d18Osw minima during Heinrich 1 (H1) and the Younger Dryas (YD) correspond with peaks in ice-rafted debris and periods of reduced Atlantic MOC, indicating the presence of melt water in this region that could have contributed to MOC reductions during these intervals. Increased tropical and subtropical d18Osw during these periods of apparent freshening in the subpolar North Atlantic suggest a buildup of salt at low latitudes that served as a negative feedback on reduced Atlantic MOC.
