The five cores used in the Antarctic deglacial water isotope composite are: Law Dome, Byrd, EPICA Dronning Maud Land (EDML), Siple Dome, and Talos Dome. The data for each core is interpolated to 20 year time steps and standardised with respect to its own mean and standard deviation over the interval 9000 to 21000 years before 1950 AD (9-21 ka BP 1950). Estimated dating uncertainty in the composite (relative to GICC05) is ± 220 y during the interval 10-13 ka BP, ± 200 y during the interval 13- 15 ka BP, and ± 380 y during the interval i.e. 15-18 ka BP. Refer to Pedro et al., (2011) (Table 2) and original references for dating uncertainties in the individual cores. ABSTRACT SUPPLIED BY ORIGINATOR: Precise information on the relative timing of north-south climate variations is a key to resolving questions concerning the mechanisms that force and couple climate changes between the hemispheres. We present a new composite record made from five well-resolved Antarctic ice core records that robustly represents the timing of regional Antarctic climate change during the last deglaciation. Using fast variations in global methane gas concentrations as time markers, the Antarctic composite is directly compared to Greenland ice core records, allowing a detailed mapping of the inter- hemispheric sequence of climate changes. Consistent with prior studies the synchronized records show that warming (and cooling) trends in Antarctica closely match cold (and warm) periods in Greenland on millennial timescales. For the first time, we also identify a sub-millennial component to the interhemispheric coupling. Within the Antarctic Cold Reversal the strongest Antarctic cooling occurs during the pronounced northern warmth of the Bølling. Warming then resumes in Antarctica, potentially as early as the Intra-Allerød Cold Period, but with dating uncertainty that could place it as late as the onset of the Younger Dryas stadial. There is little-to-no time lag between climate transitions in Greenland and opposing changes in Antarctica. Our results lend support to fast acting inter-hemispheric coupling mechanisms, including recently proposed bipolar atmospheric teleconnections and/or rapid bipolar ocean teleconnections.
