Phase relationships of North Atlantic ice-rafted debris 
and surface-deep climate proxies during the last glacial period.

  <Summary>
    <Abstract>We report stable isotope, core scanning XRF, and ice-rafted detritus 
(IRD) data in glacial-aged sediments from piston Core KN166-14-JPC-13 
(hereafter referred to as JPC-13) retrieved at 53.1°N 33.5°W on the 
southern Gardar Drift, North Atlantic. A chronology was established 
by correlating millennial-scale features in the benthic d18O record 
to Portuguese Margin Core MD95-2042. Once the alignment of benthic 
d18O of JPC-13 to MD95-2042 is fixed, the relative timing of proxy 
variables is used to determine the phasing of changes in IRD and 
surface-deep hydrography. Each peak in North Atlantic IRD coincided 
with a decrease in benthic d18O that, in turn, has been linked to 
warming in Antarctica (Events A1-A7). The IRD pulses are followed 
shortly thereafter by abrupt decreases in planktonic d18O, indicating 
warming and increased heat transport to the subpolar North Atlantic 
associated with Greenland interstadials (GIS) 8, 12, 14, and 16-17. 
Grain-size and elemental (K/Ti) variations indicate that Iceland-
Scotland Overflow Water (ISOW) was stronger during these long, 
warm interstadial periods of Marine Isotope Stage (MIS) 3. 
The results are consistent with interhemispheric phase relationships 
inferred from Iberian Margin sediment cores and with methane 
synchronization of Greenland and Antarctic ice cores. 
 
          STUDY NOTES: Stable isotope, core scanning XRF, and ice-rafted detritus (IRD) 
data from piston Core KN166-14-JPC-13 collected from the southern 
Gardar Drift, North Atlantic Ocean.
