    • 144Nd of a sample from the bulk Earth value of 0.512638 (46) in parts per 10,000. The high-atomic-masses Nd isotopes (142 to 150 atomic mass units) and their single oxidation state (+3) inhibit significant mass-dependent fractionation. Moreover, corrections applied during mass-spectrometry measurement eliminate effects of any natural mass-dependent fractionation.

    • The Sr isotopes and rare-earth-element patterns of leaches from this core match that of seawater, which is evidence for a marine rather than detrital origin for the Nd isotopes.

    • Nd at the core sites remain roughly constant. Thus, they would require evidence before they can be considered seriously. On the longer term, as explained in the text, there is good evidence that the Pacific end member remained nearly constant on glacial-interglacial time scales, whereas the North Atlantic end member is less well constrained, but current evidence indicates near constancy (15, 18).

    • A 35-cm interval in RC11-83, which has an average sedimentation rate through this section of 24 cm/1000 years [a 29-cm interval in RC11-83 (79, 20)], would correspond to a time period of 1450 years.

    • Most Nd and carbon isotope measurements in the deglacial and Bølling warming portion of the record were not made on the same sample depths or splits. We therefore conservatively confine our interpretations to lead-lag relationships >150 years or >3 cm of core length.
