Reply to comment by S. Peacock on “Glacial-interglacial circulation changes inferred from 231Pa/230Th sedimentary record in the North Atlantic region”

Gherardi, J. -M.; Luo, Y.; Francois, R.; McManus, Jerry F.; Allen, S. E.; Labeyrie, L.

Peacock [2010, P10 hereafter] takes issue with several aspects of our recent article [Gherardi et al., 2009, G09hereafter]: (1) our description of the modern Atlantic meridional overturning circulation (AMOC), (2) apparent inconsistencies between modern circulation and our Holo-cene sedimentary 231Pa/230Th bathymetric profile, and (3) our use of cores for reconstructing AMOC from locations that do not lie beneath the Deep Western Boundary Current (DWBC). We welcome the comment as it affords us the opportunity to clarify important aspects of our approach to studying paleocirculation and to address any potential mis-understandings arising from the wording of our original text.
