Changes in North Atlantic Deep Water strength and bottom water masses during Marine Isotope Stage 3 (45-35kaBP)

Abstract:

The strength of the North Atlantic Meridional Overturning Circulation during climatically highly variable Marine Isotope Stage (MIS) 3 has attracted much attention in recent years. Here we present high-resolution Nd isotope compositions of past seawater derived from authigenic Fe-Mn oxyhydroxides recovered from drift sediments on the Blake Ridge in the deep western North Atlantic (ODP Leg 172, Site 1060, 3481m water depth). The data cover the period from 45 to 35kaBP, tracing circulation chan...
