Abstract:
This dataset includes the results of the analysis of a marine sediment downcore record recovered from the Labrador Sea: core HU08-029-004 (61°27.49 N, 58°02.11 W, 2674 m). Analysis includes measurement of the radiogenic Nd isotope signatures in the authigenic Fe-Mn oxyhydroxide fraction of the bulk sediment (leachates) and of the totally dissolved residual silicate (detrital) as well as analysis of uncleaned foraminifera. The downcore records were sampled with resolution of about 1 kyr and cover roughly the last 33 ka.
