Record of glaciations off the east greenland coast over the last 400KYR : SM-ND isotopic signature of marine clays

Abstract : We use Nd isotope signature of the clay-size fractions of sediments from the Southern Greenland rise to track deep current changes over the last climate cycle. Fine particle supplies to the Labrador Sea by Western Boundary UnderCurrent (WBUC) were strongly controlled by proximal ice-margin erosion and thus echoed the glacial stage intensity. In contrast, distal WBUC-controlled inputs from NE Atlantic have been less variable, except for a marked increase in surface-sediments that suggests unique modern conditions.
