The duration and sequence of events recorded in Heinrich layers at sites near the Hudson Strait source area fbr ice-rafted material are still poorly constrained, notably because of the limit and uncertainties of the C-14 chronology. Here we use high-resolution Th-230-excess measurements, in a 6 m se...
