A sediment core from the north-east North Atlantic contains high-resolution co-registered foraminiferal δ 18 O and ice-rafted detritus (IRD) records for the last deglaciation. These reveal a distinct ice-rafting event that occurred at the time of Greenland Interstade 1d (GI-1d), a feature also seen...
