Abstract:
Ice-rafted debris (IRD) data measured for discrete samples between ~117 and 158 revised metres composite depth (rMCD) at IODP Site U1307, Eirik Drift, offshore southern Greenland. Measurements consist of IRD weight percent (wt.%) in the ≥63 and ≥212 μm grain size fractions, and IRD grains per gram in the ≥125 and ≥150 μm grain size fractions. This data is provided against sample IDs, metres below seafloor (MBSF) depths, rMCD depths and age in thousands of years (ka). The time period covered by this dataset is ~2200 to 3200 ka, across the Plio-Pleistocene transition and the intensification of Northern Hemisphere glaciation.
