| contents | Quantification of ice-rafted debris (IRD) abundances in deep-sea records using three independent methodologies of obtaining IRD abundances and how different approaches will affect determinations of mass accumulation rates (MARs). The three methodologies for this cross comparison of methods include: counting clasts >2 mm in x-radiograph images; the sieved weight percentage of the medium-to-coarse sand fraction (250 μm-2 mm); and volumetric estimates of the >125 μm sand fraction using Laser diffraction Particle Size Analysis (LPSA) methods to determine particle size. The data are collected from the Wilkes Land and Ross Sea region of Antarctica, using cores RS15-LC42,RS15-LC48, IODP sites 1361 and ODP site 1165. |
