Notes: CS = coarse-sand abundance. IRD = IRD abundance within the coarse-sand fraction. LSR = average sedimentation rate. DBD = sediment dry bulk density. CS IRD MAR = mass accumulation rate of the coarse-sand IRD. This is a sample of the table that appears in "ASCII Tables" in the Table of Contents.
