Description
Summary:This dataset contains measurements of terrigenous particle-size distributions on Pliocene sediment from Integrated Ocean Drilling Program Site U1359 on the Wilkes Land margin. Biogenic silica, carbonate, and organic matter were removed through addition of 10mL aliquots of 30% H2O2, 2mL aliquots of 10% HCl to ~50-100mL suspension on a hot plate, and after supernatant was removed, digestion in 0.2 N NaOH at ~85 degrees for 1 hour. Dispersion was through heating with sodium pyrophosphate. Samples were measured on a Malvern Mastersizer 2000 with a Hydro 2000MU (A) accessory, using a Refractive index of 1.6 (Illite) and an absorption coefficient of 0.9. Results are in (vol. %) per size class, with diameter range equivalent to the diameter of spheres with the same volume as measured particles.
