Reece,^{2, 4} Julie Ditkof,² Carmen C. Atkins,² and Derek Sawyer³ Abstract We analyzed the particle size distribution of 46 samples from Integrated Ocean Drilling Program (IODP) Expedition 319 Hole C0009A in the Kumano Basin of the Nankai Trough. Using Shepard’s classification, we found that most samples fall into the clayey-silt classification. Clayey-silt is composed of 35%–88% silt-size particles, 11%–38% clay-size particles, and <20% sand-sized particles by weight. However, six samples contain more sand-sized particles and thus fall into either the sandy-silt or silty-sand category according to Shepard’s classification. Samples at Site C0009 were analyzed over a depth range of 1529–1591 meters below seafloor using the wet-sieve and hydrometer methods. ¹ Flemings, P.B., Reece, J.S., Ditkof, J., Atkins, C.C., and Sawyer, D., 2015.
