We present the results of grain-size analysis performed on hemipelagic sediment from Sites 1173, 1174, 1175, and 1177 at the Nankai Trough. Analyses of the <63-µm fraction were performed with a laser particle counter, and results were converted to equivalent settling diameters by means of an empirical regression with data from pipette analysis. The relations among grain size, porosity, bulk density, void ratio, and moisture content are influenced by the increasing compaction of sediment with depth as well as facies changes. Thus, departures of bulk density and porosity from normal compaction trends cannot be attributed to grain size on the basis of our laboratory results.

Sediment depth is given in mbsf. Porosity, bulk density, void ratio and water content from Shipboard Scientific Party (2001, doi:10.2973/odp.proc.ir.190.101.2001, in Moore et al. (2001)).
