4-4. Southwest of Hawaii (PC-13) 　　　　　　　　　　

Objectives
PC13 was recovered 135 km W of the southern tip of Hawaii island. Its location is just east of a large elongate N-S trending seamount, believed to be of Cretaceous age. This region has experienced a series of several landslide events.

Lithology
The lithology of PC13 is characterized by moderate yellowish brown clay interbedded with volcanic sand -silt layers in the upper section. The base of the section is comprised of a 3.2 m-thick black sand layer. It should be noted, however, that upon recovery of this core, a 200 cm gap was found from sec3 to sec5, and some in-flow may be present in the middle part of this core.
