Sharp contact at the top of Unit III, with laminated very fine sand above and foraminifer-bearing clay below at 91 cm (interval 308-U1320A-17X-2, 68–102 cm). B. Laminated mud with burrows and discontinuous silt laminae at 108.5 cm (interval 308-U1320A-17X-2, 98–132 cm). C. Bioturbated clay, showing a large dark burrow at 124–134 cm (interval 308-U1320A-17X-6, 108–142 cm). D. Bioturbated clay showing a large dark burrow at 130–134 cm and scattered fine sand grains (interval 308-U1320A-17X-6, 131–150 cm). E.
