Several fining upward sequences with sharp bases and gradational tops. The top 36 cm of section 1 is soupy, probably fall-in, medium sands with abundant
planktic foraminifera. Mottling, with volcanic ash, and moderate to heavy Zoophycos bioturbation are evident throughout the core. Medium sands are darker
grey in color (5Y 4/1) with a high abundance of volcanic glass fragments, compared to the lighter colored silts and clays (5Y 5/2 and 5Y 5/1 respectively).

The core contains several fining upward sequences; lower contacts are sharp with gradational tops. They range from 25 cm to 1 m plus in thickness.
Foraminiferal sands are abundant along the scoured horizons in sections 4 and 5. Sections 6 and 7 are a slightly lighter grey color (5Y 6/1) than the upper
sections (5Y 4/1), which represent a higher calcium carbonate content; nannofossils (Emiliania huxleyi was identified in smear slides) are moderately
abundant. Bioturbation and mottling are moderately abundant throughout sections 2 to 7.

The core contains several fining upward sequences; lower contacts are sharp with gradational tops. They average 30 cm in thickness. The lower part of
section 6 and all of section 7 contains flow-in medium sands which distorts the thickness of sand layers. Parallel laminations within silt and clay horizons
