| 0 | 110 | 9.5 | Small mussels in living position down to 7 cm with siphons to core surface, deep burrow of Pectinaria koreni from 14-42 cm with layering parallel to walls (?grazing), bent at top, and a few hollow and filled worm tubes, especially between 55-90 cm. | ||
| 110 | 192.5 | 9.5 | A few thin worm tubes, vertical and inclined, hollow and sediment-filled (coarser) were observed down to 160 cm. Concentric traces due to mussel movement and resting position with faint vertical traces. Strongly bioturbated below 182 cm, mainly through mollusks | ||
| 192.5 | 282 | 9.5 | Faint vertical burrows to 218 cm, frequent hollow burrows with bifurcations and dendritic pattern down to 240 cm, less frequent, partially sediment filled, of various sizes, and without birfurcations down to 282 cm. Dwelling chambers were also present. | ||
