| 5 | 115 | 6 | The uppermost 30 cm of the core was intensively bioturbated through worm, mollusk and crustacea (crab) activities with overprinting of earlier traces. Larger structureless traces > 2 cm were probably caused by crustacea. Typical concentric structures left by mollusks were also observed. Worm burrows were rarely preserved below 30 cm. Sediment layering not discernable. | ||
| 115 | 190 | 6 | Seldom bioturbated from 115-190 cm with a few worm burrows and mollusk traces. Crab burrows and dwelling chamber at 173-182 cm depth. Sediment laminations were better preserved below 150 cm. Littorina littorina shell present at 171 cm. | ||
