| 0 | 54 | 14 | 0-10 cm: intensively bioturbated with deformational structures from ?mollusks and ?echinoids.. A few hollow and sediment-filled burrows were discernable. 10-26 cm: frequent 3-5 mm diameter, hollow and unlined worm tubes. A few were lined or multiwalled, a head chamber from Pectinaria koreni was preserved. Some crab burrows were also present. Curved layering in larger burrows from mollusk activity. 26-40 cm: deformational structures from mollusk and ?echinoid activities with overprinting of older traces. Some plow soles were observed. Worm burrows themselves were not preserved, except towards the base. 40-54 cm: hollow, 3-5 cm diameter worm tubes were frequent. One U-shaped segment present. Sediment-filled burrows near base. Arcuate layering in larger burrows. | ||
| 54 | 81.5 | 14 | long, hollow and partially sediment-filled, worm burrows were more frequent down to 69 cm, deformational structures probably from mollusk activity dominate below. | ||
| 109 | 164 | 14 | 109-117 cm: frequent crab borro ws, radiating from central chambers. Fewer, longer worm burrows were also observed. Remnant sediment layering. 117-136 cm: sediment layering generally preserved, except where a large vertical burrow from a bivalve cuts through between 126-136 cm. Selective collection of coarse grains and grits along thin tubes at 126-128 cm. 136-151 cm: frequent burrows of small crustacea, generally sinuous, e.g. at 138-144 cm with dendritic pattern upwards.and downwards from a central chamber, at 150-151 cm with interconnected burrows. 151-164 cm: ohne visible biogenic activity with the exception of a large, irregular burrow between 151-155 cm. | ||
