BOTTOM SAMPLING

Table 7 shows the description of bottom samples.


Table 7: Bottom samples description. B=Box-corer,C=gravity core.
STATION SAMPLE WHERE DESCRIPTION
01 B-01 S-Bojana Clay sediment. Very hydrated in the first 2 cm. Compact, lower water content from 2 to 25 cm. Plastic. No (or very low) Bioturbation. No smell. Colors:Top (0-2 cm) yellow/Brown; 2-25 cm Olive green (very uniform); No clast and no shell fragment.
02 B-02 S-Bojana Clay sediment. Very hydrated in the first 2 cm. Compact, lower water content from 2 to 29 cm. Plastic in the bottom (22-29). Some signal of Bioturbation (warms). No smell. Colors: Top (0-2 cm) yellow/Brown; 2-22 cm Olive green; 22-29 cm Gray/Olive green; No clast and no shell fragment
03 C-02 S-Bojana Cut information Sp I Bottom (cm 220) silty-clay with shell fragment. Compact, low water content. Color: Gray Olive. Sp II 120 cm Fine Clay sediment; Color Olive/olive gray; Sp III 20 cm Olive green, clay sediment, hydrated.
04 B-03 S-Bojana Clay sediment. Very hydrated in the first 2 cm. Compact, lower water content from 2 to 30 cm. Plastic in the deepest part (25-30). Some signal of Bioturbation by polychaetes. Colors: Top (0-2 cm) yellow/Brown; 2-30 cm Gray/Olive green; Rare clast and shell fragment.
05 C-03 S-Bojana Sp I Bottom (cm 220) sandy clay with shell fragment. Compact, high water content. Color: Gray Olive Sp II 120 cm Fine Clay sediment. Seems to be very oxidized Color Black gray, Sp III 20 cm Olive green, clay sediment, hydrated.
06 B-04 SE-Bar Clay sediment. Very hydrated in the first 3 cm. Low water content 3-18 cm. Compact, lower water content from 18 to 28 cm. Plastic clay on the bottom. Bioturbation, polychaetes. No oxidation. Colors: Top (0-2 cm) yellow/Brown; 2-18 cm Olive green/gray; 18-28cm gray/green.
07 C-04 SE-Bar Sp I Bottom (cm 120) sandy-clay very dark (Tephra level?) with probably shell fragment. Color: Gray/black Sp III 20 cm Olive green, clay sediment, hydrated. Yellow brown.
08 B-05 SE-Bar Fine clay sediment. Very hydrated in the first 2 cm. Compact and with low water content from 2 to 20 cm. Compacted (over-consolidated?) in the deepest part (20-31). Worms-Bioturbation. No clast, but rare shell fragment on the bottom. Colors: Top (0-3 cm) Brown/yellow, 2-20 cm Olive green, 20-31 olive green/gray
09 B-06 SE-Bar Clay sediment. Very hydrated in the first 3 cm. Lower water content 3-25 cm. Quite uniform. At c.10-12 cm seems to be a fracture zone with an high water content (Heart-quake??). Possible Bioturbation but not so much evident. No oxidation.
10 C-06 SE-Bar  
11 B-07 SW-Bar Very coarse sandy/gravel sediment with many reworked biology: Shell fragment and live, corals Bryozoa, sponge living crustacea. Colors:Top (0-17 cm) Dark and gray sandy clasts,
12 B-08 SW-Bar Clay sediment. Very hydrated in the first 3 cm. Lower water content 3-18 cm. Very homogeneous. 18-29 cm Silty clay with progressive increase od coarse fraction. Bioturbation Shell and worms.. Colors: Top (0-3 cm) yellow/Brown, 3-18 cm Olive green/gray, 18-29 Gray/green
