| Contents | Top (m) | Base (m) |
|---|---|---|
| Brown mud with gritty foraminiferal tests and periodic bioturbation as evidenced by dark circular worm burrows. No laminations observed except for a 0.5cm thick dark coloured bed @ 31cm. Transitional colour change to next | 0 | 0.55 |
| Sample @ 20cm | 0.2 | |
| Sample @ 40cm | 0.4 | |
| Fining upwards sequence. Black volcanic sand layer @ 68cm is about 1cm thick. Sand grains ~1mm in diameter at base fine quickly upwards to volcanic silt @ 67cm. No obvious black volcanic component above 62cm. At bottom sharp transition to next | 0.56 | 0.68 |
| Gray-brown to brown clay with foram tests. Heavily bioturbated and mottled with no obvious laminations | 0.68 | 1 |
| Sample @ 80cm | 0.8 | |
| Sample @ 98cm | 0.98 | |
| Distinct colour change from brown @ 98cm to olive @ 102cm (H5Y513 Olive). A zone of discontinuous black clay is evident @ ~100cm. No other laminar features are obvious. Probably bioturbated throughout. Layer is ?harder to deform? than rest of core and has lower water content. Transitional to next. | 1 | 1.3 |
| Sample @ 101cm | 1.01 | |
| Sample @ 120cm | 1.2 | |
| Light Olive Gray (5HY6/2) silty clay. No obvious features except for mottled texture (bioturbated?) and higher shear strength than brown clay. Sharp to next | 1.3 | 1.35 |
| Grey silty sand @ 132cm | 1.32 | |
| Wet brown clay | 1.35 | |
| Sample @ 140cm | 1.4 | |
