Sediment Sampling details
Device used: Core - unspecified
| Contents | Top (m) | Base (m) |
|---|---|---|
| 0-5.5cm: relatively sloppy, slightly silty mud. H2.5Y4/4 Olive Brown. Massive | 0 | 0.055 |
| 0-5.5cm | 0 | 0.055 |
| 0-6cm for SS | 0 | 0.06 |
| 5.5-32.3: probably the same sediment type (interrupted by ash layer at 19.0-19.2cm). Mottled silty clay, mainly H2.5Y4/4 Olive Brown, with darker-grey patches. Worm burrows are common. Sharp transition to next. | 0.055 | 0.323 |
| 10-13cm | 0.1 | 0.13 |
| 20-23cm | 0.2 | 0.23 |
| 28-31cm | 0.28 | 0.31 |
| 32.3-52cm: H2.5Y3/2 Very Dark Greyish Brown, mottled silty clay. Basically similar to overlying unit but with highre proportion of dark mottles, which are almost dominant. Worm burrows present. Sharp, deformed (concave downwards) boundary to next, perhaps due to coring. | 0.323 | 0.52 |
| 36-39cm | 0.36 | 0.39 |
| 45-48cm | 0.45 | 0.48 |
| 52-64.2cm: H2.5Y5/4 Light Olive Brown (but still oxidised) silty clay, similar to host of unit 2, with only scarce dark mottles or discontinuous layers. Sharp transition to next. | 0.52 | 0.642 |
| 55-58cm | 0.55 | 0.58 |
| 64.2-70cm: H2.5Y3/2 Very Dark Greyish Brown ? same as Unit 3. True bedding boundary to next. Sharp? | 0.642 | 0.7 |
| 65-68cm | 0.65 | 0.68 |
| 70-75cm | 0.7 | 0.75 |
| 70-76cm: H2.5Y4/4 Olive Brown, silty clay. Similar to Unit 2a but fewer mottles. | 0.7 | 0.76 |

| Black sand which probably lay on top of core, but has washed up the line. Would have only been a few mm thick at most | ||
| Pebble within previous mud sample | ||

| Sequence may represent continuous sedimentation with subtle variations by whatever causes the dark mottles. Core catched (ring) | ||
