|---|---|---|---|---|---|
| 20 | 0.4000 | 0.800 | 0.000 | Mix of water and peat | |
| 19 | 1.0850 | 1.370 | 0.800 | Brown peat with a gradual gyttja-peat transition in the lower 10 cm. | |
| 18 | 1.4700 | 1.570 | 1.370 | Brown coarse detritus gyttja. UB = very gradual | |
| 17 | 1.5925 | 1.615 | 1.570 | Grayish-light brown silty-fine sand gyttja. UB = sharp | |
| 16 | 2.1075 | 2.600 | 1.615 | Brown-dark brown gyttja with higher algae and silt content between 240 and 210 cm. At 235 cm a 0.5 cm thin light brown silty layer occurs, possibly a tephra. | The uppermost 30 cm is richer in coarse detritus. UB = sharp |
| 15 | 2.9250 | 3.250 | 2.600 | Dark brown silty algae-rich gyttja with a 1 mm thin sand layer at 317.5 cm. | At 279.5 cm a light-grey 0.5 cm medium sand layer occurs followed by 4 cm of brownish-grey clayey, sandy silt gyttja ending with a thin grey layer at 275 cm. UB= very gradual. |
| 14 | 3.3500 | 3.450 | 3.250 | Silty-sandy gyttja clay, "diamictic", with gravel clasts and organic lenses. UB = sharp | |
| 13 | 3.4875 | 3.525 | 3.450 | Dark brown silty algae-rich gyttja with one light layer at 349 cm. UB = very sharp and possibly erosive. | |
| 12 | 3.5350 | 3.545 | 3.525 | Light grayish-brown silty gyttja, which starts and ends with distinctly light layers (tephras?). UB = very sharp | |
| 11 | 3.7125 | 3.880 | 3.545 | Dark brown silty algae-rich gyttja, thickly laminated with more coarse detritus above 378 cm. At 360 cm a 0.5 cm light layer occurs. UB = sharp | |
| 10 | 3.8975 | 3.910 | 3.885 | Greenish sandy silt, possibly a tephra. UB = very sharp | |
| 9 | 4.0625 | 4.215 | 3.910 | Brown silty, algae-rich fine detritus gyttja. UB = very sharp |
