|---|---|---|---|---|---|---|---|
| Site | Depth (m) | Ca2+ | Mg2+ | Cl- | SO42- | NH4+ | |
| Shallow | 60 | 28.6 ± 6.1 | 145.4 ± 8.9 | 37.3 ± 0.9 | 20.2 ± 0.7 | <6 | |
| Intermediate | 153 | 25.3 ± 0.1 | 134.8 ± 7.0 | 38.4 ± 1.9 | 11.9 ± 0.4 | 20.3 ± 0.8 | |

Water samples were retrieved at the water–sediment interface in cores from the shallow, intermediate and deep site and measured by ion chromatography. Values are displayed in [μM] followed by one standard deviation.
