Characteristics of freshly collected sediments
| Location | Water depth (m) | Bottom water temp (°C) | O2 penetration deptha (cm) | NO3− penetration depthb (cm) | Max NO3− concnc (μM) |
|---|---|---|---|---|---|
| Aarhus Bay station 6 | 16 | 6.5 | 0.3 ± 0.1 | 1.2 | 19 |
| Skagerrak S6 | 380 | 6 | 0.6 ± 0.3 | 1.5-3 | 15 |
| Skagerrak S9 | 695 | 5.5 | 1.7 ± 0.6 | 2-4 | 35 |
a
Mean ± standard deviation; n = 3 or 4.
b
Range of two or three profiles.
c
Highest NO3− concentrations observed in pore water profiles. The maxima were typically located near the depth of oxygen depletion.
