We conducted two sampling campaigns following the same protocol, one in winter, one in summer 2019.
- Surface water samples, pore water samples along a depth profile in the pore water from 2 - 20 cm sediment depth, every 2 cm
> Sampling interval: 1 hour, for 7 (winter) and 11 (summer) hours
> Parameters: 18 trace organics, sulfate, nitrate-N, dissolved Fe and Mn, oxygen
- Continuous measurements
> CTD-divers in surface water and different depths of the sediment: 4, 8, 12, 16, 20 cm, measuring pressure P, temperature T and electrical conductivity EC
> a temperature lance, vertical in sediment, in summer, sensor depths: 0, 5, 20, 22, 25, 30, 60 cm
> Pressure difference between surface water and in different sediment depths, measured with 2 devices: 0, 5, 7, 10, 15 cm and 0, 5, 10, 12, 15, 20 cm
- Sediment data: sediment cores taken at sampling sites after each sampling campaign, split up in at least two depths which were analysed for:
> saturated hydraulic conductivity (Ksat, normed to 10°C)
> porosity, grain size distribution
> total carbon content TC
