Description

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
