Diagenesis in subrecent marine sediments in the Eastern Scheldt, Southwest Netherlands

The diagenesis in fine-grained sediments from a 300 to 400-years-old Dunkirk deposit, exposed on the intertidal flat, was studied at a site in the Eastern Scheldt. A new in situ pore water sampling technique that allowed repeated sampling at exactly the same place was used to monitor the seasonal fluctuations in interstitial water composition. The pore-water sampler proved to be useful for monitoring seasonal variations in the pore-water composition, because spatial variability as a disturbing factor could be ruled out. The use of this sampler is advised for unconsolidated sediments in salt ma... Mehr ...
