Biogeochemistry of Tidal Flats

Biogeochemical transformations on water-column-suspended particles, at the sediment-water interface and in the sediments are studied Considering the hydrodynamic conditions, the influence of the different processes on the material budgets will be determined. A mathematical ecosystem model will be developed for the biogeochemical processes in the tidal flat sediments and at the sediment-water interface. On a higher level, a material budget will be established for a selected tidal flat area on the East Frisian North Sea coast (backbarrier tidal flat of Spiekeroog island).
