This thesis investigated nitrogen processes in a flooded peatland and coastal sediments
of the southern Baltic Sea. In the 1st part the nitrogen fixing rates in resuspended
sediments was measured which could contribute to the pelagic nitrogen pool. In the
2nd part it was determined if rising salinity in flooded peatlands affect ammonium
assimilation and nitrification which could cause eutrophication there. In the 3rd
part the seawater-induced ammonium release from soil was investigated (cation exchange)
which could increase nitrogen concentrations in coastal areas.

Diese Dissertation untersucht Stickstoffprozesse in einem überfluteten Torfgebiet
und Küstensedimenten der südlichen Ostsee. Der erste Teil der Dissertation behandelte
die Stickstofffixierungsraten in supendierten Sedimenten. Der zweite Teil der Thesis
untersuchte ob Meerwasser die Stickstoffumsetzung im überliegenden Torfwasser hemmt
was zu Eutrophie führen könnte. Im dritten Teil der Thesis wurde getestet, ob Kationenaustausch
zwischen Meersalz und Ammonium zu erhöhtem Ammoniumverlust aus dem überfluteten Torfgebietes
führt, welches Grundwasser und anliegende Küstengewässer gefährden könnte.
