Abstract

Long-term investigations of pore-water ammonium concentrations and sediment oxygen uptake were carried out in three different sediment types along a slope in Kiel Bight. The inverse relation between mineralization rates and ammonium concentrations at the three stations is explained by the differences in the role of various mechanisms transporting nutrients out of the sediments. Direct water exchange due to turbulent or density driven processes, bioturbation and pumping activity of benthic macrofauna and molecular diffusion are involved to various extents in nutrient fluxes out of the sediments studied. The role of different sediment types in the interaction with the pelagic system is discussed in a conceptual framework of pelagic system functioning in Kiel Bight.
