Uddannelses- og Forskningsministeriet - FNU - Isotope dynamics of nitrification as a key to nitrogen removal in coastal waters

Nitrification, the oxidation of ammonia to nitrite and nitrate, is one of the key processes in counteracting eutrophication of coastal waters, because it replenishes the substrates for the two ultimate removal pathways of reactive nitrogen, anammox and denitrification (Fig. 1). With this proposal we aim to elucidate the dynamics and regulation of nitrification in coastal waters and estuaries, especially those that are exposed to severe anthropogenic nutrient loading.
