Abstract

Within the Harz mountains, Central Germany, two sub-catchments from the intensively studied Selke basin were selected for the investigation of nitrogen dynamics in agricultural dominated headwater catchments. The dataset comprises detailed data of water samples collected in two sub-catchments of the Selke basin: the Meisdorfer Sauerbach and Schäferbach catchment. The two streams are tributaries to the Bode catchment, thoroughly studied within the TERENO network. With stable isotopic signatures of nitrate in various hydrological compartments (e.g. soil water, groundwater, surface water and precipitation) as well as data of nitrate concentrations, discharge and precipitation measurements, an analysis to further understand processes within the groundwater-surface water continuum of the two catchments is intended. Analysis as part of a master’s thesis revealed that even though, results of δ15N-NO3 and δ18O-NO3 are highly variable, both catchments are clearly influenced by agricultural land use. Thus, manure and fertilizers are identified to be two of the main anthropogenic nitrogen sources. Furthermore, the Meisdorfer Sauerbach shows an urban influence of the city Opperode located close to the stream. Additionally, septic waste is determined to be one of the main anthropogenic sources within this catchment. Biogeochemical processes, such as nitrification, denitrification, assimilation, and the decoupled enrichment of δ15N and δ18O, influence the stable isotopic signature of both catchments.
