Computation of nutrient pools and fluxes at the entrance to the Baltic Sea , 1974 – 1999
Monthly time series of nutrient pools and transport in the Baltic Entrance were computed for the period 1974–1999 from a combination of hydrodynamic model results and observational data obtained in national monitoring programmes. Significant seasonal variations in both nutrient pools and transport were found. For example, inflowing dense nutrient-rich Skagerrak water causes net transport of dis...
متن کاملReduction of Baltic Sea Nutrient Inputs and Allocation of Abatement Costs Within the Baltic Sea Catchment
The Baltic Sea Action Plan (BSAP) requires tools to simulate effects and costs of various nutrient abatement strategies. Hierarchically connected databases and models of the entire catchment have been created to allow decision makers to view scenarios via the decision support system NEST. Increased intensity in agriculture in transient countries would result in increased nutrient loads to the B...
متن کاملModelling climate change effects on nutrient discharges from the Baltic Sea catchment: processes and results
The effects of climate changes on nutrient discharges within the Baltic Sea catchment were modelled, indicating increases in concentrations of phosphorus, but decreases in nitrogen for the southern Baltic Sea catchment. The process-based hydrological and nutrient flux model, HYPE, was set up for the entire Baltic Sea catchment area. The model was then used to examine how water and nutrient flux...
متن کاملAssessment of sediment quality in Baltic Sea coastal waters
The investigations on the quality status of the sediments in the German Baltic Sea coastal waters focused on the natural background as assessment basis. On this basis, the chemical sediment quality can be evaluated. Furthermore, the decision about the relocation of dredged material from federal waterways depends on this assessment. The sediment quality of the German Baltic Sea coastal waters be...
متن کاملModelling of sediment nutrient fluxes for a pulsed organic load
A sediment model has been developed to simulate the Sediment Oxygen Demand (SOD) and sediment nutrient fluxes after a sudden input of Particulate Organic Matter (POM). Compared with previous sediment models, the main model advancements are the use of a continuous function to represent the kinetics of POM diagenesis and inclusion of the biomass content in POM diagenesis. Laboratory experiments a...
