Measuring stations in Niedersachsen
not near the mainland
Philippart & Cadée, 2000
Western Dutch Wadden Sea: Salinity (Zimmermann, 1976)
IJsselmeer influence in Western Dutch Wadden Sea prominent
In Niedersachsen, there is no permanent freshwater source!
Slope of DIP-curves
Nutrient budget: summer values near the islands
Nutrient budget: inter-basin exchange is small values near the islands
Stanev et al., 2003
Sluices: Variability of runoff values near the islands
Sluices: nutrient concentrations values near the islands
Exchange with North Sea: Time constant values near the islands
Exchange constant 3 days
Rain (EMEP): values near the islands
only in winter
3 days exchange
Export of dissolved nutrients values near the islands
Conceptual model for nutrient dynamics:
depth function values near the islands
Essential assumption: mortality of phytoplankton is depth dependent (filter feeders)
Ebenhöh et al., 2004
What is the essential difference between Niedersachsen and the other two regions??
Can we treat the entire Wadden Sea in the same way?
