Modeling the biogeochemical functioning of the Seine estuary and its coastal zone: export, retention, and transformations
Materials and methods
– Study area
– The ECO-MARS3D model
– Boundary conditions
– Validation measurements
Results
– General validation of the model
– Spatiotemporal dynamics of the estuarine and coastal water masses
– N, P and Si budgets: export and processing by the estuarine filter
– Phytoplancton biomass at sea
Discussion
– The filter effect of the estuary
– Phosphorus water-sediment exchange
– Difference between wet and dry years
– The biological response in marine waters
Conclusions
