چکیده انگلیسی
In this paper, the main physical processes involved in the onset of phytoplankton spring blooms are examined in a tide-dominated estuarine embayment, characterized by weak current velocities, using a 1-D ecosystem model (the European Regional Seas Ecosystem Model) coupled with a 3-D physical model (the Princeton Ocean Model coupled with a sediment transport model) via the off-line method. Simulation results show that a reduction in vertical mixing, caused by the episodic input of buoyant, freshwater inflows from a reservoir during the period of neap tides, is the main physical controlling process on the occurrence of spring algal blooms. Furthermore, sensitivity tests using: (1) layered and (2) depth-averaged monthly vertical eddy diffusivity values reveal that the timing of phytoplankton spring blooms in the model is strongly affected by the parameterization of vertical diffusivity.
