Abstract:

 

The Gediz River is the largest fresh water source for İzmir  Bay.  Several studies have been carried out on the river's physical  and biogeochemical dynamics.  However, there has not been a particular  geographical focus on the mouth of the river.  In this study, along  the salinity gradient towards the bay in 2004 and 2005, the dissolved  inorganic nutrients were seasonally measured at the river mouth.  During the sampling period, the concentration of the constituents  showed variability in the range of 0.04-156 m M for NO3-, 0.02-12  m M for NO2-, 0-237 m M for NH4+, 0.02-26 m M for PO43-,  and 1-293 m M for SiO2, while the river discharge fluctuated  between 5.2 and 123 m3/s.  Resulting highly contrasted salinity  gradients between 0.29 and 39.62 psu significantly influenced the  concentrations of dissolved inorganic nutrients.  Furthermore,  simultaneous sampling carried out over the entire bay area provided an  opportunity to study the effects of the river on the bay during  periods of maximum and minimum discharge.
