Case study area
This estuary is one of the largest in Europe, with a broad shallow bay covering an area of about 320 km
. It is mesotidal with semi-diurnal tides. The Tagus river is the main source of freshwater to the estuary.
monitoring program with monthly sampling at four sites has been running since 1999. This measures chlorophyll a and other photosynthetic pigments by HPLC, total suspended matter, in water radiation, Secchi disk, nutrients content, and in some years, phytoplankton cell counts. The estuary demonstrates a maximum chlorophyll concentration in the spring/summer and minimum in the winter.
