WATER QUALITY RESULTS

Trophic Level in Estuary

 

For three zones defined according to salinity distributions, was calculated the cumulative frequencies for Clorophyll a , in order to classified the trofic activity in estuary:

Seawater zone

Mixing zone

Tidal Freswater zone

Marateca zone

 

 

Annual Budgets per Zone in Estuary

 

The boxes method, allow as to calculate the exchanges between boxes  for several properties. Next, is represented annual budgets per zone in estuary for phytoplankton, ammonia and nitrate:

Phytoplankton

Ammonia

Nitrate
