The following parameters were measured: pH, dissolved oxygen (DO), temperature, concentrations of chlorophyll (a and b), concentrations of ammonium (NH4+), nitrite (NO), nitrate(NO3) and phosphate (PO43), particulate nitrogen (N ) content of the biomass, total suspended solids (TSS) and volatile suspended solids (VSS).
The pH measurements were carried out twice a day. Data on pH represent the highest value of the two measurements
of the day day (à supprimer).
