Chlorophyll pigment concentrations in water bodies; Dissolved organic carbon uptake and production in the water column; Phosphate concentration parameters in the water column; Primary production in the water column; Secchi disk depth; Temperature of the water column; Concentration of suspended particulate material in the water column; Salinity of the water column; Nitrate concentration parameters in the water column; Ammonium and ammonia concentration parameters in water bodies; Nitrite concentration parameters in the water column; Carotenoid and flavenoid pigment concentrations in water bodies

The physico-chemical parameters like water column temperature and Secchi depth are measured during the sampling procedure. Water samples are transported to the laboratory and the measurement process of all other parameters starts in two hours after sampling. The procedure covers nitrate, nitrite, ammonium, phosphate, seston, salinity (conductivity); chlorophyll A, carotinuids and pheopigments concentration; glucose and amino-acid mixture uptake indices. The samples for primary production measurement are processed in the laboratory and then incubated in situ for a half day period from midday to sunset. Every sample is incubated in the corresponding depth.
