Tejo (Tagus) estuary (western Portugal)

Particulate inorganic carbon concentrations in the water column; Electrical conductivity of the water column; Chlorophyll pigment concentrations in water bodies; Dissolved oxygen parameters in the water column; Primary production in the water column; Total dissolved inorganic carbon (TCO2) concentration in the water column; Dissolved inorganic nitrogen concentration in the water column; Temperature of the water column; Concentration of suspended particulate material in the water column; Phaeopigment concentrations in the water column; Concentration of inorganic sulphur species in the water column; Alkalinity, acidity and pH of the water column

Fluorometers; discrete water samplers; salinity sensor; pH sensors; nutrient analysers; dissolved gas sensors

Data for primary production, using the oxygen method, are available for three stations of the Tejo estuary. The samples were collected every two weeks at three light penetration depths (100 per cent, 75 per cent and 10 per cent), at high tide.
