Parameters of Lagoon

The Hydrobiological Station of Chioggia collects data on the following environmental parameters.
Water temperature: expressed in degree Celsius, measured with a mercury-in-glass thermometer (to the nearest 0.1°C)
Salinity: expressed in g/kg, estimated from the measurement of temperature and density (densimeters Seewasser – Araometer Richter &Wiese K.G.)
pH: scale 0-14, measured with pH-meter CRISON mod. BASIC20 (from 1992)
Dissolved O2: expressed as ml/l, measured with Winckler’s method.
Air temperature: expressed in degree Celsius, measured a mercury-in-glass thermometer (to the nearest 0.1°C)
All data are recorded in a water sample taken at 0.5 m of depth in front at the Hydrobiological Station (Venetian Lagoon, close to the southern channel connecting the lagoon to the open sea). Air temperature is recorded at the Hydrobiological Station.

All data are recorded on a daily base, excluding week end.

Data are available from 1973 (data missing from November 1990 to September 1992).
The English version of the database will be available soon.
