Data set name

Monitoring Phaeocystis blooms at a fixed station in Belgian coastal waters

Data holding centreUniversité Libre de Bruxelles, Ecology of Aquatic systems
CountryBelgium  Belgium
Time period1988 - 1992
Geographical area

1 station in the Belgian coastal waters (51° 26.00'N, 02° 48.50'E)


Ammonium and ammonia concentration parameters in water bodies; Chlorophyll pigment concentrations in water bodies; Other physical and chemical properties of suspended particulate material; Nitrate concentration parameters in the water column; Phosphate concentration parameters in the water column; Salinity of the water column; Silicate concentration parameters in the water column; Temperature of the water column; Phytoplankton generic abundance in water bodies


Acquisition of these data is carried out as part of European projects on eutrophication in the Southern Bight of the North Sea. This is part of a coordinated survey in the coastal zone of the Channel and the North Sea (U.K., France, Belgium, The Netherlands, Germany, Denmark), with the goal of assessing the seasonal and interannual variations of diatoms and Phaeocystis development. Data are normally available for the spring period (from March to June), with the exception of 1988 and 1992 (from February to September). Surface seawater is sampled weekly (1/month during summer) on R.V. BELGICA at a station representative of the Belgian coastal waters. Measurements of the different parameters are carried out either on board, or in the laboratory after storage in a Dewar bottle. Standard methods are used for the measurement of temperature, salinity (oceanographic probes), major nutrients (according to Grasshof), Chlorophyll-a (Lorenzen), phytoplankton countings (inverted microscope), bacteria and protozoa countings (for 1988, epifluorescence microscopy).
