| In this work we studied some ecological factors and the floral composition of phytoplankton (micro plankton) during the 1953-1954 period. We measured successively: the temperature, the pH, the alkaline, the chlorine, the dissolved oxygen, the concentration of phosphates and nitrates. The water of the Ostend port passes the scale a-mesohaline to polyhaline. The sampling of the phytoplankton has been worked out one time or several times in a month. The Bacillariophyceae play an important role, the Dinophyceae are relatively rare, as the Chryosophyceae, and the Chlorophyceae are meeting during the whole year, with the exception of January, February and April, in little quantities, except for November. Dominant species are: <i>Coscinodiscus continues,... |
