Última Seasonal variation of phytoplankton populations and primary production in the Sluice dock at Ostend (Belgium) OMA Mommaerts-Billiet, F.; Mommaerts, J.-P.; Daro, M.H.. The Sluice Dock at Ostend has been investigated for phytoplankton populations and primary production for the years 1971 and 1972. Nannoplankton is demonstrated to take a prominent part in pelagic primary production. The seasonal cycle shows a short spring outburst of <i>Eutreptiella marina</i> da Cunha followed by a depressed production period (May). Summer is the most productive; several nannoplankton populations appear successively in this period. The depression in May is discussed in relation to zooplankton activity.

West in the presence of crude oil and emulsifiers OMA Mommaerts-Billiet, F.. Phytoplankton response to environmental pollution by oil and emulsifiers has been studied. The nanoplanktonic flagellate <i>Platymonas tetrathele</i> has been assayed with increasing concentrations of crude oil, industrial non-ionic emulsifiers and mixtures of these products. Cultures poisoned with an emulsifier with an aromatic solvent exhibited a very long lag phase. Diminished growth rates were observed for all the products tested most of the time at concentrations above 50 ppm. The mixtures showed a toxicity close to that of the emulsifier component at its concentration in the mixture and lower than that of the crude oil alone. Fine structure modifications have been investigated and the possible ecological effects of such pollution have...
