Essai de bilan annuel du transfert de l'azote dans le bassin de chasse d'ostende As nutrients are withdrawn from the environment in the proportions required for the growth of primary producers, the C/N ratio known from the literature provides a stoechiometric basis for evaluating the uptake of nitrogen resulting from phytoplankton and phytobenthos activity.

Abstract

As nutrients are withdrawn from the environment in the proportions required for the growth of primary producers, the C/N ratio known from the literature provides a stoechiometric basis for evaluating the uptake of nitrogen resulting from phytoplankton and phytobenthos activity. This activity has been measured respectively by14CO2 incorporation and O2 production in in situ and in vitro experiments. The production of the phytoplankton community for the period considered (6 months) amounts to 112 g C/m2. That of phytobenthos might well be one third of this amount (37 g C/m2). Therefore, nitrogen uptake would have been 14 g and 4 g N/m2. As the yearly inorganic nitrogen input from the harbour of Ostend is 1.5 g, the turnover is about 10.
