    Abstract

    The well known diel periodicity of phytoplankton photosynthesis under constant light can be explained, to a large extent, by diel periodicity of the photosynthetic activity per unit of chlorophyll; thus, to the same extent, this rhythm is independent of chlorophyll concentration or biomass, and it reflects an endogenous cycle. On the other hand, the periodicity which results from long term (24 hours) exposures under "simulated in situ" conditions belongs to a quite different type. Both phenomena are discussed here on the basis of parallel experiments made during cruise 8 of R/V "Anton Bruun" in the Mozambique Channel (International Indian ocean Expedition).
